The Central Atlantic Magmatic Province (CAMP) is defined by tholeiitic basalts that crop out in the once-contiguous parts of North America, Europe, Africa and South America and is associated with the breakup of Pangea. 40Ar/39Ar and paleomagnetic data indicate that CAMP magmatism extended over an area of 2.5 million square kilometers in north and central Brazil, and the total aerial extent of the magmatism exceeded 7 million of square kilometers in a few million years, with peack activity at 200 million years ago. The magmatism coincided closely in time with a major mass extinction at the Triassic -Jurassic boundary
