NC Geologic History

Blue Ridge Belt  This 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 Belt  The 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 Belt  This belt consists mostly of igneous rocks such as granite, diorite and gabbro.  These are million years old.

Carolina Slate Belt  This belt consists of heated and deformed volcanic sedimentary rocks.  It was the site of oceanic volcanic islands about million years.ago

Eastern Slate Belt  This belt contains slightly metamorphosed volcanic and sedimentary rocks.  The metamorphic rocks, million years old, are intruded by ~300 million year old, granite rocks.

Coastal Plain  The 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. %20figures.pdf
