NC Geologic History

Blue Ridge BeltThis mountainous region is

composed of rocks from over 1 billion to ~1/2 billion years old.

Mixture of igneous, sedimentary and metamorphic rock has been squeezed, fractured, faulted and twisted into folds.

Inner Piedmont BeltThe metamorphic rocks here range

from 500 to 750 million years in age.The Brevard fault zone forms the

boundary between the Blue Ridge and Inner Piedmont belts.

Charlotte BeltThis belt consists mostly of igneous rocks such as granite, diorite and gabbro.

These are 300-500 million years old.

Carolina Slate BeltThis belt consists of heated and deformed volcanic sedimentary rocks.

It was the site of oceanic volcanic islands about 550-650 million years .ago

Eastern Slate BeltThis belt contains slightly metamorphosed volcanic and sedimentary rocks.

The metamorphic rocks, 500-600 million years old, are intruded by ~300 million year old, granite rocks.

Coastal PlainThe Coastal Plain is a wedge of mostly marine sedimentary rocks that gradually thickens to the east.

It is the largest geologic belt in the state, covering ~ 45% percent of the state’s land area.
