Abstract/Summary

We present the results of U-Pb zircon dating conducted using laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS), isotopic tracing analyses of Hf in zircon and Sr-Nd in whole-rock and whole-rock major oxides, and trace element abundances of 12 plutonic and volcanic rocks present on the Antarctic Peninsula. The dataset is presented in combination with the results of previous studies conducted in both Patagonia and the Antarctic Peninsula. These results were filtered for concordant 206Pb–238U zircon ages and topology of the 40Ar/39Ar age spectra. These results may be useful for researchers studying the geological evolution of southern Gondwana, West Antarctica or Patagonia. The interpretation of this dataset is found in the co-submitted paper by Bastias, et al. (2021a) titled ‘A revised interpretation of the Chon Aike magmatic province: active margin origin and implications for the opening of the Weddell Sea’.
