- Description: This mini-thesis investigates the concepts of refusal and rupture as a postdramatic revolt and how these terms can be applied and read within the context of analysing contemporary devised performance in South Africa. The argument focuses on the efficacy of Hans-Thies Lehmann’s postdramatic terminology and the potential of its use in an appreciation of contemporary performance analysis. I investigate the potential in South African contemporary devised performance practice to challenge prevailing modes of traditional dramatic expectation in order to restore the experience of discovery and questioning in the spectator. This research is approached through a qualitative process which entails a reading and application of selected critical texts to the analysis with an application of Lehmann’s terminology. This reading/application is engaged in a dialogue with the interpretative and experiential aspects of selected South African devised performances with particular focus on four cross-disciplinary works selected for analysis. Chapter One functions as an introduction to the concept of postdramatic theatre and the application of the terms refusal and rupture as deconstructive keywords in the process of a devised performance. Chapter Two is an analysis of several South African contemporary performances with particular focus on Body of Evidence (2009) by Siwela Sonke Dance Company, Wreckage (2011) a collaboration by Ubom! Eastern Cape Drama Company and First Physical Theatre Company, Discharge (2012) by First Physical Theatre Company, and Drifting (2013) by The Rhodes University Drama Department. This mini-thesis concludes with the idea that with an understanding of refusal and rupture in a postdramatic revolt, contemporary devised performance achieves an awakening in its spectators by deconstructing the expectation of understanding and the need for resolve; the assumption and need for traditional dramatic structures and rules are challenged. Instead, it awakes an experience of discovery and questioning.

- Description: This study sets out to investigate democratic participation in South Africa and the role that media play and can potentially play within this context. It considers a social movement, as one way in which citizens can organise themselves and make their voices heard to improve their chances of making a meaningful contribution to democracy. It employs Susan Bickford's theory of 'political listening', which offers a potential solution to the lack of political representativeness and inclusiveness, by focusing on the way citizens relate to each other through speaking, listening and dialogue. This study examines whether the interaction between learners and the social movement Equal Education could be considered 'political listening', and the current and possible role of the media within this context of participation. The study also attempts to develop and make a contribution to the language of description for the theory of political listening in order to map it onto the data. Using evidence or data gathered through observation of Equal Education's youth group meetings with learners and in-depth interviews with learners, youth group facilitators, Equal Education staff members and journalists, this study shows how the interaction amongst learners and between Equal Education and learners could be considered political listening and how the social movement works as a democratic project which offers learners an opportunity to exercise their citizenship. Furthermore, it also details the current role of the media and possible role of the media as perceived by Equal Education, learners and by journalists who report on Equal Education's activities. The study does not make conclusive claims about whether 'political listening' occurs between Equal Education and learners and the media because the study is exploratory in nature and involves a lot of trial and error when it comes to applying the theory of political listening to interview and textual data, which is a communication context that the theory is only beginning to chart.

- Description: The Namibian education system has undergone a policy shift from a top-down leadership practice or head-centred leadership to a more shared form of leadership in schools. Existing policy documents call for teacher participation in school level decision-making structures and processes as teachers often are involved in other activities and have been through life experiences which equip them with leadership skills. These policies clearly stipulate that school principals cannot lead and manage the schools alone, but should involve teachers and other stakeholders in leadership activities. This study explored teacher leadership in a rural primary school in the Otjozondjupa region of Namibia. The study explored the understanding of the concept teacher leadership, the practice of teacher leadership and the enhancing factors as well as barriers to teacher leadership practice. A qualitative interpretative case study was conducted. Interviews, document analysis, focus group interviews, a questionnaire and observation were employed to produce data with regard to teacher leadership practices in the case study school. The data were analysed thematically using Grant’s (2008) model of teacher leadership. Findings revealed that the concept of teacher leadership was understood as teachers leading both within and beyond the classroom. Teacher leadership was practiced across the fours zones of teacher leadership (after Grant, 2008), but to varying degrees. It could be categorized as emergent teacher leadership (after Muijs and Harris, 2005) within a formal distributed leadership framework (MacBeath, 2005). Teacher leadership in the case study school was enhanced by collaboration among staff and involvement of teachers in school level decision-making. However, barriers to teacher leadership at the case study school included holding on to power by the principal, teachers’ negative attitudes towards teacher leadership, a lack of incentives, a lack of time due to a heavy work load and a lack of professional development.

