A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy Johannesburg, August 2015 School of Geosciences, University of the Witwatersrand / The possibility of extensive shale gas resources in the main Karoo Basin has resulted in a renewed focus on the basin, and particularly the Whitehill Formation. The main Karoo Basin has been the subject of geological studies since before the 1920s, but geophysical data provides an opportunity to shed new light on the basin architecture and formation. In this thesis, I use regional gravity, magnetic and borehole data over the basin, as well as vintage seismic data in the southern part of the basin. Modern computational capacity allows for more information to be extracted from these seismic data, and for these data to be better integrated with potential field data. The integration of datasets in a three-dimensional model (3D) has allowed for a better understanding of the shape of the basin and its internal structure, in turn shedding light on basin formation. A new depth map of the basin constructed using this extensive database confirms that the basin deepens from on- to off-craton. The basin is deepest along the northern boundary of the Cape Fold Belt (CFB), with a depth of ~4000 m in the southwestern Karoo and ~5000 m in the southeastern part of the basin. Sediment thickness ranges from ~5500 to 6000 m. The Whitehill Formation along this boundary reaches a depth of ~ 3000 m in the southwest and ~4000 m in the southeast. Despite limited boreholes in this region, the basin appears to broadly deepen to the southeast. These seismic and borehole data also allow for mapping of the Cape Supergroup pinch-out below the Karoo basin (32.6°S for the Bokkeveld and 32.4°S for the Table Mountain Group), with the basin reaching a thickness of around 4 km just north of the CFB. The gravity effect of these sediments in the south is not sufficient to account for the low of the Cape Isostatic Anomaly near Willowmore and Steytlerville. This ~45 mGal Bouguer gravity low dominates the central region of the southern Karoo at the northern border of the CFB. The seismic data for the first time show uplift of lower-density shales of the Ecca Group (1800 – 2650 kg/m3) in this region, and structural and seismic data suggest that these lower density sediments continue to depth of 11 to 12 km along normal and thrust faults in this region. Two-dimensional density models show that these shallow crustal features, as well as deeper lower crust compared to surrounding regions, account for the anomaly. These seismic and borehole data also allow for constraints to be placed on the distribution and geometry of the dolerite intrusions that intruded the basin after its formation, and in some cases impacted on the shale layer, to be constrained. The highest concentrations of dolerites are found in the northwest and east of the basin, pointing towards two magma sources. The region of lowest concentration is in the south-central part of the basin. Here the intrusions are confined to the Beaufort Group, ~1000 m shallower than the shale reservoir, suggesting it should be the focus of exploration efforts. These dolerite sills are shown to be between 5 and 30 km wide and are saucer-shaped with ~ 800 m vertical extent, and dips of between 2° and 8° on the edges. The sheets in the south of the basin extend for over 150 km, dipping at between 3° and 13°, and are imaged down to ~ 5 km. This change in dip of the sheets is linked to deformation within the Cape Fold Belt, with greater dips closer to the belt, although these sheets do not appear to intrude strata dipping at more than 15 to 20°. In order to understand the shape of the Karoo basin and construct a 3D model of the basin, an understanding is needed of the underlying basement rocks. The Beattie Magnetic Anomaly (BMA) that stretches across the entire southern part of the basin forms part of the basement Namaqua-Natal Belt. Filtered magnetic data confirm that the Namaqua and Natal Belts are two separate regions with different magnetic characteristics, which is taken into account during modelling. The BMA is shown to be part of a group of linear magnetic anomalies making up the Natal Belt. The anomaly itself