South Carolina
South Carolina spans crystalline Piedmont rocks and the younger sediments of the Atlantic Coastal Plain. This page is a starting point for notable stone types, common minerals, and practical collecting/identification themes across the state.
What to look for
- Piedmont crystalline rocks: gneiss, schist, and granitic intrusions.
- Coastal Plain deposits: sands, clays, and shell-rich sediments that record marine influence.
- Everyday stone uses: aggregates and durable building stone sourced from hard crystalline units.
