The geologic history of the state began with its assembly during the Yavapai and Mazatzal orogenies 1750 to 1650 million years ago (Mya). This was followed by 200 million years of tectonic quiescence that ended in the Picuris orogeny. This event transformed the New Mexico crust into mature continental crust.