- Description: This research investigated the impact of language policy implementation towards the enhancement of community participation in the Nelson Mandela Metropolitan Municipality (NMMM).The NMMM is an organisation tasked with ensuring equal distribution of services to local communities. This municipality was chosen on the basis of its commitment to communicate effectively with the community and in turn encourage the community to participate fully in municipal activities. The study is conducted within the parameters of the Constitution of South Africa (1996) which states that in order to ensure language equity, all official languages must be used for the promotion of multilingualism and advancement of communities. The study therefore investigated the language policy of the NMMM and its implementation with regard to the use of all three official languages of the region, namely English, isiXhosa and Afrikaans for organisational communication. Gaps in the implementation of the municipal language policy were identified by acquiring information from selected officials responsible for service delivery and selected members of the communities who receive the services. A literature survey was conducted to investigate and conceptualise the nature of language policy development and to determine the responsibilities for policy implementation. A descriptive approach was used in the study, with the data collection coming from primary sources, such as NMMM officials and members of the community; and secondary sources, such as municipal records. A number of recommendations regarding the improvement of language policy implementation by the municipality’s Language Unit were made. It is envisaged that these changes could impact positively in encouraging community participation and ultimately improve service delivery.

- Description: Communal rangelands sustain a large proportion of the livestock in South Africa. A few dominant grass species contribute to the bulk of the livestock forage in these rangelands. Little is known on the chemical composition and in vitro ruminal fermentation characteristics of grass species grazed by ruminants in the communal grazing lands of Eastern Cape Province in South Africa. The objectives of this study were therefore to investigate seasonal and altitudinal variations in biomass yield, chemical composition, and in vitro ruminal degradability and cumulative gas production of selected (dominant) grass species. The grass species were collected over four seasons (summer, autumn, winter and spring) from three altitudes/landscape gradients (upland, gentle sloppy and bottomlands) across two communal areas (Hala in highland (Highveld) and Gqumashe in lowland (Lowveld)) of the Eastern Cape province, South Africa. In each altitude, three 50 m x 20 m plots, which served as replicates were marked to collect vegetation samples. A 5 x 4 x 3 factorial experiment in a randomised complete block design was used with season, altitude and grass species being the main factors, and with the plots within altitudes serving as blocks (replicates). Data analysis was done separately for the two communal study areas using the General Linear Models (GLM) procedure of SAS to test differences between species, seasons and altitudes. The common grass species in both grazing lands were Cynodon dactylon, Eragrostis chloromelus, Eragrostis plana, Sporobolus africanus and Themeda triandra. When the DM yield of all the grasses was combined, the results showed a generally low forage dry matter yield during the dry season. There was no significant (P>0.05) interaction between any of the main factors. Macro and micro mineral content of plant samples collected from the two communal grazing lands showed great variations (P<0.05) between species, seasons and altitude. In the Highveld, CP ranged from 3.9 to 6.5% DM being significantly highest (P<0.05) in Cynodon dactylon and lowest in E. plana. When all species were combined, higher CP was recorded for samples harvested in summer (5.5%) followed by spring and autumn, and lowest in winter (3.8%). In the Lowveld, Eragrostis chloromelus had higher (P<0.05) CP level followed by C. dactylon and T. Triandra. When all species were pooled, forage samples harvested in summer had a significantly higher (P<0.05) CP followed by spring, autumn and winter. In summary, CP content of all grasses was below the critical maintenance level for livestock especially during late dry seasons. In both areas, the highest NDF level was measured for Eragrostis plana and lowest for Themeda triandra. As for altitudinal differences, samples collected from the upland areas had generally the lowest (P<0.05) CP and highest ADF contents. For grasses harvested from the Highveld, C. dactylon produced the most (P<0.05) gas after 48 h of fermentation (794.6 ml/g DM) and also had the highest 48h DMD (415.1 g kg-1). Themeda triandra produced least (P<0.05) gas (742 ml/g DM) 48h post-incubation. The least (P<0.05) degradable species after 48 h was E. chloromelus (372.9 g kg-1). For grasses harvested from Lowveld, the 48h cumulative gas production was highest (822.7 ml/g DM) in E. plana and lowest (742.8 ml/g DM) in E. chloromelus, while S. africanus had least 48h DMD (327.9 kg-1). In both the Highveld and Lowveld, gas production and DMD were highest in the autumn season. It was concluded most grasses were deficient in calcium, magnesium, phosphorus and potassium. Therefore, it is recommended that mineral supplements should be offered to animals to improve animal productivity throughout the year. Findings of this study suggested that addition of protein and energy sources may be desirable in both grazing areas to meet the maintenance/production requirements of the grazing ruminants throughout the year. Key words: Forage yield, chemical composition, landscape gradient; seasonal variations; in vitro ruminal gas production; dry matter degradability.

