Abstract:
A regional synthesis of 3,350 km of multichannel seismic-reflection profiles over the Georges Bank area reveals that subsidence concentrated in several areally restricted rift basins of Early Jurassic age and older. Beneath the northwestern half of Georges Bank area, these small sub-basins form narrow grabens within a structurally shallow platform (4 km deep). Beneath the southern half of Georges Bank and Nantucket Shoal area are three deep sub-basins containing more than 10 km of sediments. The sedimentary fill is divided into six seismic units that reveal a change from an older, thick sequence of rift-filling (synrift) continental and evaporitic deposits (0 to 8 km thick) of Late Triassic to Early Jurassic age, to younger, more widespread open-marine shelf seque ces of carbonate and clastic sedimentary rocks of Jurassic and younger ages.
