Limestone (Industrial) Refer also Dolomite (Industrial)

The flat-lying fossiliferous limestone unit is approximately 30 m thick. Overburden comprises 3–4 m of calcrete, the lower 2 m of which is high in clay, which also infills solution cavities and pipes extending up to 20 m below the surface. The limestone is extracted by ripping and dozing, although some blasting of hard bands is required.
