The Central Atlantic Magmatic Province (CAMP) is defined by tholeiitic basalts that crop out in once-contiguous parts of North America, Europe, Africa, and South America and is associated with the breakup of Pangea. $^{40}$Ar/$^{39}$Ar and paleomagnetic data indicate that CAMP magmatism extended ove...
