Geology
The Queenstown area is in the Burgersdorp formation of the Tarkastad sub group, in the upper beaufort group triasic in age in the karoo super group. The lithology is red mudstone 1-10m rich layers and surb ordinate 1m-2m rich sand stone layers deposited by meandering rivers in the flood plain in an oxidising environment gradually filling the Karoo basin. The formation reaches thickness of 600m in the Queenstown and Lady Frere area (S.gcobo). Numerous Dolerite dykes and ring structures intruded the area creating good localities for ground water exploration.
