Tertiary metallogeny of the Rocky Mountains Province, USA

Tertiary ore deposits in the Rocky Mountains physiographic province primarily formed through magmatic-hydrothermal processes associated with shifting tectonics and lithospheric conditions. Important deposit types in the province are calc-alkaline and Climaxtype porphyry; high-, medium-, and low-sulfidation epithermal; alkalic magmatic; carbonate replacement; tungsten skarn and vein; and sandstone uranium. Province wide, there is diachroneity from north to south among both ore-forming and magmatic events.
