Abstract
Sillimanite has been found throughout a long belt in the Piedmont of South Carolina and Georgia. The host rock is a quartz mica schist, which presumably was originally an arenaceous sediment containing considerable aluminum. Sillimanite has been formed from biotite by the action of granite intrusions. Some deposits show promise of commercial value.
