The Colorado Mineral Belt (CMB) is an area of ore deposits from the La Plata Mountains in Southwestern Colorado to near the middle of the state at Boulder, Colorado, and from which over 25 million troy ounces (778 t) of gold were extracted beginning in 1858. [2]
The Colorado Province took shape as a mobile belt—an area of thinner, orogeny related continental crust lacking the deep "keel" of rock, which stabilized the neighboring Wyoming Craton and other cratons like it. Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record.

Uinta and Piceance Basins geologic map Stratigraphic column. The Piceance Basin is a geologic structural basin in northwestern Colorado, in the United States.It includes geologic formations from Cambrian to Holocene in age, but the thickest section is made up of rocks from the Cretaceous Period.
