Capsule Geology

The Layers deposit, in south central British Columbia, is approximately 2.4 kilometres south of the mouth of Whiskey Creek.

The region is underlain by the, generally poorly exposed, Carboniferous to Jurassic Cache Creek Group. The Cache Creek Group is complexly faulted and folded and consists of banded chert, argillite, limestone and chlorite-rich rocks considered to be metabasalt. Chert with interbedded slaty argillite is exposed on the east bank of the Fraser River south of Hargreaves. These rocks are folded about north trending axes and are flat lying or gently dipping.

The building stone produced from the Layers deposit came from chert beds ranging in thickness between 0.6 centimetres and 20.3 centimetres. The chert beds range in color through red, rust, cream, green and dark grey colours. Films and thin interbeds of slaty argillite occur within the chert horizon. During the period 1966 to 1974 a crushing plant produced chips for use as exposed aggregate and stucco dash. No production figures are available.