will therefore not have an individual effect on basin formation, and the effect of the Natal Belt as a whole will have to be investigated. An in-depth study of outcrops associated with one of these linear magnetic anomalies on the east coast of South Africa suggest the BMA can be attributed to regions of highly magnetic (10 to 100 x 10-3 SI) supracrustal rocks in Proterozoic shear zones. Along two-dimensional magnetic models in the southwestern Karoo constrained by seismic data, these magnetic zones are modelled as dipping slabs with horizontal extents of ~20-60 km and vertical extents of ~10-15 km. Body densities range from 2800- 2940 kg/m3 and magnetic susceptibilities from 10 to 100 x 10-3 SI. These, as well as other geophysical and geological constraints, are used to construct a 3D model of the basin down to 300 km. Relatively well-constrained crustal structure allows for inversion modelling of lithospheric mantle densities using GOCE satellite gravity data, with results in-line with xenolith data. These results confirm the existence of lower density mantle below the craton (~3270 kg/m3) that could contribute to the buoyancy of the craton, and an almost 50 kg/m3 density increase in the lithospheric mantle below the surrounding Proterozoic belts. It is this change in lithospheric density along with changes in Moho depths that isostatically compensate a large portion of South Africa’s high topography (<1200 m). The topography higher than 1200 m along the edge of the plateau, along the Great Escarpment, are shown to be accommodated by an asthenospheric buoyancy anomaly with a density contrast of around 40 kg/m3, while still mimicking the Bouguer gravity field. These findings are in line with recent tomographic studies below Africa suggesting an “African Superplume” or “Large Low Velocity Seismic Province” in the deep mantle. The basin sediment thickness maps were further used to investigate the formation of the main Karoo Basin. This was accomplished by studying the past flexure of the Whitehill Formation using north-south two-dimensional (2D) profiles. Deepening of the formation from ~3000 m in the southwest to ~4000 m in the southeast is explained using the concept of isostasy, i.e., an infinite elastic beam that is subjected to an increasing load size across the Cape Fold Belt. Load height values increase from 4 km in the southwest to 8 km in the southeast. This larger load is attributed here to “locking” along a subduction zone further to the south. The effective elastic thickness (Te) of the beam also increases from around 50 km over the Namaqua and Natal Belts in the southwest to 80 km over the Kaapvaal Craton and Natal Belt in the southeast. The changes in Te values do not correlate with changes in terrane, i.e., a north to south change, as previously though. The large extent and shape of the Karoo basin can therefore, in general, be explained as a flexural basin, with the strength of the basement increasing towards the southeast. Therefore, while factors such as mantle flow could have contributed towards basin formation, reducing the load size needed, it is no longer necessary in order to account for the large extent of the basin. This flexure model breaks down further to the southeast, most likely due to a very high Te value. This could be the reason for later plate break in this region during Gondwana breakup. It is inferred that this increase in Te is linked to the buoyancy anomaly in the asthenospheric mantle.

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the Degree of Master of Science. Johannesburg, 2016. / Pareiasaurs were abundant, large, herbivorous parareptiles of the middle and late Permian which had a global distribution. The most basal pareiasaurs are found only in the middle Permian of South Africa, suggesting a Gondwanan origin for the group. Despite their relative abundance, most pareiasaurs are poorly known, especially the large middle Permian South African taxa that went extinct at the end of the Tapinocephalus Assemblage Zone. Historic taxonomic confusion was reduced with studies by Lee (1995, 1997a) that addressed the alpha-taxonomy of all pareiasaurs. He reduced the middle Permian South African pareiasaurs from 