The files include full analytical details and datasets from the laboratories used for the acquisition of U-Pb zircon geochronology and Lu-Hf isotope geochemistry. The data were collected in the interval September 2022 to January 2023 across a number of laboratories: Stockholm, University College London and Australian National University (U-Pb zircon geochronology); British Geological Survey (Lu-isotopes). The analyses were conducted by Teal Riley (Stockholm, British Geological Survey), Ian Millar (Australian National University) and Andrew Carter (University College London). The analyses were conducted to examine the provenance and depositional history of the Fossil Bluff Group fore arc basin sediments of Alexander Island.
