White writers and Shaka Zulu

- Description: The figure of Shaka (c. 1780-1828) looms massively in the historical and symbolic landscapes of Southern Africa. He has been unquestioningly credited, in varying degrees, with creating the Zulu nation, murderous bloodlust, and military genius, so launching waves of violence across the subcontinent (the "mfecane"). The empirical evidence for this is slight and controversial. More importantly, however, Shaka has attained a mythical reputation on which not only Zulu self-conceptions, but to a significant degree white settler self-identifications have been built. This study describes as comprehensively as possible the genealogy of white Shakan literature, including eyewitness accounts, histories, fictions and poetry. The study argues that the vast majority of these works are characterised by a high degree of incestuous borrowing from one another, and by processes of mythologising catering primarily to the social-psychological needs of the writers. So coherent is this genealogy that the formation of an idealised notion of settler identity can be discerned, especially through the common use of particular textual "gestures". At the same time, while conforming largely to unquestioning modes of discourse such as popularised history and romance fiction, individual writers have attempted to adjust to socio-political circumstances; this study includes four close studies of individual texts. Such close stylistic attention serves to underline the textually-constructed nature of both the figure of Shaka and the "selves" of the writers. The study makes no attempt to reduce its explorations to a single Grand Unified Explanation, and takes eclectic theoretical positions, but it does seek throughout to explore the social-psychological meanings of textual productions of Shaka - in short, to explore the question, Why have white writers written about Shaka in these particular ways?

Technologies of the self in the writings of William S Burroughs

- Description: William Burroughs's profane life has been an affront to conventional morality, and his transgressive works have strained against the thematic and formal boundaries of literature. Although he has remained a problematic figure, he is gradually gaining recognition as a literary innovator. This thesis argues that his writings may be understood as technologies of the self, that is, the texts are tools that the writer Oses to transform himself. The Introduction outlines the problems that his writings pose for criticism; provides an overview of critical responses to his work; and demonstrates the appropriateness of Michel Foucault's theory of the technologies of the self as an approach to his texts. Furthermore, it makes a comparison between Burroughs's concerns and similar concerns evident in Foucault. The most prominent of these is a fear of control, and a desire to escape from control. It is argued that this similarity arises from the writers' shared experience of homosexuality in the twentieth century. This experience provokes them to undertake a·work of homographesis, in which they attempt to undermine the construction of identity in text, whilst simultaneously reinscribing identity in problematized autobiographical writing. Chapter One provides a corrective to the critical neglect of Burroughs's homosexuality and focuses on his sexual problematic as a key factor in the development of his literary style. It argues that the writer has an abject imagination that was precipitated by three principal traumatic experiences: his homosexuality, his addiction to opiates, and the accidental shooting of his wife. The chapter examines the way that the writer develops his unique literary style, the routine, in an attempt to express his psychic disintegration. The routine becomes the basic building block of Naked Lunch, serving both as a cathartic release of psychic anguish and as an attempt to subvert repressive social and linguistic structures. The metaphor of the anal aesthetic is introduced to describe the intersection of linguistic, psychic and political strategies in the texts. Chapter Two addresses the period,subsequent to Naked Lunch, in which Burroughs experimented extensively with the cut-up technique to develop a form of aleatory collage. The chapter argues that the writer hoped that the technique would enable him to transform himself and to~discover a new way of thinking, but suggests that its extreme nature both isolated him from his audience and intensified his psychic abjection. Chapter Three follows on from this to argue that the writer responds to the limitations of the cut-up in The Wild Boys by returning to a more intelligible form of writing. This return corresponds with an attempt to inscribe homosexual themes into his work directly. However, the combination of a homosexual agenda and the writer's defence against the identity loss of abjection leads him to assert a radical masculine identity that causes him to perceive women as the chief perpetrators of control. As a result, he rejects women from his mythological system. Chapter Four suggests that in Cities of the Red Night and The Place of Dead Roads the writer moves away from the radical queer agenda of The Wild Boys in the hope of discovering a form of ethics that avoids the traps of universalized humanism and the harsh "othering" of the queer agenda. The chapter draws a parallel between Burroughs's individualized ethics and Foucault's idea of an ethics grounded in aesthetic self-fashioning. Chapter Five examines The Western Lands, in which the writer confronts death in order to discover the nature of individual value in a normalized culture. Like Foucault, Burroughs believes that the most important task in a limited existence is the dandyistic creation of the self.