- Description: This dissertation focuses on the microstructural and analytical characterization of plasma dissociated zircon (PDZ) which was produced by the South African Nuclear Energy Corporation (NECSA). The techniques used in the analysis of the material include scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy and wavelength dispersive X-ray spectrometry (EDS and WDS), infrared spectroscopy, Raman spectroscopy and X-ray diffraction (XRD). The differences in morphology of the zirconia (ZrO2) crystals observed in the PDZ are related to the thermal history of the material. Large zirconia crystals grow in a spherulitic manner and have the monoclinic crystal structure. Some smaller crystals formed via a rapid cooling process appear to retain the tetragonal or cubic crystal structures rather than relaxing to the monoclinic structure, and this may be because such nanocrystals are stabilised by small surface area or constraints from surrounding materials. Impurity distribution analysis of the PDZ showed that majority of the impurities present in zircon segregates to the silica phase during the dissociation process. The infrared and Raman spectroscopy analysis of the PDZ material indicated that the zirconia is present in the monoclinic and tetragonal polymorphs. X-ray diffraction revealed the presence of monoclinic, tetragonal and cubic zirconia phases. Rietveld refinement of the XRD patterns revealed zirconia to be predominantly found in the monoclinic polymorph followed by the tetragonal and cubic polymorphs. A Fourier transform infrared (FTIR) spectrometer equipped with an attenuated total reflectance (ATR) cell proved to be a viable method for determining the percentage dissociated zircon in PDZ.

- Description: The purpose of this study was to investigate and document parental involvement in a San community in Namibia over a period of two months. The emphasis was to investigate whether San parents in the Omusati region were involved in the learning of mathematics of their children. The learner participants were selected according to those who were open to sharing their ideas. An interpretive approach was used to collect and analyse data. The collected data was gathered from 9 participants (4 learners in grade 5 together with their parents, plus their mathematics teacher). Semi-structured interviews, parental contributions and home visit observations were the three tools that I used to collect data. The selected school is located in a rural area in the Omusati region of northern Namibia. The interviews were conducted in Oshiwambo (the participants‟ mother tongue) and translated into English and then analyzed. I discovered that the selected San parents were involved in some but limited school activities. The findings of this study emphasizes that illiteracy may be one of the contributing factors of low or non-involvement of parents among the San community. Other factors which I found caused parents not to assist their children with homework was parents spending much of their time at the local cuca shops during the day until late in the evenings. The study also highlights possible strategies that can be carried out by teachers to encourage parental involvement in school activities.

The findings of this study emphasizes that illiteracy may be one of the contributing factors of low or non-involvement of parents among the San community. Other factors which I found caused parents not to assist their children with homework was parents spending much of their time at the local cuca shops during the day until late in the evenings. The study also highlights possible strategies that can be carried out by teachers to encourage parental involvement in school activities.

