Thesis submitted for the degree of Master of Science in the Faculty of Science, University of the Witwatersrand / A stratigraphic and sedimentological study of the Molteno sediments in the vicinity of Aliwal North and Burgersdorp was made in order to determine stratigraphic relationships and sedimentary history. The stratigraphic study shows that the Molteno strata is characterised by a cyclic pattern of deposition as follows: (i) pebble conglomerate overlying an erosional surface of low relief; (2) coarse - to medium- grained sandstone; (3) fine-grained sandstone~siltstone, and silty shale and (4)" shale with thin coal lenseso Three such cycles have been recognised in the Burgersdorp area and a single cycle at Aliwal North. The succession thins northwards from about 500 feet around Burgersdorp to 300 feet at Aliwal North and on the basis of cyclic relationships and sedimentary tectonics it is suggested that the two upper cycles at Aliwal North are missing through erosion or non-deposition and the lower cycle at Burgersdorp is the stratigraphic equivalent of the Aliwal North cycle. The importance of the lower pebble bed arises from the ease with which it can b e recognised and traced throughout the area; moreover, it is tectonically significant and represents a distinct stratigraphic break . As a result the base of the Molteno is redefined in terms of the lower pebble bed. The limitations of the Indwe sandstone as a regional stratigraphic marker are demonstrated. It is also recommended that the Indwe sandstone be more strictly defined in terms of modern stratigraphic nomenclature or dropped completely from the literature . The pattern of sedimentary transport was determined mainly from cross-bedding measurements, though other sedimentary structures such as erosion channels, ripple marks, current lineations, and fossil logs have also been used . These dimentary structures indicate shallow water conditions of deposition with the dominant direction of transport from the south and south east. The sandstones have been classified petrographically as subgreywackes. Metamorphic quartz and metaquartzite rock fragments together with minor amounts of feldspar are important constituents. Excluding micas the heavy mineral suite is simple and consists of garnet, zircon, tourmaline and rutile . The Molteno sediments wer e derived chiefly from high- rank metamorphic and granitic source rocks with only neglible contributions from pre - existing sediments . Integration of the stratigraphic and sedimentological evidence shows that the upward-fining cycle of the Molteno was deposited under both upper and lower flow regime conditions. Facies analysis of the cycle suggests that the conglomerate is the result of erosion and deposition in a braided river channel wandering across a flood plain. The overlying sandstone shows all the characteristics of a modern point bar complex. The fine sandstone, siltstone, and silty shale represent a transitional facies deposited mainly from suspension in the quiet parts of the channel or in abandoned channels during low water. If the sandstone facies represents channel deposits then the shale and coal facies probably records overbank deposits from flood waters in the quiet backswamp areas of the flood plain. The environment was probably permanently inundated by water of such a depth as to allow for the growth of plants and the formation of peat swamps. The key to cyclic repetition appears to be related to sedimentary tectonics and diastrophic movement associated with the second phase of the Cape Orogeny. In terms of sedimentary tectonics, and the classification scheme of Krumbein and Sloss (1963), the lithologic association of the Molteno sediments probably represents unstable shelf or interior basin conditions . / AC 2018