11 to four species: Bradysaurus baini, B. seeleyi, Embrithosaurus schwarzi and Nochelesaurus alexanderi. However this revision did not include detailed anatomical descriptions of any of the middle Permian South African Tapinocephalus Assemblage Zone taxa. The first detailed cranial description of Embrithosaurus schwarzi is presented in this contribution. Within the middle Permian pareiasaurians, Embrithosaurus has unique wide, short and stubby teeth with nine marginal cusps arranged more regularly. A cranial taxonomic reassessment of all middle Permian pareiasaurs has confirmed the validity of the four taxa identified by Lee and produced updated cranial diagnoses for each species. Diagnostic features noted by Lee and retained include an autapomorphic large distinctive maxillary boss on a strongly buckled or bent maxilla for B. baini, distinctive horizontally flat and pointed bosses on the posterior margin of the quadratojugal for Nochelesaurus and the smallest cheek flanges for B. seeleyi. Using the updated diagnoses, re-identification of 39 specimens out of 108 studied has produced updated biostratigraphic ranges for the middle Permian species. B. seeleyi is the first to make an appearance, in the middle Koornplaats Member of the Abrahamskraal Formation. B. baini first appears in the upper iii Koornplaats Member, Nochelesaurus in the Swaerskraal Member, and Embrithosaurus in the lower Moordenaars Member of the Abrahamskraal Formation. All taxa disappear by the top of the Karelskraal Member of the Abrahamskraal Formation, confirming that all the middle Permian pareiasaur species went extinct at the end of the Tapinocephalus Assemblage Zone. / MT2017

The Gemsbok Sub-basin is situated in the south-western corner of the Kalahari Karoo Basin and extends south from the Kgalagadi District of Botswana into the Northern Cape (South Africa); and west into the Aranos Basin (southeast Namibia). The Sub-basin preserves a heterogeneous succession of Upper Palaeozoic to Lower Mesozoic sedimentary and volcanic rocks of the Karoo Supergroup. Because the succession is largely covered by the Cenozoic Kalahari Group, the stratigraphy of the succession is not as well understood as the Main Karoo Basin in South Africa. Most research in the Gemsbok Sub-basin is based on borehole data. This study focuses on the intrabasinal correlation, depositional environments and provenance of the Karoo Supergroup in the Gemsbok Sub-basin in Botswana and Namibia. Based on detailed sedimentological analyses of 11 borehole cores of the Karoo Supergroup in the Gemsbok Sub-basin of Botswana and Namibia, 8 facies associations (FAs) comprising 14 lithofacies and 2 trace fossil assemblages (Cruziana and Skolithos ichnofacies) were identified. The facies associations (FA1 to FA8) correspond to the lithostratigraphic subdivisions (the Dwyka Group, Ecca Group, Beaufort equivalent Group, Lebung Group [Mosolotsane and Ntane formations] and Neu Loore Formation) of the Karoo Supergroup. Sedimentological characteristics of the identified facies associations indicate the following depositional environments: glaciomarine or glaciolacustrine (FA1, Dwyka Group), deep-water (lake or sea) (FA2, Ecca Group), prodelta (FA3, Ecca Group), delta front (FA4, Ecca Group), delta plain (FA5, Ecca Group), floodplain (probably shallow lakes) (FA6, Beaufort Group equivalent), fluvial (FA7, Mosolotsane and Neu Loore formations) and aeolian (FA8, Ntane Sandstone Formation). The Dwyka Group (FA1) forms the base of the Karoo Supergroup in the Gemsbok Subbasin and overlain by the Ecca Group deposits. Three types of deltas exist within the Ecca Group: fluvial-dominated; fluvial-wave interaction and wave-dominated deltas. The Gemsbok Sub-basin was characterised by rapid uplift and subsidence and high sediment influx during the deposition of the Ecca Group. Petrographic and geochemical analyses of the Ecca Group sandstones revealed immature arkose and subarkose type sandstones dominated by angular to subangular detrital grains, sourced from transitional continental and basement uplifted source areas. The sandstones of Ntane Sandstone Formation are classified as subarkoses and sourced from the craton interior provenances.