- Description: The aim of the study was to explore and describe causes of re-offending and the management’s perspective of the effectiveness of programmes being implemented at Nerina One Stop Youth Justice Centre in dealing with re-offenders. Youth re-offending involves breaking of the law and crime. Offending if repeated then develops to be re-offending which is the breaking of the law more than once and this is a dilemma in South Africa as the increase of crime is a challenging issue. A qualitative approach was utilized following an exploratory, descriptive research design as the researcher sought to understand the perspective of the managers at Nerina regarding causes of re-offending and the effectiveness of the intervention programmes aimed at addressing this phenomenon. The researcher conducted face to face interviews with the mangers at Nerina One Stop Youth Justice Centre. For the purpose of this study the population was the total complement of the management staff at the One Stop Youth Justice Centre, this included the personnel of the departments of Justice, Social Development, and South African Police Service who are all involved in rendering services at Nerina. The method of data collection was one on one semi structured interviews and data analysis undertaken according to the steps for qualitative data analysis as proposed by Tesch in Creswell (1994). Guba’s model (Krefting, 1991) was employed for assessing the trustworthiness of the qualitative data. Some of the important findings included the causes of re-offending which included loss of parents, alcohol and drug abuse, inadequate parent role, role of peers and inadequate facilities. Further more from the study suggestions for improving programmes at the One Stop Youth Justice Center were discussed and these include involvement of community, involve more role players, training staff and increasing staff.

- Description: After the introduction of the Basic Education Teacher Diploma (BETD) in Namibia, a number of studies were conducted on how teachers, lecturers, stakeholders and the Namibian public perceived the BETD program and its implementation. However, very few studies focussed specifically on mathematics subject content knowledge and pedagogical content knowledge in the BETD. The purpose of this study was to investigate the need for a complementary course in mathematics education to address the lack of mathematical content and pedagogical knowledge in the Namibian BETD. The study involved five mathematics school teachers, two mathematics college lecturers in the Kavango educational region and a professor of mathematics education at the University of Namibia. These participants were purposefully selected because of their knowledge and experiences with various aspects of the BETD program. The motivation for conducting this study was to gain a better understanding of some of the issues that have been raised about the BETD program, particularly the perceived inadequacy of mathematical subject content and methodology since the inception of the program. The study adopts a qualitative approach in reporting participants’ reflections. The views of the focal educators and documents such as syllabi and course outlines were the main source of data. The findings indicate that despite the training that the three BETD mathematics graduates in this study received, the level of mathematics taught in a complementary course, such as an ACE, would clearly better equip mathematics teachers to teach proficiently and facilitate access to institutions of higher learning such as universities. The results of the study revealed that there was a need for the implementation of a complementary course to the BETD in mathematics education for teachers of mathematics in Namibia. This study also provided valuable insights into what such a course could look like.

An investigation into the popularity of American action movies shown in informal video houses in Addis Ababa, Ethiopia

- Description: The early 1990s saw a major change in the Ethiopian history in so far as Ethiopian media consumption practices was concerned. With the change of government in 1991, the ‘Iron Curtail’ prohibiting the dissemination of Western symbolic products within the country was lifted which in turn led to a surge in demand for Western predominantly American media texts. In order to supply this new demand, informal video houses showing primarily American action movies were opened in Addis Ababa. There was a significant shift in Ethiopians’ films consumption practices which were previously limited to watching films produced by socialist countries mainly the former Soviet Union. This study set out to probe reasons for the attraction of American action movies shown in video-viewing houses in Addis Ababa, Ethiopia amongst the urban unemployed male youth. Particularly, it examines how the meanings produced by and embedded in the cultural industries of the West are appropriated in the day-to-day lives of the youth. The importance of video houses as a shared male cultural space for Ethiopian unemployed youth and the watching of American action movies in this space are the main entry and focus of this study. Using qualitative methods such as observation, in-depth interviews and focus group discussions, the study explores what happens in this cultural space and how one makes sense of the impact of American media on local audiences. The findings of the study point to the embeddedness of viewing practice in everyday life and the importance of local contexts in understanding text-reader interaction. This is shown by the male youth’s tendency to use media messages as a mode of escape and a symbolic distancing from their lived impoverished reality. The study also seeks to highlight that the video houses as cultural space have contributed to the creation of marginal male youth identities in the Ethiopian patriarchal society. As such, these and other findings, the study argues, highlight the deficiencies of the media imperialism thesis with its definitive claims for cultural homogenisation as effect of globalisation of media. As such, this study should be read as emphasising the capability of local audience groups in Third World country like Ethiopia to construct their own meanings and thus their own local cultures and identities, even in the face of their virtually complete dependence on the image flows distributed by the transnational culture industries.

