Resumo

Twenty-two new K–Ar age determinations are reported for the plutonic rocks between Hope, B.C. and the 49th parallel. Ages ranging from 103 m.y. to 16 m.y. suggest an extension in southern British Columbia of Mesozoic plutonism into Late Cretaceous time and three brief and well-defined Tertiary plutonic events.
