This second part focused on the Eastern Bushveld Complex and discussed the major trends, geometry and age relationship of the various structures within the Complex. The trend surface analysis of the Eastern Bushveld reveals that most of the residual positive structures occur as isolated closures with dome shape and are consistent with the location of the diapiric structures previously identified by geophysical and field mapping techniques.展开更多

This technique was used to analyse over one hundred borehole log data in the Northern Bushveld Complex in order to describe the geometric pattern and trends of the RLS rocks. The results demonstrate the usefulness of this technique in identifying structural features. Regional trends of each of the stratigraphic units reveal the presence of regional structures that were not obvious at the surface. This first part of the paper focused on the Northern Bushveld Complex, while the second and the third part focused on the eastern and western Bushveld limbs respectively.展开更多