Vegetation monitoring, recording the recovery or change in plant cover over time, for several Karoo shrubs was undertaken to evaluate the Savory Grazing System on a farm in the Succulent Karoo. This evaluation was quantified by establishing if the proposed 120- day rest period between grazing events was sufficiently long enough for complete recovery of the vegetation. Complete recovery was described as sufficient regrowth after a grazing event so that continual cover loss would not result over time. Optimum resting periods would ensure that cover loss, due to grazing, could be recovered so that plant size and reproductive potential was not detrimentally affected. The ellipse intercept method was used to sample piospheres (or zones of attenuating animal impact) around water points in two vegetation types. From these results, 320 line transects for vegetation monitoring were located between 140 and 180m from the water points. One and a half year old piospheres of one farm were compared to seventeen year old piospheres on another farm with similar vegetation composition. The piospheres on the younger farm were expanding at an approximate linear rate of 80m per year, however, this rate slows considerably, as was found on the farm with older piospheres. Stability or equilibrium appears to be reached at approximately 320m from the water point in the older system. The line transects were used to record the change in cover of palatable and unpalatable Karoo shrubs on a monthly basis over an 18 month period. In all instances it was concluded that the proposed 120-day rest period was not sufficiently long enough for complete recovery of the vegetation. The highly palatable species, especially Osteospermum sinuatum and Tetragonia spp., were the most heavily utilized and detrimentally affected. Larger individuals of the palatable shrubs O. sinuatum and Tetragonia spp. were more severely grazed than smaller individuals as a result of smaller individuals utilising spiny nurse plants under which to establish. If the present rest period is continued the result could be overgrazing and local extinction of these important fodder species. The responses of two highly palatable species, O. sinuatum and Tetragonia spp., were monitored closely in relation to rainfall and grazing events. Grazed and ungrazed (protected) individuals were monitored over one year to substantiate the results obtained from the line transects. The rest period was again found to be too short for full recovery and was also found to be reducing the reproductive output of O. sinuatum and Tetragonia spp.. The recruitment of O. sinuatum and Tetragonia spp. was also measured by comparing seedling establishment in grazed, ungrazed (vegetation protected from sheep grazing) and cleared vegetation. In an attempt to rehabilitate these rangelands, Pteronia pallens, a dominant unpalatable shrub, was cleared and the resultant seedling recruitment of O. sinuatum and Tetragonia spp. monitored and compared to grazed and ungrazed vegetation. Juvenile recruitment of these species was found to be significantly lower in the grazed than in the ungrazed vegetation. Recruitment of Tetragonia spp. was found to be significantly higher in the cleared strip compared to the grazed and ungrazed vegetation. The results obtained in this study suggest that the present grazing regime is having a detrimental effect on the vegetation and that revised management procedures are needed to ensure the conservation of these rangelands. The rest periods between grazing events need to be lengthened as well as a reduction in stock numbers. Certain camps need to be skipped on a seasonal basis during the flowering season in order to increase the reproductive output of highly palatable species. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 1995.

The New Amalfi Sheet is a highly differentiated tholeiitic intrusion which is situated between the towns of Matatiele and Swartberg in East Griqualand. It lies within the Central area of the Karoo Igneous Province. Rock types range from dolerites at the base and top through to a highly differentiated granophyre which is found as a 'sandwich horizon' within the top half of the sheet. The most evolved granophyre represents 15.86% of the initial liquid, which was found to be very similar in composition to the average Lesotho-type magma of Marsh and Eales (1984). The paragenetic sequence was found to be chromite → olivine → plagioclase → pigeonite and augite. Cumulus magnetite and ilmenite enter the paragenetic sequence together with immiscible sulphide droplets after 35% crystallization. In the late stages of crystallization, augite changes composition towards ferrohedenbergite. The reappearance of iron-rich olivine coincides with the disappearance of pigeonite and apatite appears as a cumulus phase for the first time after 70% crystallization. Granophyric intergrowth, which contains coarse perthitic Kfeldspar, becomes the most abundant modal entity within the most evolved granophyres. Differentiation was dominated by fractionation of plagioclase and pyroxene, with subordinate olivine and opaque-oxide fractionation. A minor amount of assimilation of country rock occurred within the topmost granophyres. The intrusion has been dated, using the Rb-Sr isochron method, at 178.37 ± 5.52 Ma. Extensive subsolidus deuteric alteration has resulted in the formation of a complete series of hydrothermally altered clinopyroxenes which are enriched in CaO but depleted in TiO₂ compared to the unaltered magmatic clinopyroxenes. It has also resulted in the formation of abundant vermiform ilmenite in the most evolved rocks, recognized by the fact that this phase is enriched in MnO compared to magmatic ilmenites. The very iron-rich orthopyroxene, ferrohypersthene, was found to have crystallized, during cooling of the sheet from the intercumulus liquid. Olivine in the dolerite re-equilibrated with the intercumulus liquid, becoming more iron-rich in composition.

