Kalaka Mining

Kalaka's limestone is currently being mined near Northam, a town in the Waterberg District Municipality in the Limpopo province, approximately 50 km south of Thabazimbi. Kalaka's deposit is unusual and unique in that it is calcitic limestone, not the more prevalent dolomitic limestone commonly occurring in South Africa.

Limestone

Limestone. Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).

Peak District Geology

Limestone underlies much of the southern Peak District and displays many characteristic features: plateaus dissected by steep valleys and gorges, caves and dry valleys. Further north, large areas of bare rock are found on high ground (famously around Malham), but Derbyshire received a covering of wind blown dust at the end of the ice ages that provided the basis for soils over the whole area.
