Capsule Geology

The Vernon Limestone deposit is located 2 kilometres west of Vernon.

Sedimentary rocks of the Devonian to Triassic Harper Ranch Group are in probable unconformable contact with Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. Middle Jurassic granitic plugs intrude these rocks. Outliers of Eocene Kamloops Group volcanic rocks occur.

The Harper Ranch Group hosts a Permian limestone lens which was quarried for industrial use. The lens comprises an 800 metre diameter mass of medium to dark grey, medium-grained limestone with veinlets and lenses of quartz and calcite. Sampling returned 49.9 per cent CaO, 2.2 per cent MgO, 0.62 per cent Fe2O3 and insolubles at 5.1 per cent (Minister of Mines Annual Report 1961, pp. 147-148).

Minor production for lime was discontinued due to the poor quality of the limestone.