In this research the conflict between economic and conservation imperatives in the proposed exploration of shale gas in the South Western Karoo Basin was investigated. The primary aim of this study was to come to a theoretical understanding of the situation through a critical analysis of existing documents which allowed me to outline in detail the two opposing perspectives that either promote or resist a shale gas exploration project. The second objective of this research was to present empirical data from both a questionnaire completed by 20 respondents and two interviews, that helps amplify and verify arguments for or against a shale gas exploration project. The theoretical and empirical components of the research offer the basis for a balanced assessment of the viability of shell gas exploration in the Karoo. Using three fundamental assessment criteria (social, economic and environmental) for what constitutes a sustainable development project the gathered data was analysed in order to help ascertain whether or not the shale gas exploration project is a worthwhile development project. The question answered was whether a shale gas exploration project meets its social, economic and environmental mandates. From this, the final objective of this research was to make recommendations concerning what a responsible policy would be concerning land use in the Karoo.

‘Karoo lamb’ is a product with specific regional qualities that are based on, among other factors, the natural environment present in the region of origin. Together with the specific product qualities, regional image factors create a unique identity for a product, as is the case of ‘Karoo lamb’, in this way bringing about added value. Consumers will only consume food products that fulfil their specific requirements and have become more demanding about what they want. As food markets have become more globalised, consumers have become more concerned about the origin of the food they eat, with decreased confidence in the quality and safety of foods produced outside their local region or country. Traceability systems address these concerns, and the importance of establishing a link between a product, producer and place of production has therefore gained momentum as a trend. The overall goal of the research was to explore the role and contribution of traceability as a system relating to a product of origin, specifically ‘Karoo lamb’, and the influence it has on consumers’ decision-making processes when selecting and purchasing ‘Karoo lamb’. Consumer decision making is a complex and dynamic process that can be explained according to a consumer decision model that specifies its various stages. The research was conducted in three phases. During the first phase a quantitative research approach was followed to investigate and describe the audit processes that have been implemented by different retailers in South Africa regarding the traceability of lamb meat. In the second phase, focus group sessions, a recognised qualitative research technique, were conducted to identify the product attributes that were critical to consumers’ preferences and choices regarding the product, ‘Karoo lamb’. In the third phase the attributes, namely price, safety, quality, traceability and origin, were identified as significant factors influencing consumer choice and used in a conjoint questionnaire. A quantitative approach was followed in phase three and a questionnaire was used to measure the importance individual consumers attach to the different levels of the various product attributes. The utility values were based on the survey participants’ evaluation of the complete product. Price is often known to be one of the most important and determining factors in the consumer’s decision-making process. A higher price can sometimes symbolise better quality or safety of the product for the consumers. The results from the conjoint questionnaire have shown that price, as an extrinsic attribute, was found to be the most important factor in a consumer’s decision-making process at 30.4% when purchasing lamb. Safety at 23.1% was the second most important attribute after price. This is not surprising given the legacy of BSE and e-coli outbreaks that were given much publicity in the press. The third attribute affecting the purchasing decision was quality at 17.0%. The fourth attribute of traceability affected the purchasing decision at 15.7% and the importance of the fifth attribute, region of origin, was 13.8%. According to the participants, the origin attribute had the lowest rating of importance of all five attributes selected for the conjoint questionnaire. As the conjoint experiment was conducted electronically, the participants of the conjoint