Provenance of Neoproterozoic to upper Cretaceous sedimentary rocks, eastern Greenland: Implications for recognizing the sources of sediments in the Norwegian Sea

The Hf isotopic compositions of detrital zircons suggest that Eoarchean crust derived from a source with chondritic Lu/Hf ratios at ca. 3900-3700 Ma contributed to zircon-forming processes in the source area for the eastern Greenland sandstones until ca. 2300 Ma. The Caledonian orogeny in this area was probably a crust reworking event with a limited contribution from depleted mantle.