- Description: Organisations today, regardless of their function, exist in an environment that is characterised by change. In order to maintain a competitive advantage it is vital that organisations manage such change and are sensitive to their human resource. It is imperative for organisations to understand and explore the factors that impact on employee satisfaction and overall organisational performance. The hospitality industry is an industry that is notorious for low levels of pay and long working hours, and often dissatisfied employees. This research focused on a hotel, that is part of an international chain of hotels, which has recently undergone a rebranding process (a change from within). This research aimed to assess and explore factors that impact on levels of employee satisfaction and organisation/hotel performance, in other words it aimed to 'diagnose' the hotel's current status. The research was conducted in two phases. Phase one made use of a widely used measure of job satisfaction, the job descriptive index (JDI), that looked at five facets of job satisfaction namely: pay, opportunity for promotion, co-workers, supervision and the nature of work. Phase two further explored the results of the JDI (staff being very dissatisfied with pay and promotions opportunity) and further explored other areas of the organisation/hotel with the use of an organisational development model, Weisbord's Six-Box Model (1990). The 'boxes' included areas of purpose, structure, relationships, leadership, rewards and helpful mechanisms. These areas were explored with staff using focus groups. Heads of departments (management) and the deputy general manager of the hotel were interviewed using a semi-structured interview format, exploring similar issues to those researched with staff. Results indicated problems in the hotel with regard to purpose, a severe lack of communication and staff feeling they have little chance for promotion as well as pay structures being perceived as unfair. The overall leadership at the hotel was described as erratic, and relationships between management revealed high levels of mistrust. Due to limited research in the South African hospitality industry, much of the literature available is based on experiences in the United States of America or the United Kingdom. For this research, the researcher had few previous published findings and was unsure of the many issues that could possibly arise. However, the intervention was enjoyable and recommendations have been provided for the hotel to consider, so the hotel can go from "good to great".

- Description: This study was conducted to establish whether risk management strategies could be developed to enable stock market investment portfolio managers to reduce the risk involved in stock market trading. The awareness of stock market risk elevates the requirement for risk management strategies as discussed in Chapter 1. The research scope is identified, and an overview of the study gives further guidance as to what lies ahead. The theory behind macroeconomic forces and how they influence share prices is discussed in Chapter 2. It is established that market sectors and companies within those sectors react differently to macroeconomic forces. Technical analysis is discussed as a mechanism to identify buying and selling signals. In Chapter 3, risk management strategies are developed from the literature. The hypothesis of the study as described in Chapter 4 is that these risk management strategies are able to reduce the risk associated with trading in the stock market. The market simulation in Chapter 5 offers the opportunity to observe the risk management strategies at work in a simulated stock market investment portfolio. In Chapter 6, the outcome of the market simulation is compared to the criteria set in Chapter 4, and the conclusion that the risk management strategies were able to reduce the risk involved in stock market trading is drawn.

