Geologic setting

Geologic description

Minor molybdenite occurs in a hornfels zone adjacent to a small granitic stock; samples of the hornfels also contain up to 75 ppm tungsten (Doyon Limited, 1987). The general area is underlain by the Lower Cambrian to Proterozoic, Tindir Group, which is predominantly carbonate, quartzite, argillite, and subordinate volcanic rocks. The Tindir Group rocks have been thrust over undivided cherty limestone, shale, and other clastic rocks of Triassic to Missippian age (Dover, 1994).
