Abstract
This study focusses on the stratigraphy, sedimentology and petrography of the No. 2 depositional sequence in the northern portion of the Permian Highveld Coalfield, Karoo Basin, South Africa. A database comprising 7 000 vertical boreholes was utilised to create series of elevation, thickness, quality and petrographic distributions (called grids) across a 4 500 km2 study area. The primary aim of this study is to develop a palaeoenvironmental and depositional model for the No. 2 depositional sequence, from the base of the Dwyka Group up to the top of the No. 2 Coal Seam (C2 Seam). This study provides a sub-regional database of the C2 Seam, its physical attributes (proximate analyses), general petrographic composition and overall distribution of the coal relative to its interpreted depositional environment, should this seam ever be mined. An investigation of this scale has never been done before in the Highveld Coalfield...