- Description: This research study was conducted in an attempt to explore the experience of multicultural communication within a South African organization. To this end employees, representing both Black and White culture, within a South African organization in the throes of transformation, were accessed. A model of managing diversity, focussing on the personal, interpersonal and organizational levels, was utilized in an attempt to uncover the nature of the experience of multi-cultural communication within Company X. A qualitative research design, and more specifically the case study method was employed in this study. Consistent with the case study approach a number of data sources were accessed. The primary data source consisted of a 3-stage interview process. Other data sources included documentary sources and company publications. By accessing multiple data sources, the researcher attempted to gain a holistic understanding of the experience of multi-cultural communication. It was found that the societal context of our post-Apartheid society exercises a profound influence on multi-cultural communication. Under Apartheid cultural separation was promoted. Diverse peoples thus have little common basis for interaction and view each other with skepticism and distrust. This exercises an effect on the personal and organizational levels of the managing diversity model. Influences at the personal level relate to the cultural paradigms of the individuals which provide the rules governing interactions and affect judgements of acceptable and unacceptable behaviours. Issues at the organizational level relate to its structures and policies which are still based on the “white is right ideology”. These issues, in turn, affect the interpersonal level of managing diversity, i.e., where the interactions occur, causing “communication short circuits” within the process of multi-cultural communication. In order to deal with failed multi-cultural communication, the individuals have developed a number of coping strategies. The results of the study indicate that both the organization and its employees share a responsibility for creating an environment that will facilitate effective multi-cultural communication.

A critical review of contemporary dance/movement therapy

- Description: This critical review aims to describe and define the field of dance/movement therapy. Attention is paid to central issues in psychology and dance studies which influence the advancement of the modality. Dance/movement therapy is a young profession, developed during the second half of this century, and must be viewed within the socio-cultural context of contemporary western industrialized societies. This work therefore firstly documents the development of dance/movement therapy in the light of recent studies into the nature of bodily expression and non-verbal communication. The phenomenological understanding of the human body is discussed, and the concept of bodyliness proposed in order to encapsulate a multi-dimensional understanding of the meanings of the human body. Dance/movement therapy is then delineated in relation to verbal psychotherapeutic traditions, as well as to the more marginalized body therapies. In this way it is hoped to provide an understanding of the historical precedents and theoretical contexts within which dance/movement therapy is emerging, and ultimately the possibly unique alternative service it may provide. As wide a variety as possible of theoretical approaches in dance/movement therapy is then described, and classified according to the predominant psychological orientation of the proponents. From this a critical review is attempted which is directed broadly at foundational considerations of the profession, rather than at any particular methodology. The enquiry focusses on directions for future possible research which will ensure sound theoretical frames of reference for the developing profession. Discussion of two examples of dance being used in the therapeutic context in South Africa concludes. This section is not a judgmental evaluation of techniques, but intended rather as documentation and broad classification of current work of this nature.

The spawning and grading techniques which resulted in a higher fecundity and ensured uniformity within and between samples of fry are discussed. Preparation techniques were developed which met the physical requirements of fry feeds. An analysis of the flesh and yolk sac fry for amino acid composition was undertaken. The initial test diet was based on these results, as well as on the natural feeding ecology of the species. Feeding trials were undertaken and growth responses monitored to determine the optimum levels of the various dietary components. A feed was developed which gave superior growth to that obtained with natural food organisms. This feed consisted of Torula yeast (47%), Weider Super Protein (44.39%), Vitamin supplement (0.45% - multivitamin), additional vitamin C supplement (0.16%), Spirulina (5%), and methionine supplement (3%). An optimum particle size range for O. mossambicus fry (between 5 & 25mm) was established at 125-200um. The fry should be fed the following feed ratios depending on age: 30.4% body weight/day up to day 5, 30.6% body weight/day up to day 10 and 25.1% body weight/day up to day 15. An optimum feeding frequency of 8/10hr day was recommended. A feed conversion ratio of 1.24:1 and a protein efficiency ratio of 0.682:1 was obtained. Digestable energy of the feed was determined at 16.1 kj/g feed. The established dry feed is suitable for use in commercial hatcheries, and as a formulation for further research on the intensive rearing of O. mossambicus fry.