- Description: Progress in South African estuarine ichthyology between 1946 and 1995 is reviewed. The early estuary surveys of the 1950s and 1960s resulted in the compilation of species lists for individual systems, but contained very little biological or ecological information on fishes. These surveys were superseded by both autecological and synecological studies in the 1970s and 1980s, which yielded descriptive and process-orientated information on a wide variety of species. Estuarine research during the 1990s has focused increasingly at the community level, with several review papers on the life-history styles of groups of estuarine-associated fishes being published. The last decade has also seen the departure of a number of senior estuarine ichthyologists from the field. This decline in available expertise has coincided with increased demand for ichthyological information to be used in decision support systems for the wise management and conservation of estuaries. It is suggested that these demands be seen as a challenge, with studies being directed towards providing the type of information needed for the maintenance of vital ecological processes within these systems.

Anaesthesia in abalone, Haliotis midae

- Description: The principle aim of this study was to isolate a chemical for the "safe anaesthesia" of abalone under commercial farming conditions. "Safe anaesthesia" implied that the anaesthetic had no immediate detrimental or long term sublethal effect on the abalone, that it was safe for the farmer, the consumer and the environment. Four chemicals, magnesium sulphate (MgS0₄), ethylenediamine tetra-acetic acid (EDTA), 2-phenoxyethanol and procaine hydrochloride were shown to effectively inhibit the in vitro contraction of isolated tarsal muscle of Haliotis midae. This identified them as potential anaesthetics for abalone. Since abalone, like any other aquaculture species, would be subject to frequent size-sorting during the grow-out period, size related dosage tables were developed for the four chemicals at a temperature of 18⁰C. Dosage tables were also developed for benzocaine and carbon dioxide (C0₂), Three size classes (5-15, 20-50 and 60-90 mm shell length (SL)) of abalone were considered. Only three of the six chemicals, viz. MgS0₄, 2-phenoxyethanol and CO₂, met the criteria of an effective abalone anaesthetic in that they effected rapid and mortality-free anaesthesia. The other three chemicals caused mortalities and were considered to be unsuitable for commercial scale anaesthesia. Temperature related dosage tables were then developed for MgS0₄ and CO₂, MgS0₄ concentrations and CO₂ flow rates for effective anaesthesia in abalone were found to be inversely related to temperature. The three size classes of H. midae were intermittently exposed to MgS0₄ and 2-phenoxyethanol anaesthesia for an eight month period to determine the effect of the anaesthetics on growth rate. Because of an increased resistance to the efficacy of 2-phenoxyethanol and high monthly mortalities it was concluded that this chemical was unsafe and unsuitable for commercial use. MgS0₄, on the other hand, had no effect on growth of abalone and no significant effect on the rate of mortality. MgS0₄ also had no measurable effect on H. midae muscle ultrastructure and, by implication had no effect on flesh texture. The use of MgS0₄ as an anaesthetic would, therefore, not affect marketability. Moreover, no magnesium residues were found in H. midae muscle tissue after short term or intermittent long term exposure to MgS0₄ anaesthesia. It was found that the three size classes of H. midae used in this study could be safely exposed to the recommended MgS0₄ concentrations for up to 40 minutes without any mortalities. This is more than adequate for routine farming procedures. Medium size abalone (20-50 mm SL) were also safely exposed to 14 g.100 ml⁻¹ MgS0₄ for up to 6 hours without any mortalities. The results have shown that MgS0₄ was undoubtedly the best chemical that was evaluated for anaesthesia of H. midae in this study. It fulfils the requirements set forth by the U.S.A. Food and Drug Administration (FDA) in that it is safe for the abalone, the farmer, the consumer and the environment.

