Basin Inversion

In this video continental crust is first pulled apart during extension and then tectonic forces change direction and the crust is put under compression. What results is first a basin and then an inverted basin.

Relative timing of CAMP, rifting, continental breakup, and basin

Similar structures can be found all along the east coast of North America. These rift basins formed during the breakup of Pangea ~200 Ma. The basins later experienced compression when the North American plate transitioned from rifting to seafloor spreading.
