Triassic-Jurassic rift basins in eastern North America. The map shows the location of the Newark basin and other Triassic-Jurassic rift basins in eastern North America. This compilation includes exposed basins and those basins buried by Coastal Plain and continental-margin sediments. This map also shows the boundary (border) faults of the basins (black lines with ticks) and older Paleozoic faults (green lines with triangles). Modified from Withjack et al. (2020).