- Description: Digital geographical information systems (GIS) are tools for handling spatial data. Initially developed in First World countries, the technology is fast being taken up as a tool for handling spatial information by many Third World countries. GIS has been used for any number of applications involving spatial data, one of its primary uses has been in various planning fields where the advantages offered to planners by the technology have been highlighted by a number of publications and studies. GIS has been actively used as an urban planning tool in South Africa since the mid-1980s, (Vosloo 1987) however its use as a tool for rural planning has not developed to the same extent. As early as 1986 reference was made to the possible advantages offered by GIS to rural planning in South Africa (Fincham 1986). Despite this early recognition, the use of GIS in the rural planning sphere remains negligible. This study examines the. possible reasons for this by attempting to answer the question, "is GIS appropriate to rural planning in South Africa?" A number of approaches to rural planning are practised in South Africa. This study examines the appropriateness of applying GIS to one of these approaches, rural community development planning. Components of the study included i) an examination of the issues affecting the use of GIS in the rural development field, achieved through the use of a literature and questionnaire survey and ii) a case study examining the feasibility of incorporating GIS as a tool to the Shixini Development Project, Transkei. The study does not examine the intricacies of rural development theory, but it does acknowledge the fact that the approach employed by an organisation to rural development will have important implications concerning the use of a GIS in a project. The approach adopted to a project affects amongst others the administrative structure, the planning process, the flow of spatial data and its use, and consequently the possible role of GIS. The Shixini Rural Development Project was classified as a community development project, and as a result the study concentrates on this approach to rural development. This may limit the study to a particular planning process, however most rural case studies will have certain aims and factors which are unique to its situation. In order to place the results of the Shixini case study in a wider context the results of the study are linked to the questionnaire and literature survey. From this basis the usefulness of GIS in the rural development sphere was examined. Available literature on GIS indicates that the majority of problems associated with GIS rarely reside with the technology itself but rather with its supporting mechanisms. The study identified and concentrated on these support mechanisms, both at the project level and what is referred to in the study as the operating environment in South Africa. The results of the study revealed that a number of problems exist with regard to the attitude with which GIS is regarded in development organisations. It was found that these attitudes are legitimately based on a number of problems associated with incorporating the technology into project based organisations. It was concluded that GIS was appropriate to rural community planning, but is presently limited to certain aspects of the planning process and possibly to certain applications.

- Description: The central aim of this study was to explore the meaning of death as both a literal and an imaginative reality, and to elucidate the fundamental tensions between these meanings of death in modern existence. Recognition was given to the need for a poetic rather than a scientific approach to thanatology, and an epistemological foundation for a poetics of death was sought in the tradition of gnosis. Theoretically, the study was grounded in the analytical psychology of C.G. Jung. It was argued that despite Jung's erratic allegiance to a Cartesian ontology and epistemology, his approach to death was nevertheless fundamentally poetic. The poetic parameters of death and dying were explored in the context of Jung's understanding of the dialectical tension between the ego and the self, and it was concluded that while death represents an opening to the imaginative possibilities of existence, these potentialities can come to the fore only when there is a corresponding willingness to die. In these terms, it was concluded that the tension between life and death forms a pivotal dynamic of human existence. These considerations led to the Question of whether the poetic parameters of death and dying are applicable to the encounter with death as a concrete actuality. It was hypothesised that the approach of death would be met at two levels of reality, that of the ego and that of the self. The expectation was that while death would be seen as a literal ending from the perspective of the former, it may represent the fulfilment of Being from the viewpoint of the self. It was also assumed that the tension between these images of death would be mediated by way of archetypal symbols, which represent the bearers of gnosis in modern culture. To address these issues at an empirical level, a hermeneutically grounded thematic analysis of 108 dreams reported by dying persons was undertaken. Twenty initial themes emerged from the data. Each of these themes was in turn elucidated by way of Jung's method of amplification. This exercise yielded five concise themes, these being (a) death, (b) transformation, (c) the self (d) the Feminine, and (e) the Masculine. It was concluded that dreams manifesting during the dying process reveal a fundamental tension between literal and metaphoric possibilities of death. Dream symbols were also found to mediate between this tension, and to orchestrate the individuation process. It was concluded that in the context of dying, dreams may reflect and facilitate the emergence of a meaningful gnosis of death. The clinical implications of these findings were onsidered, and indications for further research were provided.

