Characterisation of natural radioactivity in Karoo Basin groundwater prior to shale gas exploration
… of unconventional shale-gas development in the Karoo Basin (South Africa) has created the need to obtain baseline data on natural radioactivity in Karoo groundwaters. The Karoo Basin groundwater radiological baseline developed through this study could serve as a reference to research potential …

The sedimentary petrology of carbonate nodules in the Elliot Formation, Karoo Supergroup, main Karoo Basin (South Africa)
… part of the Elliot Formation (Stormberg Group, Karoo Supergroup) are often associated with genetically poorly-constrained carbonate nodules. The origin of carbonate nodules i.e., pedogenic versus diagenetic, is important as pedogenic carbonate nodules can be used as palaeoclimate indicators, …

Fluvial facies architecture and provenance history of the Abrahamskraal-Teekloof formation transition (lower Beaufort group) in the main Karoo Basin
… lower Beaufort Group in the southern main Karoo Basin comprises of the fluvio-lacustrine Abrahamskraal and the overlying Teekloof and correlative Middleton Formations. These units are mainly made up of mudrocks with subordinate fine-grained sandstone-rich intervals. The objective of this …

Ichnology and sedimentology of large tetrapod burrows in the latest Early Triassic Katberg Formation, south-eastern main Karoo Basin, South Africa
… the south-eastern and central parts of the main Karoo Basin, Eastern Cape, South Africa. The most interesting site, Hobbs Hill, northwest of Cathcart (Eastern Cape) has numerous burrows, contains an exceptionally well exposed sedimentary succession and bone beds. This site is also the type …

Comprehensive description of a skeleton of Endothiodon Bathystoma (Anomodontia, Therapsida), a dicynodont from the Late Permian of the Karoo Basin of South Africa
… well known from the late Permian deposits of the Karoo Basin of South Africa. It is characterized by rows of internal teeth on the premaxilla and dentary arranged in replacement waves called Zahnreihen; longitudinal ridges running from the premaxilla to the pineal crest; and a prominent pineal …

Life after extinction: palaeoenvironments of the earliest Triassic lower Katberg formation, including the origin of Lystrosaurus Bonebeds from the Karoo Basin, South Africa
… as cold or drought, in the earliest Triassic Karoo Basin.

Position of the Triassic-Jurassic boundary in South Africa and Lesotho : a multidisciplinary approach aimed at improving the chronostratigraphy and biostratigraphy of the Elliot Formation, Stormberg Group
The continental red bed succession of the main Karoo Basin in South Africa and Lesotho, the Elliot Formation (Stormberg Group, Karoo Supergroup), is a significant stratigraphic unit for the regional and global understanding of the Late Triassic - Early Jurassic evolution of terrestrial vertebrate …

Diagenetic, thermal and provenance histories of the Permian lower Ecca Group based on two newly drilled boreholes in the western and eastern main Karoo Basin, South Africa
… the Lower Permian lower Ecca Group in the Main Karoo Basin (MKB) in southern Africa have been identified to form a possible unconventional hydrocarbon reservoir, the gas potential of which is still relatively unknown. The lower Ecca Group is comprised of flysch-like successions of the Prince …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
In north-western Namibia the fills of the Karoo-Etendeka depositories can be subdivided into (1) a Carboniferous-Permian, (2) a Triassic-Jurassic and (3) a Cretaceous megasequence, each recording extensional periods related to successive rifting phases in the evolving South Atlantic. The tectonic …

Cold case files : palaeoforensic and taphonomic study of the Mamafura dicynodont from the end permian
… more abundant than in the rock strata of the Karoo basin in South Afiica. Taphonomy, the transition from biosphere to lithosphere, is of great geological and biological significance and has provided remarkable insight into palaeoenvironments. A partially articulated dicynodont that has been …

An analysis of the potential socio-economic impacts of shale gas development in South Africa
… shale gas exploration applications in the Karoo basin. There are conflicting views on whether the development of the resource will be to the detriment or benefit of the South African economy. This paper makes use of a dynamic Computable General Equilibrium (CGE) model adapted for the South …

Fluvial facies, vertebrate taphonomy and palaeosols of the Teekloof formation (Permian) near Beaufort West, Cape Province, South Africa
The main Karoo Basin of South Africa contains a relatively continuous sequence of continental deposits that accumulated over a 100 million year period from Permo-Carboniferous (280 Ma) to early Jurassic (180 Ma). In the southwestern region of the basin the Karoo succession is approximately 4 000 m …

From grains to tracks: high-resolution sedimentology of track-bearing Stormberg strata, southern Africa
… morphology. In the upper Stormberg Group, main Karoo Basin of southern Africa, diverse trace fossils, primarily comprising Upper Triassic– Lower Jurassic dinosaur tracks, are preserved. Extensive studies have been carried out to document these individual tracksites and to examine the variations …

Spatial and temporal variations in the geometry and composition of the Permian Whitehill Formation South Africa
… important hydrocarbon resource unit in the main Karoo Basin where it occurs in outcrops and up to 4 400 m in the subsurface and thus it is distributed over an area in excess of 260 000 km² in the southern half of South Africa. Although the formation is composed predominantly of black laminated …

Multi-proxy palaeoclimate reconstruction of the permian-triassic mass extinction event
… and Madagascar, and from marine carbonate in the Karoo Basin. However, these sections are all from southern palaeolatitudes. Analysis from the Permian-Triassic terrestrial sedimentary record of the South Urals, in Russia, comprising of many Aridisol and Vertisol horizons has revealed that, like …

Analytical and statistical approaches toward understanding sedimentation in siliciclastic depositional systems
… Permian Skoorsteenberg Fonnation in the Tanqua-Karoo Basin, South Africa. Exceptional exposure permitted a number of lateral correlation studies over a range of scales. The cumulative distribution model is supported by the turbidite distributions broadly subdivided into fan and interfan …

Evaluation of tridactyl theropod tracks in southern Africa: quantitative morphometric analysis across the Triassic–Jurassic boundary
… formations (upper Stormberg Group) of main Karoo Basin, host a diverse tetrapod osteological and ichnite record. Due to an absence of high resolution radioisotopic age determinations, the exact stratigraphic placement of the TJB remains unknown. Although diverse ichnofossils attributed to …
