Data on the arc magmatism developed in the Antarctic Peninsula and Patagonia during the Late Triassic–Jurassic: A compilation of new and previous geochronology, geochemistry and isotopic tracing results

We present the results of U-Pb zircon dating conducted using laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS), isotopic tracing analyses Hf in and Sr-Nd whole-rock major oxides, trace element abundances 12 plutonic volcanic rocks on Antarctic Peninsula.
