Abstract

Distinctive lithophile-element (Be, F, W, Mo, Sn and Zn) mineralization is closely associated with at least 7 to perhaps 20 or more late Cretaceous two-mica granitic rocks in the Great Basin. These occurrences are distributed approximately along the axis of the Cordilleran miogeosyncline ranging from east-central California to NW Nevada. This kind of deposit is characterized by greisen- like zones in the intrusions, distinctive F- and Al-rich skarns in the carbonate rocks, F-deficient quartz veins in clastic rocks, and distal metal-bearing, quartz-carbonate veins. Mineralization can be extensive, locally reaching economic grades. Despite lack of B minerals, topaz, and significant Sn, 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.-L.C.H.
