In the United States the principal mica-bearing regions are the Blue Ridge and Piedmont provinces of North and South Carolina. North Carolina produces about 60% of the total US output, derived principally from alaskite in the Spruce Pine district which contains 60% feldspar, 25% quartz, and 15% muscovite.
