Central Atlantic magmatic province

Common card · No. 421112

The Central Atlantic magmatic province (CAMP) is the Earth's largest continental large igneous province (LIP), covering an area of roughly 11 million km2 (4.2 million sq mi). It is composed mainly of basalt that formed before Pangea broke up in the Mesozoic Era, near the end of the Triassic and the beginning of the Jurassic periods. The subsequent breakup of Pangea created the Atlantic Ocean, but the massive igneous upwelling provided a legacy of basaltic dikes, sills, and lavas now spread over a vast area around the present central North Atlantic Ocean, including large deposits in northwest Africa, southwest Europe, as well as northeast South America and southeast North America (found as continental tholeiitic basalts in subaerial flows and intrusive bodies). The name and CAMP acronym were proposed by Andrea Marzoli (Marzoli et al. 1999) and adopted at a symposium held at the 1999 Spring Meeting of the American Geophysical Union. The CAMP volcanic eruptions occurred about 201 million years...
