General Geology. 
Three distinct geological provinces (see fig. 2) are represented in 
the Georgia-South Carolina region: (1) the coastal-plain belt; (2) the 
crystalline belt; (3) the paleozoic area. 
The coastal-'plain belt .— The southern three fifths of Georgia and 
the eastern half of South Carolina lie within the coastal-plain belt, 
which extends from New Jersey around the Atlantic and Gulf coasts 
and into Mexico. Composed of nearly horizontal Cretaceous and 
later sediments, unmetamorphosed and but little consolidated, these

coastal-plain deposits contrast strongly with the rocks of the crystal¬ 
line belt, which they overlap on the northwest. 
The crystalline belt .— Crossing western South Carolina and north¬ 
ern Georgia is the southern extension of the crystalline belt, com¬ 
posed chiefly of much crumpled gneisses and schists, the strike of 
whose foliation is northeast-southwest. Associated with these rocks
