Detrital zircon age constraints on the provenance of sandstones on Hatton Bank and Edoras Bank, NE Atlantic
U-Pb dating of detrital zircons shows that the provenance of Cretaceous-Palaeogene sandstones on Hatton and Edoras banks (SW Rockall Plateau) comprises magmatic rocks dated at c. 1800 Ma and c. 1750 Ma, respectively. Their depositional setting, first-cycle mineralogy and unimodal detrital zircon populations suggest that these sandstones are of local origin. The zircon age data are therefore considered to provide constraints on these poorly understood areas of the Rockall Plateau. The U-Pb dates...[Show more]