Thesis (MSc)--Stellenbosch University, 1989. / ENGLISH ABSTRACT: The Ceres Syntaxis comprises that part of the Cape Fold Belt Syntaxis that lies north of the Worcester Fault. Most of the area consists of folded Cape Supergroup (primarily Witteberg Group) rocks. Fold styles of all fold trends are essentially the same. However, different multilayer rheologies led to the development of either sinusoidal or kink-like fold geometries in different parts of the cover sequence. The character of Witteberg sediments led to the development of large megakink folds and peculiar fold zones in this part of the sequence. Fold trends in the Ceres Syntaxis vary between NW-SE, NE-SW and E-W. The southern part of the area is dominated by the NE-SW trend, with the NW-SE trend being only important in the west. Interference between these two trends only exists in the Witteberg Group, where it occurs as crossing linear fold zones and conjugate, intersecting kink folds . Cross-folding relationships in the north-eastern part of the Ceres Syntaxis indicate that the area had been affected by two contemporaneous, orthogonally opposed compressions that worked simultaneously in different parts of the multilayer. Differences in the magnitude of strain, or in the local timing of fold initiation, produced local refolding or transecting relationships. The microfabric of Witteberg sandstones suggests deformation under conditions of low temperature and pressure, as well as low strain rates. Some microfabrics also indicate that substantial buckle shortening occurred while the Middle and Upper Witteberg beds were still unlithified. Isotopic dating of Cedarberg shale from both main trends did not yield unequivocal results, mainly due to the deformatio~al intensity. The positioning of the Cape low Fold Belt Syntaxis was strongly influenced by basement tectonic grain and basin floor relief. The NW and NE fold trends formed on a heterogeneous basement that resolved the stress configuration into components which external . acted simultaneously towards the north-west and north-east. Ecca and Beaufort Group sedimentation patterns in the western Karoo corroborate the above findings. / AFRIKAANSE OPSOMMING: Die Ceres-sintaks beslaan daardie deel van die sintaks van die Kaapse Plooigordel wat noord van die Worcesterverskuiwing Ie. Die gebied bestaan grotendeels uit geplooide gesteentes van die Supergroep Kaap (hoofsaaklik Groep Witteberg). AIle plooirigtings openbaar dieselfde plooistyl. Reologiese verskille in'die rnultilaehet egter gelei tot die ontwikkeling van of sinusoidale ~f knikvorrnigeplooie in verskillende dele van die dekgesteentes. Die Wittebergsedirnente se aard het veroorsaak dat rnegaknikkeen eienaardige plooisones in hierdie deel van die opeenvolging ontstaan het. Plooirigtings in die Ceres-sintaks wissel tussen NW-SO, NO-SW en O-W. Die NO-SW plooirigting oorheers in die suidelike deel van die gebied, terwyl die NW-SO plooirigting eintlik net in. die weste belangrik is. Interferensie van hierdie twee.hoofrigtings korn slegs voor in die Groep Witteberg, waar dit as dwarssnydende lineere plooisones en snydende, konjugerende knikke aanwesig is. Onderlinge verhoudings tussen kruisplooie in die noordoostelike Ceres-sintaks, toon dat die gebied beinvloed is deur twee gelyktydige drukspannings wat reghoekig op rnekaar ingewerk het, sorntyds in effens verskillende dele van die rnultilaag.Verskille in die spanningsbedrag en tydsberekening het lokale herplooiing of dwarssnydende strukture veroorsaak. Die mikrornaaksel van die Wittebergsandsteen toon dat die vervorming onder lae temperatuur- en druktoestande, tesame met 'n lae vervorrningsternpo, plaasgevind het. Die rnaaksel toon ook aan dat heelwat buigplooiing plaasgevind het terwyl die Middel- en Bo-Witteberglae nog ongekonsolideer was. Isotopiese datering van Sederbergskalie afkornstigvan die twee hoofplooirigtings, het weens die lae vervormingsintensiteit swak resultate gelewer. Die posisie van die sintaks van die Kaapse Plooigordel, insluitende die van die Ceres-sintaks, is sterk' belnvioed deur die tektoniese grein en re~i~f van die vloergesteentes. Die heterogene vloer waarop die NW en NO plooie gevorrn het, het daartoe gelei dat die eksterne spanningsopset verdeel is in kornponentewat gelyktydig na die noordweste en noordooste gewerk het. Sedirnentasiepatrone in die Groepe Ecca en Beaufort ondersteun bostaande afleidings.

