Lu-Hf isotope evidence for the provenance of Permian detritus in accretionary complexes of western Patagonia and the northern Antarctic Peninsula region
Lu-Hf isotope data are presented for dated Permian zircon grains from six samples of the latest Palaeozoic to Jurassic low-grade metasedimentary rocks of western Patagonia and the northern Antarctic Peninsula, as well as from potential source rocks in the North Patagonian Massif. The results for the metasedimentary rocks yield εHf values mostly between -15 and +4 (130 analyses), with a dominant range (more than 85%) of -6 to +1, indicating provenance from Permian magmatic rocks that...[Show more]
