U-Pb Isotopic Data and Zircon Age Determinations from the Island of Puerto Rico, United States

This dataset contains U-Pb isotopic data and associated ages of zircons from selected igneous rocks collected from the region surrounding and including the uplands of the United States Territory of Puerto Rico. The samples were collected as part of geological mapping and research conducted during 2018 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon grains were separated and analyzed by GeoSep Services (GSS) in 2019 using laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques.
