Capsule Geology

A 30 to 120 metre thick Lower Permian bed of limestone extends northeasterly for 3.1 kilometres along the northwest side of the Skeena River, 21 kilometres southwest of Terrace. The bed is under- lain by undefined metamorphic rocks of amphibolite facies and over- lain by metamorphosed flows, tuffs and breccias of the Telkwa (?) Formation. The bed strikes 050 to 060 degrees and dips 68 to 80 degrees northwest. Several cross faults have segmented the bed. The limestone is extensively fractured and intruded by a few narrow dykes.

The bed is composed of brownish to greenish and bluish grey to white, coarse grained limestone interbedded with lenses of greenstone and mica schist. Disseminated pyrite and flakes of mica are sometimes present. The quality of the limestone varies considerably from place to place. A chip sample taken across 9.75 metres of white limestone exposed in a quarry face contained 48.9 percent CaO, 4.4 percent MgO, 2.5 percent acid insolubles and 0.35 percent Fe2O3 (EMPR Annual Report 1954, p. 181 - Sample 1). A sample taken across 19.5 metres of limestone 67 metres northeast of the quarry contained 53.10 percent CaO, 1.6 percent MgO, 1.2 percent acid insolubles and 0.14 percent Fe2O3 (EMPR Annual Report 1954, p. 181 - Sample 4).

Limestone was produced from a quarry on Lot 4510, 650 metres northeast of the Shames River between 1953 and 1956 for the Columbia Cellulose pulp mill at Port Edward. A total of 15,664 tonnes of limestone was quarried.
