Deep River Basin
Location of the Deep River Basin
The Deep River Basin is an ancient rift basin in the Piedmont of North Carolina. It formed in the Late Triassic during the initial breakup of the supercontinent Pangea. The formation of the basin preceded a much larger volcanic event known as the Central Atlantic magmatic province (CAMP), one of the largest eruptions in Earth's history. The Deep River Basin is one of a series of Late Triassic–Early Jurassic rift basins along the east coast of North America; collectively they are called the Newark Supergroup.