M.Sc. / The configuration of the supercontinent Rodinia, at the end of the Mesoproterozoic to the beginning of the Neoproterozoic (1100-750 Ma), and its subsequent break up into cratonic fragments that would later result in the formation of Gondwana (Early Palaeozoic), is still not completely understood. This is largely due to ambiguity surrounding relationships between cratons, craton evolution and timing of significant tectonic or sedimentary events. Particular to this study is the evolution and palaeogeographic history of the Kalahari Craton and a comprehensive provenance analysis of Neoproterozoic to early Palaeozoic clastic sedimentary rocks from the Kango Inlier (Saldania Belt, South Africa). This includes the Cango Caves and Kansa Groups as well as the Schoemanspoort and the adjacent Peninsula Formation (Table Mountain Group, Cape Supergroup). A well established lithostratigraphy, in addition to recent establishment of age constraints by UPb zircon dating and microfossil evidence, allowed for strategic sampling with the objective of gaining insight to the crustal evolution of SW Gondwana. In this study, a progression from immature, moderately altered rocks in the Cango Caves Group (Upper Neoproterozoic) to mature, strongly altered rocks in the Lower Palaeozoic Kansa Group and overlying formations is observed. Thus, rapid sedimentation of the former is anticipated, while the subsequent formations developed at a passive/rifted margin culminating in the laterally extensive deposition of the Peninsula Formation. Ongoing extensional movement is evident due to chronologically deeper-water facies and the progressive influence of a less fractionated component in the Cango Caves Group, particularly in the Huis Rivier Formation. The association of these rocks with an active margin is not certain since index trace element concentrations are too high for typical arc terranes. Thus, the mixing of a younger (570-600 Ma) magmatic source (close to an active margin) with mafic and felsic rocks of the older Mesoproterozoic Natal- Namaqua Mobile Belt (NMB) is the most likely possibility. A maximum, pre-Cape Granite age of 571 Ma can be assigned to the Huis Rivier Formation (Cango Caves Group) by detrital zircon dating, and thus correlation with the Malmesbury Group can be made. Ediacaran age zircons might be related to the active continental margin (Trans Antarctic Orogen) surrounding southern Gondwana, but this is still hypothetical. The post-Cape Granite Kansa Group and overlying Schoemanspoort Formation were most likely deposited as basin infill subsequent to folding and transtensional tectonics affecting the underlying Cango Caves Group. The Kansa Group may be comparable with the Klipheuwel Formation (southwest South Africa) in terms of its stratigraphic position beneath the Table Mountain Group. Deposition of the Table Mountain Group is much younger than previously believed in light of Ordovician zircon ages (471, 485, 499 Ma) obtained from the underlying Kansa Group. However, the provenance of these thus far unheard of ages for magmatic events in South Africa is a matter of contention. The proximal Ordovician Ross-Delamerian Orogenic event in Antarctica is the most likely source. Peninsula Formation deposition represents a cover sequence i.e. the culmination of small isolated basins (e.g. the Kansa Group and lower Table Mountain Group) into a larger, laterally extensive basin where reworking played a dominant role. This basin is likely to be a rift-related. However, it is not clear which crustal entity rifted away from vi South Africa and if, during the Ordovician an, active continental margin further to the south - bridging the South American Famatina Orogen with the Ross-Delamerian arc in Antarctica - existed. The Natal-Namaqua Mobile Belt appears to be the predominant source throughout the succession as indicated by Nd-isotope data and zircon populations. This implies that simple crustal recycling of Natal-Namaqua basement (or rocks with similar Nd-isotope characteristics) led to the genesis of the magmatic material younger than 1 Ga, observed in this study.

A thesis submitted to the Faculty of Architecture, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy Johannesburg, 1996 / This thesis is set within the historical context of the commercial empire of the VOC (Dutch East India Company), which established a refreshment post for its ships at the Cape of Good Hope, South Africa, in 1652. The central proposition of the thesis is that the architectural principles established at the Cape between 1652 and 1710 had a greater influence on subsequent developments than has previously been acknowledged. This proposition challenges the widely accepted theory that Cape Dutch architecture developed as an evolution from vernacular beginnings. Re.search in the field to date has focused largely on Cape Dutch buildings, dating from after the mid-18th century, and on later survivals of vernacular types. As a result the buildings erected prior to 1710, defined here as proto-Cape Dutch, have been largely ignored. To redress this imbalance, the thesis investigates the proto-Cape Dutch period in its own right, by presenting the widest possible range of building types erected during this period. Since few of these buildings survive, the evidence for the thesis was derived largely from archival material. This comprised three types of contemporary sources: the official records of the VOC, the written accounts of visitors to the Cape, and the drawings of visiting artists. Some sources were clearly unreliable, but in several cases it was possible to reconcile evidence which initially appeared to be contradictory. The interpretation and evaluation of this research is addressed in Part 1 of the thesis. The architectural evidence is presented in Part 2, where the process of analysis and reconciliation is revealed. This process facilitated the detailed reconstruction of some of the more prominent buildings of the proto-Cape Dutch period no longer in existence. The thesis contends that such buildings, with sophisticated plans and Renaissance proportions, were the stimulus for the development of Cape Dutch architecture later in the 18th century. The thesis thus comprises three major components: the development of a research method; the re-evaluation through this method of a number of buildings known primarily from documentary sources; and the proposition based on this re-evaluation that Cape Dutch architecture was a simplification of the precedent established by the more sophisticated buildings of the proto-Cape Dutch period. The method employed and the conclusions drawn from the evidence may suggest applications in similar colonial circumstances elsewhere.

Magister Artium - MA (History) / In the following two chapters I will attempt to offer a more systemic account of St. Helena immigration to South African between 1838 and 1948. To date, no such study has been undertaken, despite a vibrant oral tradition amongst the descendants of St. Helena immigrants celebrating their St. Helenian heritage and often, in peculiar fashion, romanticise their Island of provenance. The commencement date for my chosen timeframe emerges from a need to authenticate rather tenuous historical accounts of St. Helena’s first mass emigration for the Cape of Good Hope in 1838. Where cases of migration are discussed, these are either incidences of large-­scale 41, often aided, migration and settlement, or of those St. Helena migrant workers initially employed under temporary contacts to work in South Africa, specifically within burgeoning industrial sectors of the late-­nineteenth or early-­twentieth century South Africa.

