South Africa's Coalfields – a 2014 Perspective
South Africa's coalfields – a 2014 perspective 1Hancox, P. John and 2,3Götz, Annette E. 1University of the Witwatersrand, School of Geosciences, Private Bag 3, 2050 Wits, South Africa; [email protected] 2University of Pretoria, Department of Geology, Private Bag X20, Hatfield, 0028 Pretoria, South Africa; [email protected] 3Kazan Federal University, 18 Kremlyovskaya St., Kazan 420008, Republic of Tatarstan, Russian Federation Highlights • South Africa’s Coalfields are presented. • The role of Gondwanan coals as palaeoclimate archives is stated. • Future research fields include palynology, sequence stratigraphy, basin fill. Abstract For well over a century and a half coal has played a vital role in South Africa’s economy and currently bituminous coal is the primary energy source for domestic electricity generation, as well as being the feedstock for the production of a substantial percentage of the country’s liquid fuels. It furthermore provides a considerable source of foreign revenue from exports. Based on geographic considerations, and variations in the sedimentation, origin, formation, distribution and quality of the coals, 19 coalfields are generally recognised in South Africa. This paper provides an updated review of their exploration and exploitation histories, general geology, and coal seam nomenclature and coal qualities. Within the various coalfields autocyclic variability is the norm rather than the exception, whereas allocyclic variability is much less so, and allows for the correlation of genetically related sequences. During the mid-Jurassic break up of Gondwana most of the coals bearing successions were intruded by dolerite. These intrusions are important as they may cause devolatilisation and burning of the coal, create structural disturbances and related seam correlation problems, and difficulties in mining operations. -
Response to Letter of 24 April 2019
Exemption Letter – Baberton Mines, Sheba East Prospecting Right Application Heidi Fourie – Palaeontologist Farm: Sheba Siding 939-JU in Ehlanzeni District Municipality, Mbombela Local Municipality, Mpumalanga Province. DMR: MP30/5/1/2/15389PR Protocol and Chance Fossil Find is included. The applicant, Baberton Mines (Pty) Ltd proposes to prospect an area 13 km north east of Baberton and adjacent to the Sheba Mine over a five-year period divided into five phases. Only the third phase will use some invasive techniques. A maximum of 12 holes will be drilled to a depth varying between 290-335 m. on 0.04 hectares. Four roads will access the drill sites. A total area of 0.19 hectares will be disturbed. The aim is to identify additional mineral resources for the existing Sheba mine such as gold, silver and verdite of the Kimberley Reef. Recommendation This letter serves as a Letter of Exemption. It is in compliance with The Minimum Standards for Palaeontological Components of Heritage Impact Assessment Reports, SAHRA APMHOB, Guidelines 2012. The development is underlain by the Baberton Supergroup. It has a Low Palaeontological Sensitivity, therefore there is a low possibility that significant fossils will be present in the bedrock of these geological units (Groenewald and Groenewald 2014*). The drilling of the 12 holes may grant palaeontologists an opportunity to investigate and document micro stromatolites and the presence of cyanobacteria if found during the investigation phase. The project does exceed the triggers in Section 3 of the National Heritage Resources Act, Act No: 25 of 1999 of listed activities. The drilling will take place in the Moodies Group. -

Palaeontological Field Assessment of the Proposed Swaziland-Mozambique Border Patrol Road and Mozambique Barrier Structure
PALAEONTOLOGICAL FIELD ASSESSMENT OF THE PROPOSED SWAZILAND-MOZAMBIQUE BORDER PATROL ROAD AND MOZAMBIQUE BARRIER STRUCTURE Prepared for: Royal Haskoning DHV Royal HaskoningDHV (Pty) Ltd trading as Royal HaskoningDHV Reg No. 1966/001916/0 Building No. 5 Country Club Estate 21 Woodlands Drive, Woodmead, 2191 PO Box 867, Gallo Manor, 2052, Gauteng, South Africa 05 February 2018 Prepared by: BANZAI ENVIRONMENTAL (PTY) LTD EXECUTIVE SUMMARY Royal Haskoning DHV has appointed Banzai Environmental (Pty) Ltd to undertake a Palaeontological Impact Assessment (Phase 1) assessing the palaeontological impact of the proposed Swaziland- Mozambique Border Patrol Road and Mozambique Barrier Structure. According to the National Heritage Resources Act (Act No 25 of 1999, Section 38), a palaeontological impact assessment is required to detect the presence of fossil material within the proposed development footprint and to evaluate the impact of the construction and operation of the barrier on the palaeontological resources. The proposed project and base camp is underlain by various sedimentary rocks of which the Quaternary and the Undifferentiated Karoo has a high Palaeontological sensitivity and the Zululand Group which has a very high palaeontological sensitivity. The various intrusive rocks have an igneous origin and is thus unfossiliferous and has a zero palaeontological sensitivity. As part of the Palaeontological Impact Assessment, a field-survey of the development footprint was conducted in February 2018 to assess the potential risk to palaeontological material in the proposed footprint of the development. A physical field-survey of the proposed development and camping site was conducted on foot and by vehicle and during this field survey, no fossiliferous outcrops were found in the development footprint. -

