Picritic basalt is exposed in the Intermontane Belt in the southern part of the Quesnellia Terrene, south-central British Columbia (Figure 1). It is found in four localities in the Kamloops Lake area (Figure 2): as small pods within the Early Jurassic Iron Mask batholith; on an isolated knoll near Jacko Lake just outside the southwestern margin of the Iron Mask batholith; near Carabine Creek on the north side of Kamloops Lake; and north of Pass Lake near Watching Creek. These rocks are olivine±clinopyroxene-porphyritic, occasionally serpentinized and exhibit volcanic textures. They contain extremely high MgO, anomolously low AI2O3, low TiO2 and are enriched in chromium and nickel.