Thesis (MA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: This study deals with the build-up to, and resultant reactions against, regulating sexual practices in the Cape Colony, especially the Contagious Diseases Acts in 1868 and 1885. The focus will be on the existence of venereal disease as a colonial epidemic. The wider context in terms of Britain, India, Hong Kong, Singapore and Australia will also be taken into account. The research is based on a theoretical framework made up of three components; gender, power and moral politics. The role of gender will be looked at through the existence of the double standard and the prostitute. Power and the existing relations between the colonies and the colonisers will be looked at by addressing the issue of race, superiority and the exportation of the colonial mindset. Moral politics will be analysed through the discussion of purity campaigns, women’s role in society and the medical aspect of politics. Within this thematic framework, the focus of the study will then move to the Cape Colony and the existence of regularity practices there. This study seeks to establish the ways in which regulation developed at the Cape and in doing so hopes to contribute to the existing historiography. / AFRIKAANSE OPSOMMING: Hierdie studie fokus op die aanloop tot en die daaropvolgende reaksies ten opsigte van regulatoriese sekspraktyke, waarvan die bekendste die Aansteeklike Siektes Wette van 1869 en 1885 was. Daar word na die bestaan van veneriese siekte as ‘n koloniale epidemie gekyk. Die breër konteks van Brittanje, Indië, Hong Kong, Singapoer en Australië word ook in ag geneem. Die navorsing is gebaseer op ‘n teoretiese raamwerk van drie komponente: geslagtelikheid (“gender”) , mag en morele politiek. Die rol van geslagtelikheid word betrag na gelang die bestaan van dubbele standaarde en die prostituut. Mag en die bestaande verhoudinge tussen die koloniseerders en die wat gekoloniseer, word aangespreek deur te let op die kwessie van ras, meerderwaardigheid en die toepassing van ‘n koloniale denkpatroon. Morele politiek word ontleed deur te let op die bespreking van kuisheid kampanjes, vroue se rol in die samelewing en die mediese aspekte van politiek. Binne hierdie teoretiese raamwerk word die bestaan van regulatoriese praktyke in die Kaapkolonie bespreek. Die studie poog om vas te stel op welke wyses regulatoriese praktyke in die Kaapkolonie ontwikkel het en sodoende word gepoog om ‘n bydrae tot die bestaande historiografie te maak.

M.A. / The study of South African history has developed considerably over the last number of years to incorporate new ideas, approaches, and styles. However, the standard works on South African historiography continue to provide a reader with very little beyond a descriptive framework to allow historians to locate their work within the body of South African historical knowledge. This dissertation attempts to address this shortcoming by encouraging and advocating a more analytical approach to the field of historiography. Here, the approach taken is the same as that taken by Hayden White in writing his work Metahistory: The Historical Imagination in Nineteenth-Century Europe. At the same time, a stronger focus is placed on the role of historical context. To demonstrate the advantages of this type of analysis, of analytical historiography over the traditional conception of historiography, I have chosen the example of South African slavery under Dutch administration, 1652 – 1795. The question that this work then attempts to answer is: How can our understanding of South African Slave Historiography be enlightened by the use of Analytical Historiography? The work is divided into two, with the first section dealing with the theoretical and methodological requirements of the work. The second deals with the Whiteian analysis of a number of works on slavery at the Cape before 1795.1 This is followed by the final analysis and conclusion.

As the title indicates, this is a study of the historical emergence of geography as a subject in Cape schools, and covers the period 1772-1951. The account is not merely descriptive and factual, for wherever possible an attempt is made to assess the nature and scope of the geography which was taught at different periods in relation to modern, authoritative ideas concerning the pedagogic application of the subject in the school. The work as a whole is predominantly concerned with the historical development of geography in the secondary school. However, in the initial four chapters the slight and insubstantial nature of the available data precludes the possibility of differentiating between geoeraphy of primary standard and that of secondary standard, and in these early chapters all references to the subject are consequently generalized. In Chapter 5, which deals with the period during which Langham Dale was Superintendent-Genera l of Education, geography of secondary standard becomes distinguishable from that of primary standard for the first time, and from this point onwards the two are differentiated to the fullest extent possible, and the former is chiefly emphasized. The entire study is presented against a broad background of relevant, educational developments of a general nature.
