Popis: It is thought that Atlantic style passive margins have experienced episodes of uplift and volcanism in response to changes in mantle circulation. The authors here employ U-Pb dating of calcite in faults and fractures along the eastern North American margin and find a 40 Myr long period of fracturing and faulting from 115 to 75 Ma.
