Geochemical and geochronological data from the Falkland Islands, 2023-2024

(2024)
Geological fieldwork was carried out in the Falkland Islands in March 2022 to help understand the depositional history and provenance of Late Permian sedimentary rocks of East Falkland. To accurately determine their depositional age and precise provenance we conducted a detailed analysis of zircon geochronology and geochemistry. The files provided here 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 November 2023 to July 2024 across a number of laboratories: University College London and Australian National University (U-Pb zircon geochronology); British Geological Survey (Lu-Hf isotopes). The analyses were conducted by Ian Millar (Canberra, British Geological Survey) and Andrew Carter (University College London). The analyses were conducted to examine the provenance and depositional history of the sedimentary successions of the Falkland Islands.
