Capsule Geology

A series of lenticular limestone masses form a discontinuous belt that extends southward from Twin Creek up McKinley Creek to the MCKINLEY mine (082ENE001) for 2.9 kilometres, along the west slope of Franklin Mountain.

The FRANKLIN CAMP LIMESTONE lenses are hosted in greenstone, quartzite, tuff and breccia of the Devonian-Triassic Harper Ranch Group. The carbonate horizon strikes north and dips steeply east. Individual masses outcrop over lengths of up to 1200 metres and vary up to 90 metres in thickness.

The limestone is generally light to dark bluish grey and fine grained. In thin section the rock displays larger calcite grains in a fine grained calcite matrix. Thin sections also reveal crinoid stems and possible fusilinid remains. The limestone is sometimes veined with calcium silicates. Skarn zones containing such minerals are occasionally formed along the margins of some of the limestone bodies.

There is no record of exploration or development of this limestone resource.
