Late Cretaceous two-mica granitoids in the Great Basin are closely associated with a characteristic style of lithophile-element (Be, F, W, Mo, Sn, and Zn) mineralization. Previously undescribed in the western United States, this kind of deposit is characterized by greisenlike zones in the intrusions, distinctive F- and Al-rich skarns in carbonate rocks, F-deficient quartz veins in clastic rocks, and distal metal-bearing, quartz-carbonate veins. Mineralization can be extensive, locally reaching economic grades. These occurrences resemble greisen-type ore deposits found in other parts of the world; collectively, they constitute a new metallogenic province in the western United States.