questionnaire were solicited with the assistance of a marketing research firm, Consulta Research (Pty) Ltd., based in Centurion in the Gauteng province of South Africa, and were part of the consumer panel of consenting survey participants for the company. In total 352 completed questionnaires were used in the data analysis. The buying and/or consuming of mutton or lamb were the only criteria that needed to be met for participation in the conjoint questionnaire. In conclusion it can be said that there is a lack of certification and guarantee in South Africa that the product that is marketed as ‘Karoo lamb’ truly originates from the Karoo, and consumers can easily be misled as to the true origin of the lamb being sold. Traceability can be an important tool to help to establish the authenticity of food products and to check that claims made by producers are true. AFRIKAANS : Karoo lamsvleis is ‘n streeksgebonde produk wat gebaseer is op die natuurlike omgewing in die gebied van oorsprong. Tesame met die spesifieke produk gebaseerde kwaliteite word ‘n unieke produk identiteit geskep deur die streeks faktore soos gesien met Karoo lam en hiermee bring dit toegevoegde waarde mee. Verbruikers sal slegs voedselprodukte aankoop en eet wat hul spesieke aanvraag benodigdhede vervul. Omdat voedselmarkte wêreldwyd meer en meer impak maak op verbruikers begin hulle konsentreer op die herkoms van produkte. Verbruikers het verminderde vertroue in die kwaliteit en veiligheid van produkte wat geproduseer word buite streeks- en landsgrense. Naspoorbaarheid sisteme spreek hierdie probleme aan en die belangrikheid om ‘n skakel tussen produk, produsent en plek van produksie te vind het veld gewen as tendens. Die primêre doel van hierdie navorsingsstudie was om die rol en bydrae van naspoorbaarheid as ‘n sisteem ten opsigte van produk oorsprong en spesifiek Karoo lamsvleis te ondersoek, asook die invloed daarvan op verbruiker besluitnemings tydens die keuse en aankoop van Karoo lamsvleis. Omrede die verbruikers besluitnemingsproses kompleks en dinamies is kan dit verduidelik word met ‘n verbruikers besluitnemings model wat die verskillende fases van die proses beskryf. Die studieprojek is uitgevoer in drie fases. Met die eerste fase is ‘n kwantitatiewe benadering gevolg om ondersoek in te stel en te beskryf hoe en watter ouditprosesse geïmplimenteer is deur groothandelaars ten opsigte van die naspeurbaarheid van lamsvleis in Suid Afrika. Tydens fase twee is fokus groep besprekings, ‘n kwalitatiewe navorsings tegniek, geloods om die produk kenmerke wat verbruikers besluitneming ten opsigte van die produk lamsvleis beïnvloed te bepaal. Die kenmerke prys, veiligheid, kwaliteit, naspeurbaarheid en oorsprong is geïdentifiseer en gebruik in fase drie, die voorkeurkeuse ontleding. ‘n Kwantitatiewe benadering is gevolg in fase drie om die belangrikheid te bepaal wat verbruikers heg aan die verskillende kenmerke en die vlakke van die onderskeie produk kenmerke. Prys is bekend as een van die mees belangrikste en invloedryke faktore in die verbruikers besluitnemings proses. ‘n Hoër prys simboliseer soms beter kwaliteit en veiligheid aan ‘n verbruiker. Die resultate van die voorkeurkeuse ontleding het getoon dat prys met 30.4% as ‘n uiterlike kenmerk, die belangrikste invloed het op verbruikers besluitneming. Veiligheid met 23.1% was die tweede belangrikste kenmerk na prys. Bogenoemde was nie ‘n verrassing nie aangesien die pers wêreldwyd al baie aandag gegee het aan die uitbreking van die e-coli epidemies. Kwaliteit was die derde belangrikste kenmerk wat verbruikers besluitneming bëinvloed het met 17.0%. Naspeurbaarheid as kenmerk het die besluitnemings proses bëinvloed met 15.7% en oorsprong in die vyfde plek met 13.8%. Daar is gevind dat oorsprong as kenmerk verbruikers se besluitneming die minste beïnvloed het. Die deelnemers aan die elektroniese voorkeurkeuse ontledingsopname is verkry vanaf die databasis van die bemarking navorsings maatskappy Consulta Research (Pty) Ltd, wat geleë is in Centurion, in die Gauteng provinsie van Suid Afrika. ‘n Totaal van 352 voltooide vraelyste is gebruik vir die data analise. Die aankoop en verbruik van lam en skaap vleis was die enigste kriterium wat gebruik is in die werwingsproses van die deelnemers. Samevattend kan genoem word dat daar ‘n gebrek bestaan in Suid Afrika in die sertifisering en waarborg van die produk Karoo lamsvleis wat bemark word as afkomstig van die Karoo. Sodoende kan verbruikers maklik mislei word oor die ware oorsprong van die produk. Naspeurbaarheid kan ‘n baie belangrike instrument wees om die geloofwaardigheid van voedsel te bepaal en te verseker dat die aannames ten opsigte van oorsprong wat produsente maak die waarheid weerspieël.