To address these issues at an empirical level, a hermeneutically grounded thematic analysis of 108 dreams reported by dying persons was undertaken. Twenty initial themes emerged from the data. Each of these themes was in turn elucidated by way of Jung's method of amplification. This exercise yielded five concise themes, these being (a) death, (b) transformation, (c) the self (d) the Feminine, and (e) the Masculine. It was concluded that dreams manifesting during the dying process reveal a fundamental tension between literal and metaphoric possibilities of death. Dream symbols were also found to mediate between this tension, and to orchestrate the individuation process. It was concluded that in the context of dying, dreams may reflect and facilitate the emergence of a meaningful gnosis of death. The clinical implications of these findings were onsidered, and indications for further research were provided.

- Description: The Phongolo River floodplain in KwaZulu/Natal is a river-associated wetland which was subject to regular cycles of flooding in the past. The floods were associated with seasonal summer rainfall. Through the wet and dry cycles on the floodplain there was an alternation between the aquatic and terrestrial biomes. Many of the fishes on the floodplain are dependent on this cycle for their survival. The construction of the Pongolapoort Dam in 1969 has resulted in alterations to the timing, magnitudes and duration of the natural flooding events of the Phongolo River. This alteration has affected the fisheries. It is now necessary to simulate natural floods by artificial water releases from the dam. There are several demands on the water supply, so it has not always been possible to adhere to the natural flood regime. This necessitated the need for an integrated management programme to ensure the sustainability of the natural resources. A practical ecological model of the fishery was developed to determine an optimum flood release scenario for the floodplain. The relative abundances, distribution and species richness of the fishes were determined at various lakes and rivers on the floodplain. A community classification of the fishes was determined using TWINSPAN ordination. The potential yield of the fish at each site was calculated. Flood releases of varying magnitudes were simulated using Geographic Information Systems (GIS). This information was combined in a model which can be used by resource managers to estimate the percentage species compositions of fishes at each of the lakes, and to compare the actual harvest to the potential calculated sustainable yields of fishes for various flood release regimes. Subsistence agriculture and other beneficial ecological information can be incorporated into the model to determine the effect of different flood release options for the Phongolo floodplain.

In certain cases suppositories are the best form of therapy, or else they are an effective alternative when oral therapy is not possible. However; doctors rarely prescribe them and patients are often reluctant to use them. Understanding how suppositories work, and their numerous uses, can overcome the aversion to this particular dosage form. Pharmacists are in an ideal position to educate doctors, other health care providers, and patients, on the benefits of using suppositories and their correct use, and to offer advice on any problems associated with their use.

- Description: It is clear that scientists are now only beginning to comprehend the complexity of transdermal drug delivery. Elucidation of the biochemical composition and functioning of the intrinsic diffusional barrier of the stratum corneum has prompted investigation of chemical and physical means of enhancing the percutaneous penetration of poorly absorbed drugs. Chemical enhancers that aid absorption of co-administered moieties are currently believed to improve solubility within the stratum corneum or increase lipid fluidity of the intracellular bilayers. Alternatively,the use of ionto- or phonophoresis may facilitate the absorption of some drug molecules by physical alteration of the barrier. The role of penetration enhancer inclusion in topical formulations has been well documented and will undoubtedly, in the future, permit the delivery of broader classes of drugs through the stratum corneum.

