Geological fieldwork was carried out in the Hudson Mountains during the 2005/6 and 2019/20 Antarctic summers to help understand the glacial history of the Pine Island Glacier region of West Antarctica. To accurately determine the crystallisation age of a suite of granitoid glacial erratics, we conducted a detailed analysis of zircon U-Pb geochronology. The dataset here provides U-Pb zircon geochronology data for 10 rock samples, collected from the Hudson Mountains. The data were collected in November 2024 at University College London. The analyses were conducted by Andrew Carter (University College London).
