- Karmutsen Formation
The Karmutsen Formation is a
Late Triassic volcanic sequence of tholeiitic pillow basalts and breccias onVancouver Island ,British Columbia ,Canada . It is perhaps the thickest accreted section of anoceanic plateau worldwide, exposing up to 6000 m of basal sediment-sill complexes,basalt ic to picritic pillow lavas, pillowbreccia , and thick, massive basalt flows. The widespread succession of basalts and breccias are part of theInsular Mountains , a large volcanicmountain range that forms Vancouver Island and theQueen Charlotte Islands . InStrathcona Provincial Park , pillow basalts is the most abundant rock unit.