- Description: The combined potential of two crucial factors in 1993, which afforded the promotion of socially just and ecologically sustainable ways of living, led to the instigation of this research project. The first was the imminence og our first democratic election; the second was the possible introduction of environmental education into formal education. In the light of these momentous shifts, it became apparent to me that teachers would have to radically transform their practices in order to play their part in transforming society from the dark days of apartheid into one of equity and harmony. The implications of these factors precipitated the falling into place of the rationale for my research: teachers had to look for professional development experiences which could facilitate the creation of alternative ways of thinking and doing. As a result, I approached a group of biology and geography teachers on the Cape Flats and, after protracted discussions, we decided to examine the potential of the urban environment for the teaching of ecology from the perspective of socially just and environmentally sustainable living. Out of this decision was born this study, which aimed at examining whether this process could, as a means to professional development, be a 'moment' in our journey to becoming transformative intellectuals. From this aim, the central research question emerged: Can emancipatory action research play a role in empowering teachers to become transformative intellectuals? The study consisted of five stages: - exploring the problem by reviewing the literature on the research problem; - the semi-structured interviews; - five workshops; - the 'sensing the urban environment' fieldtrip; and, - the various evaluation sessions. What we achieved during this research project, firstly, was a better understanding of our practices, which led us to seeing our roles as teachers differently and altered our pedagogical approaches. Secondly, this process developed the belief within ourselves that we, as teachers, can and should make a difference to the educational world in which we live. Lastly, this process laid the foundation for continued collaborative action by the participants. This process taught us that educational transformation is difficult and painful, and that present educational structures are not conducive to change. Nonetheless, in the historical context of this research, emancipatory action research was successful in giving us a consciousness-raising experience and closed the rhetoric-reality gap as we engaged in praxis (the practitioners developing and implementing their own curriculum). If we, as transformative intellectuals, are to engage in intellectual labour in the future, we are not only going to need to change our way of thinking and doing but will have to create an enabling infrastructure to realise this as well. We will, in addition, have to change the structures of the institutions in which we work in order to practise as transformative intellectuals.

- Description: This thesis develops a technique for the identification, classification and quantification of instream flow environments. These features have been traditionally referred to as 'habitats' by lotic ecologists, in this research they are termed 'hydraulic biotopes'. The hydraulic biotope is the lowest of six nested levels of a hierarchical geomorphological model. This model has been developed as a tool to assist river managers, researchers and conservationists to categorise or classify rivers with respect to their geomorphic characteristics. Each level of the model provides data at a different level of resolution. This ranges from the broad scale catchment data to the site specific 'habitat' or hydraulic biotope data. Although this thesis is primarily concerned with the development of the hydraulic biotope, the interaction of all catchment variables needs to be recognised. Detailed analysis of hydraulic biotope data in the Buffalo River are presented within the broader hierarchical model. Consultation with lotic ecologists, together with a review of ecological literature, emphasised the need for a standardised terminology for the classification of ecologically significant instream flow environments. At present a fairly haphazard 'habitat' classification tends to be carried out by most researchers, this often leads to confusion in the identification and naming of different hydraulic biotopes ('habitats'). This confusion is exaggerated by the sharing of terminology between lotic ecology and fluvial geomorphology, usually for the categorisation of different types of features. A review of the ecological literature emphasises the importance of flow hydraulics within a river to describe the distribution of biota. The hydraulic variables considered to be most significant include velocity and depth. As river morphology directly determines the prevailing distribution of depth, velocity and substratum, it is obvious that there are important links to be made between fluvial geomorphology and lotic ecology. This thesis explores the potential of the hydraulic biotope as a tool to help develop those links. This thesis presents a standardised classification matrix for the identification of hydraulic biotopes. The matrix is simply based on water surface characteristics together with channel bed substratum. The validity of this matrix is tested by statistical analysis of hydraulic variables quantifying flow conditions within the various hydraulic biotope classes. Data is presented from four different river systems, each representing a different sedimentological environment. Where possible the influence of discharge has been considered. Results from more than 3000 data points show that hydraulic biotopes have distinct hydraulic characteristics in terms of velocity-depth ratio, Froude number, Reynolds number, 'roughness' Reynolds number and shear velocity. These hydraulic indices represent flow conditions both as an average within the water column, and near the bed. Statistical analysis shows that the hydraulic characteristics of the various hydraulic biotope classes are relatively consistent both within different fluvial environments and at different stages of flow. Unlike the morphological unit in which the hydraulic biotope is nested, in stream flow environments are shown to be temporally dynamic. Using the classification matrix as a tool for identification, hydraulic biotopes identified at one discharge are shown to be transformed from one class to another as a response to change in stage. The pattern of transformation is shown to be consistent within different sedimentological environments. An examination of the associations between hydraulic biotopes and morphological units demonstrates that, although some hydraulic biotopes are common to all morphological units (backwater pools, pools and runs), some features have specific associations. In this study rapids were found to be prevalent in bedrock pavement, bedrock pool and plane bed morphology, while cascades, chutes and riffles were common to plane bed, step and riffle morphology. Results from this research indicate that the hydraulic biotope, within the hierarchical geomorphological model, has the potential to aid the prediction of channel adjustment and associated 'habitat' (hydraulic biotope) transformation in response to changes in flow and sediment yield. These are likely to become increasingly important issues as South Africa strives to maintain a balance between the development of water resources to meet the needs of the rapidly expanding population, whilst at the same time maintaining the fluvial environment for sustainable use.

