What this report found

Electrical and electromagnetic ground surveys were run over a Waterberg profile with borehole logs and three dimensional seismic data as control, to test whether cheaper methods can match seismic reflection for locating coal and faults. Resistivity tomography at two electrode spacings, frequency and time domain electromagnetics, controlled source audio magnetotellurics and magnetics were all acquired. Results are preliminary.

Petrochemical Characterization of Dolerites and Their Influence on Coal in the Witbank Highveld Coalfield, South Arica

Johannes Jochemus du Plessis

2008

Masters study of dyke and sill intrusions at collieries in the Witbank and Highveld coalfields, using thin section petrography and X-ray fluorescence, for exploration geologists.

What this report foundDolerites in the study area differ in mineral content, geometry, thickness, grain size and degree of alteration.

What this report found

Dolerites in the study area differ in mineral content, geometry, thickness, grain size and degree of alteration. Plagioclase textures indicate fractionation at different depths in the crust for the Witbank and Sasolburg intrusions, and the olivine content points to separate magma sources for two of the sills. Fine crystalline dolerite, including chilled margins and bifurcations, alters most readily.
