The Iron Mask batholith is an earliest Jurassic (207±3 Ma; Ghosh 1993), composite alkalic intrusion lo-cated approximately 10 kilometres southwest of Kam-loops, British Columbia (Figure 1). It lies in the southern part of the Quesnel Terrane, a volcanic arc that lay somewhere offshore of North America during the Late Triassic (Souther, 1992). The batholith is an elongate, northwest-trending body approximately 22 kilometres long and 5 kilometres wide, and intrudes volcanic and sedimentary rocks of the Upper Triassic Nicola Group (Preto, 1968). The batholith is exposed in the Iron Mask pluton to the southeast and in the smaller Cherry Creek pluton to the northwest which are separated by a graben of down-faulted Eocene Kamloops Group volcanic and sedimentary rocks (Kwong, 1987).
