U-Pb Isotopic Data and Dates of Zircon from the Western Upper Peninsula of Michigan and Northern Wisconsin, United States
This dataset contains U-Pb isotopic data and associated dates of zircon from sedimentary and metamorphic rocks collected from the western Upper Peninsula of Michigan and northern Wisconsin, United States. The samples were collected as part of geological mapping and research conducted from 2019 to 2023 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon grains were separated and analyzed by GeoSep Services (GSS) from 2020 to 2024 using laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques.
