The dataset accompanies the publication \"An empirical test of Maximum Depositional Age through paired LA-ICP-MS and CA-ID-TIMS detrital zircon analysis: implications for the \"Nevadan orogeny\" in the Sierra Nevada foothills, California, U.S.A.\", as well as planned future publications in this region. U-Pb detrital zircon data were used for this study to generate maximum depositional ages (MDAs) based on current established practices to be compared to CA-ID-TIMS dates collected from the same samples. The geochronology data collected from these samples provides an example of the potential for sub-million-year resolution of contemporaneous igneous and sedimentary systems during deformation and clarifies the timing of regional deformation that defines the local \"Nevadan orogeny\".", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1AJGUVW", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.683dd74ed4be0234870fc9c5.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_683dd74ed4be0234870fc9c5", "keyword": ["Bear Mountains", "California", "David Gulch", "Detrital Zircon", "GGGSC", "Geochronology", "Geology, Geophysics, and Geochemistry Science Center", "LA-ICPMS", "Laser-Ablation Inductively-Coupled Plasma Mass Spectrometry", "MRP", "Microbeam Laboratory", "Mineral Resources Program", "Radiometric Dating", "SEM-cathodoluminescence", "Salt Spring Valley Reservoir", "Sedimentary Rocks", "Sierra Nevada", "Thorium", "U-Pb", "U.S. Geological Survey", "USGS", "USGS:683dd74ed4be0234870fc9c5", "Uranium", "Uranium-Lead analysis"], "modified": "2025-09-23T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-120.7234, 37.3781, -120.1268, 38.0274", "theme": ["geospatial"], "title": "U-Pb detrital zircon geochronology data for Jurassic terranes in the western Sierra Nevada, CA"}
