Capsule Geology

Various exposures of limestone occur along Highway 1 (Trans-Canada Highway), 1.6 to 3 kilometres east of Sorrento. These outcrops are situated near the west end of a 27 kilometre long, west- trending belt of limestone and schist of the lower Paleozoic Sicamous Formation (Mount Ida Group).

The limestone is fine grained and dark grey. Micaceous and graphitic partings give the limestone a platy appearance. Numerous white calcite veinlets and white quartz veins cut the rock. Scattered patches of pyrite are also present.

A sample composed of chips taken at 6.1-metre intervals along a 259 metre long roadcut, 3 kilometres east of Sorrento, analysed 46.44 per cent CaO, 0.90 per cent MgO, 11.84 per cent insolubles, 1.20 per cent R2O3, 1.29 per cent Fe2O3, 0.04 per cent MnO, 0.021 per cent P2O5, 0.04 per cent sulphur and 38.77 per cent ignition loss (Minister of Mines Annual Report 1960, page 144, Sample 1).
