This MSc study of the coal-bearing Karoo strata in the Central Kalahari Sub-basin attempts to work out the dynamics of coal depositional environments, in particular the forces responsible for changes in the accommodation space (e.g., subsidence vs. sedimentation rates). This is hoped to be achieved by a detailed review of the temporal and spatial stratigraphic variation of the coalbearing successions, including the analysis of facies changes based on over 800, widely distributed borehole records (e.g., core descriptions, gamma and spontaneous potential logs), field observations and palaeocurrent measurements. Utilizing RockWorks®, the subsurface data will be processed and results expressed in form of multi-log plots, cross-sections for correlation purposes (e.g., fence diagrams) and various maps (e.g., clastic to coal ratio contours, coal seam and sandstone isopach maps).
