GEOLOGICAL OVERVIEW
Geological mapping
•The dip of the beds to westwards at about 15° undulating in places and flattening towards the centre of the basin
•The manganese deposit of the Kuruman District occurs as chemical precipitates. The protore is a laminated, fine-grained calcareous rock carrying about 27% manganese
•The formation consists of banded iron formation, with 3 manganiferous horizons near the base of the zone and calcareous dolomites higher up in the succession.
Regional setting
According to the published 1: 250 000 geological map 2722 KURUMAN, the area is underlain by rocks of the Griquatown – West Sequence, viz dolomite with chert and dolomitic limestone, overlain by banded Iron Formation. Aeolian sand covers the plains.
Local observations
The villages are located near the northern end of a N – S striking range of hills comprised of BIF as mentioned above.
The BIF outcrops immediately outside the perimeter of the crater – like depression deviate from the generally flat lying attitude to dipping at 45 ° to 70 ° towards the depression inside the depression signs of an old borehole generating fine chips of BIF can be seen.