- Description: Various notions of compactness in a fuzzy topological space have been introduced by different authors. The aim of this thesis is to compare them. We find that in a T₂ space (in the sense that no fuzzy net converges to two fuzzy points with different supports) all these notions are equivalent for the whole space. Furthermore, for N-compactness and f-compactness (being the only notions that are defined for an arbitrary fuzzy subset) we have equivalence under a stronger condition, namely, a T₂ space in the sense that every prime prefilter has an adherence that is non-zero in at most one point

- Description: Mo became very important in the last century, because of its sophisticated properties and its use in the new technology of alloys . Porphyry systems (porphyry Cu-Mo and Mo) contribute a significant proportion (90 - 95 per cent) to the Mo world's production. This type of deposit is associated mainly with Phanerozoic orogenic belts. Above 87per cent of the world resources are in the American Circumpacific belts , both Andean and Cordilleran . Ore grade in porphyry Cu-Mo range from 0,005 to 0,04per cent Mo, whereas in porphyry Mo grades range from 0,08 to 0,75per cent Mo . These deposits are associated with a magmatism which shows an evolution from calcic in island arcs, to calc-alkaline in magmatic back arcs, with an increase of the Mo content in the same direction. Porphyry Mo deposits display several features in common with porphyry Cu deposits. hydrothermal Similarities include nature of host alteration patterns and distribution of rock intrusives, ore minerals. An interesting difference is found in the Re contents of the molybdenite mineral. This element is higher in the molybdenites of porphyry Cu, than in those of the porphyry Mo. The ore genesis process begins involves partial melting, within enriched zones of the upper mantle and magma differentation, liquid state thermogravitational diffusion, magma convection and boiling. These processes progressively concentrate Mo in the fluids, which are released at some stage, into sulphidic hydrothermal systems, under complex geologictectonic conditions involving fracturing, brecciation and hydrothermal alteration. Major concentrations of the ore mineral are always associated with potassic alteration, and with late magmatic-early hydrothermal stages (Chilean and Western North American porphyries). Geological mapping and a close understanding of alteration and mineralization patterns, and lithogeochemistry are important tools for the exploration of porphyry Mo deposits. Geochemical prospecting, using soils, vegetation and water as sampling media, and regional aeromagnetic, gravity surveys, aerial photography and remote sensing, are us.

Turbidite-hosted gold deposits

- Description: Turbidite-hosted gold deposits contribute a significant proportion to world lode gold production and have also provided substantial gold to alluvial resources. Turbidity current deposits occur throughout geological time within Archaean greenstone belts, Proterozoic orogenic belts and rifted passive continental margins, and Palaeozoic geosynclines. Representing the end member of the sedimentary cycle, turbidites have the attribute of preservation not only on an individual bed basis but also due to below wave base accumulation in submarine deeps. Cyclic deposition according to the Bouma sequence punctuates turbidite deposition by a series of diastems. Accumulation of organic, pelagic and chemical sediments may concentrate gold to protore enrichment levels i n a primary sedimentary environment. Dewatering during diagenesis and low-grade metamorphism under reducing conditions may redistribute gold with transport as low energy organo- and thio-complexes. Gold may precipitate with diagenetic pyrite and silica near black shale and/or partially replace fine carbonate detritus. Gold solubility increases with high grade amphibolite facies metamorphism (T 400ºC) when efficient leaching of gold and transport by simple chloro- and hydroxychloro - complexes to lower greenschist regions takes place. Reduced permeability of turbidite strata induces hydrofracturing which focuses dewatering solutions. Gold is deposited due to pressure and temperature decrease or local changes in physico - chemico conditions caused by the reaction of fluids with wall rocks (reactive beds in turbidites are predominantly carbonaceous strata). The largest of turbidite - hosted goldfields are confined to back -arc or marginal sea basins with restricted oceanic circulation. The richest concentrations of gold occur proximal to the original source within the greenschist facies formations lowermost in a thick turbidite sequence and exhibit strong combined structural and lithological association. Turbidites represent important strata for the concentration and preservation of gold not only during sedimentation and diagenesis but also during later deformation and metamorphism.
