Looking Glass Dome. 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 ...

Despite the fact that North Carolina has hundreds of miles of beachfront territory, due to the Outer Banks and swampland along the coast the state lacks a good natural harbor. As such, North Carolina never developed a major port city as did neighboring states such as Georgia (Savannah), South Carolina (Charleston), and Virginia (Norfolk).
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.
Powerful geologic forces formed rifts in North Carolina during the Triassic period. Clams, crustaceans, and fishes lived in local lakes and rivers. On land, the local flora included conifers and cycads. [2] The early Mesozoic plant life of North Carolina was very similar to that of neighboring Virginia.
Geologic map of North America. The geology of North America is a subject of regional geology and covers the North American continent, the third-largest in the world. Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the continent. The divisions of regional geology are ...
