Geochemical and geochronological data from the LeMay Group, Antarctic Peninsula
Riley, Teal
British Geological Survey - National Geoscience Data Centre (UKRI/NERC)
(2022)
The files include full analytical details and datasets from the laboratories used for the acquisition of U-Pb zircon geochronology, Lu-Hf isotope geochemistry and 40Ar/39Ar analysis of detrital white mica. Also included are a list of all the published datasets used in the construction of the MDS and ridge plots for detailed regional comparisons. The data were collected in the interval January 2021 to March 2022 across a number of laboratories: Stockholm, University College London, British Geological Survey, Trinity College Dublin, Australian National University (U-Pb zircon geochronology); Open University (40Ar/39Ar analysis) and British Geological Survey (Lu-Hf isotopes). The analyses were conducted by Teal Riley (Stockholm, British Geological Survey), Ian Millar (Australian National University), Andrew Carter (University College London), Joaquin Bastias (Trinity College Dublin), Craig Storey (Open University). The analyses were conducted to examine the provenance and depositional history of the accretionary LeMay Group complex of Alexander Island.
