TOP/LEFT: Extent of Central Atlantic Magmatic Province on a reconstruction of Pangea at ~200 million years ago. CAMP-related igneous rocks are present in eastern North America, northeastern South America, western Africa and western Europe. From McHone( 2000). BOTTOM/RIGHT: Map of eastern North America showing the extent of CAMP-related dikes (based on McHone, 2000; McHone et al., 2005, 2022), subsurface basalt and diabase (Chowns and Williams, 1983; Heffner et al., 2012), and plutons of the White Mountain Magma Series. Inset shows the distribution of CAMP on a reconstruction of Pangea (based on Olsen, 1999; Marzoli et al., 1999). Figure modified from Withjack et al. (2022).