- Description: The first aim of teaching English literature has always been for the student to gain enjoyment from, and acquire skill in, reading. Further goals point to the affective development of pupils involving such qualities as critical thinking and expressing views, empathetic understanding of other people, moral awareness and increased self-knowledge and self-understanding. These are indeed laudable aims, but examiners have always had difficulties in examining them adequately to satisfy the critics. Teachers often doubt that they achieve such lofty aims. These very aims have the sceptics sneering at the discipline because such qualities cannot be measured and the pupil's worth for the workplace cannot be satisfactorily assessed. This has resulted in the merit of the study of literature being questioned and usually found wanting. Therefore, on the one hand, this research looks for a method of studying literature which will ensure that the study will be neccesary and desirable today and into the foreseeable future. On the other hand, the socio-political changes in South Africa, particularly since 1992, have offered a possible area of research to complement the first. During the past few years, South Africans have been forced to recognise the fact that a multitude of different races and people live and work together more closely in this country and yet they know nothing, or very little, of one another. Thus this research also investigates the addition of a cultural component to literature study to help young people gain empathetic understanding of different cultures and of their own cultures as well, to be able to live together in harmony. With this approach, pupils may conceivably be educated through literature, to become well-adjusted, critical, effective adults so that they may play their role as citizens and shapers of their increasingly complex, multi-cultural society. Because of the context of literature study, in which this personal growth takes place, the aims identified above may be measured and assessed to suit both the sceptics and the devotees of literature study.

- Description: The reductions of WO₃ with hydrogen, with CO, and with carbon, as well as the reduction of WO₃/graphite mixtures with hydrogen, were studied using thermogravimetry, evolved gas analysis, X-ray powder diffraction, and scanning electron microscopy. The intermediate phases W₂₀O₅₈, W₁₈O₄₉ and WO₂, were observed in the reductions. The final product of the reductions with hydrogen and carbon was tungsten, and we was formed in the reduction with CO. The reaction paths in the overall processes were determined. The reactant/product gas ratio had a considerable influence on which reactions took place. The morphology of the sample was characterised at different stages of the reduction. The shape of the WO₃ particles was retained during the reduction. Particle growth was observed in the reduction with hydrogen and was attributed to the formation of WO₂(OH)₂(g). The kinetics of the reductions were investigated , and the reaction mechanisms determined. The reduction of WO₃ with CO was studied from 650 to 900°C, and occurred at a phase boundary with an activation energy of 40 kJ mol⁻¹ . The reduction of WO₂, was studied under the same conditions. The reaction also occurred at a phase boundary and had an activation energy of 62 kJ mol⁻¹. The reduction of WO₃ with carbon was studied from 935 to 1100°C and took place via CO and CO₂. Two stages were observed in the reduction . The first stage, which corresponded approximately to the formation of WO₂ had an activation energy of 66 kJ mol⁻¹ and was limited by diffusion through the porous reacting particles. The second stage was first order and had an activation energy of 40 kJ mol⁻¹. The reduction of WO₃ and WO₃ graphite mixtures with hydrogen were studied from 575 to 975 °C. The reactions were controlled by mass-transfer under the conditions investigated. The addition of carbon increased the rate of the reduction process , but did not affect the phases formed in the system. CO₂ was evolved mainly at the start, and CO mainly at the end of the process.

