The geology of North Carolina includes ancient Proterozoic rocks belonging to the Grenville Province in the Blue Ridge.The region experienced igneous activity and the addition of new terranes and orogeny mountain building events throughout the Paleozoic, followed by the rifting of the Atlantic Ocean and the deposition of thick sediments in the Coastal Plain and offshore waters.
The Albemarle Group is a geologic group in North Carolina composed of metamorphosed mafic and felsic volcanic rock, sandstone, siltstone, shale, and mudstone. [1] It is considered part of the Carolina Slate Belt and covers several counties in central North Carolina. It preserves fossils dating back to the Ediacaran period in the Floyd Church ...

The Uwharries were once a coastal mountain range; [2] isostasy has slowly raised the eastern seabed until today they lie in the Piedmont of North Carolina over 150 miles (240 km) from the coast. Formed approximately 500 million years ago by accretion along the Gondwanan tectonic plate, they are thought to have once peaked at some 20,000 feet ...
The Sanford Formation is a Late Triassic -age geologic formation in North Carolina. It is mainly found in the Sanford sub-basin of the Deep River Basin, the southernmost of the large Mesozoic basins forming the Newark Supergroup. It is the highest unit of the Chatham Group, overlying the dark lake and swamp sediments of the Cumnock Formation.
Shaded relief map of the United States, showing 10 geological provinces. The richly textured landscape of the United States is a product of the dueling forces of plate tectonics, weathering and erosion. Over the 4.5 billion-year history of the Earth, tectonic upheavals and colliding plates have raised great mountain ranges while the forces of ...
