Provinces of the North American craton
1) The crust of these units likely formed from mountain building along
convergent plate margins where magma intrusion and metamorphism of thickened crust are common.
2) Much uplift, erosion, and isostatic adjustment occurred to expose the metamorphic and plutonic rocks at the surface before they were buried by younger sedimentary rocks.