The reduction of WO₃ with CO was studied from 650 to 900°C, and occurred at a phase boundary with an activation energy of 40 kJ mol⁻¹ . The reduction of WO₂, was studied under the same conditions. The reaction also occurred at a phase boundary and had an activation energy of 62 kJ mol⁻¹. The reduction of WO₃ with carbon was studied from 935 to 1100°C and took place via CO and CO₂. Two stages were observed in the reduction . The first stage, which corresponded approximately to the formation of WO₂ had an activation energy of 66 kJ mol⁻¹ and was limited by diffusion through the porous reacting particles. The second stage was first order and had an activation energy of 40 kJ mol⁻¹. The reduction of WO₃ and WO₃ graphite mixtures with hydrogen were studied from 575 to 975 °C. The reactions were controlled by mass-transfer under the conditions investigated. The addition of carbon increased the rate of the reduction process , but did not affect the phases formed in the system. CO₂ was evolved mainly at the start, and CO mainly at the end of the process.

- Description: The Witwatersrand basin is unique in terms of its mineral wealth. The gold in the Witwatersrand basin is mainly concentrated in the placers and two types of unconformities are associated with the placer formation. This paper attempts to quantitatively describe the origin and depositional process of placers within the context of basin analysis, geohistory and sequences stratigraphic framework. Several tectonic models have been proposed for the evolution of the Witwater~rand basin and it seems as if a cratonic foreland basin accounts for many of the observed features observed the Central Rand Group basin. The tectonic subsidence curve generated for the Witwatersrand Basin clearly implies foreland basin response which was superimposed an older, deep seated extensional basin. These compressive tectonics can be superimposed on extensional basins, where the shift from extensional to compressional tectonics lead to inversion processes. The critical issues about the Witwatersrand basin which were addresed in this review, is the validity of basin wide correlation of placer unconformuties and whether sequence stratigraphy is applicable to fluvial systems of the Witwatersrand sequence. It is believed that the Central Rand Group was deposited as alluvial - fan deltas by fluvially dominated, braidplain systems with minor marine interaction which had a considerable impact on the preservation of economically viable placers. Most important to the exploration geologist is the recognition of stacking patterns of the fluvial strata to determine change in the rate at which accommodation was created. Identifying sequence boundaries and other relevant surfaces important for identifying these stacking patterns of the sequences, depends entirely on the recognition of a hierarchy of stratal units including beds, bedsets, parasequences, parasequence sets and the surfaces bounding sequences. Placers are closely associated with the development of disconformities and therefore become important to recognise in fluvial strata. If these placers are to become economic, the duration of subaerial exposure of the unconformities that allowed the placers to become reworked and concentrated must be determined. In order to preserve the placer, a sudden marine transgression is necessary to allow for minimal shoreline reworking and to cap the placer to prevent it from being dispersed. The placers in the Witwatersrand basin occur in four major gold-bearing placer zones in the Central Rand Group. Accordingly they can be assigned to four supercycles, which are cyclical and therefore predictive. It is the predictive nature of these rocks and the ability of sequence stratigraphy to enhance this aspect, which is a pre-requisite for an effective exploration tool in the search for new ore bodies or their extension in the Witwatersrand basin.