Palaeontological Technical Report for Kwazulu-Natal
PALAEONTOLOGICAL TECHNICAL REPORT FOR KWAZULU-NATAL 31 October 2012 Prepared by: Dr. Gideon Groenewald EXECUTIVE SUMMARY The geological history of Kwazulu-Natal covers over 3100 million years of Earth history. Rocks, containing fossils or traces of fossils provide information about the palaeo-environments that existed in the past and the fossil history is therefore part of the Natural Heritage of the Province. The aim of this report is to ensure a better understanding of the fossil heritage in South Africa and to make it clear that fossils are not restricted to the Main Karoo Basin. Although metamorphic provinces are usually non- fossiliferous, low grade meta-sediments of a localized occurrence in the Pongola Group contain good examples of bio-sedimentary stromatolites. Most fossils are hidden in the bedrock and developers will only be able to assess specific reference to fossils once the topsoil has been removed and excavation has exposed the bedrock. The report presented here must be used in conjunction with published geological maps and as such can be used by heritage and environmental assessment practitioners as well as private developers, to evaluate the potential impact of proposed developments on fossil heritage of the province. Rock units are ranked in terms of its palaeontological sensitivity according to a three-point scale, from which the appropriate action to be taken (if any) before or during development can be inferred. Present legislation makes provision for the protection of fossil heritage as part of the National Heritage legislation. Despite the comparatively good legal protection offered to palaeontological heritage in South Africa by the current legislation, hitherto this aspect of natural heritage has been largely ignored by developers and professional heritage managers alike, mainly due to confusion between palaeontological and archaeological heritage. -
The Witwatersrand Basin, South Africa: Geological Framework and Mineralization Processes
ORE GEOIDGY REVIEWS ELSEVIER Ore Geology Reviews 10 (1995) 67-94 The Witwatersrand Basin, South Africa: Geological framework and mineralization processes Laurence J. Robb *, F. Michael Meyer i Department of Geology, University of the Witwatersrand, Private Bag 3, Wits 2050, South Africa Received 19 December 1994; accepted 19 June 1995 Abstract The Witwatersrand Basin formed over a period of 360 Ma between 3074 and 2714 Ma. Pulses of sedimentation within the sequence and its precursors were episodic, occurring between 3086-3074 Ma (Dominion Group), 2970-2914 Ma (West Rand Group) and 2894-2714 Ma (Central Rand Group). Detritus was derived from a mixed granite-greenstone source of two distinct ages; the first comprises Barberton-type greenstone belts and granitoids > 3100 Ma old, and the second consists of the greenstone belt-like Kraaipan Formation and associated granitoids < 3100 Ma old. Subsequent granitoid plutonism was episodic and coincided with hiatuses in sediment deposition, but continued throughout the evolution of the basin. Many of the provenance granitoids are characterized by hydrothermal alteration, are geochemically anomalous with respect to Au and U, and may represent viable source rocks for palaeoplacer mineralization. Tectonically, the basin evolved in response to processes occurring within a Wilson cycle, associated with the encroachment and ultimate collision of the Zimbabwe and Kaapvaal cratons. Metamorphism of the Witwatersrand Basin occurred at ca. 2500, 2300 and 2000 Ma. The first two events coincided with the progressive loading of the basin by Ventersdorp and Transvaal cover sequences, whereas the last reflects intrusion of the Bushveld Complex and/or the Vredefort catastrophism. Mineralization is concentrated in the conglomerates of the Central Rand Group and is represented by a complex paragenetic sequence initiated by early accumulation of detrital heavy minerals. -

This is reflected in general statistics showing that only 13 % of the nation’s total water supply originate from groundwater. However, because of the highly distributed nature of the water demand in rural and informal peri-urban settlements, regional schemes are, in most instances, not economically feasible. -
Limpopo Fossil Heritage
SAHRA PALAEOTECHNICAL REPORT PALAEONTOLOGICAL HERITAGE OF LIMPOPO en.wikipedia.org/wiki/Glossopteris Dr Gideon Groenewald Cell: (082) 339-9202 David Groenewald Cell: (083) 469-4696 Logistical Support: Sue Groenewald Cell: (082) 339 9202 PO Box 360, Clarens, 9707 ([email protected]) (Copyright: March 2014) GENERAL INTRODUCTION The core purpose of this SAHRA palaeotechnical report (PTR) is to briefly but comprehensively document the palaeontological heritage resources in South Africa in an accessible and useful format. Following the request by SAHRA, the report is presented in the form of two sections. The first section outlines the general geological history of South Africa and the second section provides a more detailed, geological history of the Free State, Gauteng, North West, Limpopo and Mpumalanga Provinces with specific reference to the palaeontological sensitivity of geological formations and their importance to the development of life through 3600 million years of time in Earth history. The first section summarises the geological history of South Africa and gives a very brief description of the six major events that shaped the Earth over time. The known and predicted fossil heritage within all the major fossiliferous stratigraphic units (formations, groups etc) that crop out in South Africa are presented on a map that relates directly to the composite geological map of South Africa where mapping was done on a 1:250 000 scale. The palaeontological sensitivity of geological units was allocated sensitivity ratings on a five point scale: very high sensitivity, high sensitivity, moderate sensitivity, low sensitivity and very low sensitivity (Table 1). When used in conjunction with published geological maps, this report can be used by heritage managers and environmental impact assessors, as well as private developers, to rapidly evaluate the potential impact of proposed developments on fossil heritage.
