The first dataset is a compilation of published zircon U-Pb ages of igneous rocks associated with the Mesozoic-Cenozoic North American Cordilleran arc. The compilation of igneous zircon data includes 1,492 U-Pb ages from the Peninsular Ranges, Sierra Nevada, Idaho, Boulder, and Coast Mountains batholiths, as well as spatially and temporally associated igneous bodies. The second dataset is a compilation of published detrital zircon U-Pb ages from Jurassic to Paleocene strata preserved in forearc and foreland basins of the North American Cordillera. The compilation of detrital zircon data includes 101,595 U-Pb ages from 827 detrital zircon samples.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9E5INN9", "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.60119c97d34e162231fed419.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_60119c97d34e162231fed419", "keyword": ["Cenozoic Era", "Cretaceous Period", "Jurassic Period", "Mesozoic Era", "Paleocene Epoch", "Paleogene Period", "USGS:60119c97d34e162231fed419", "basin analysis", "detrital zircon", "geology", "sedimentology", "tectonics"], "modified": "2021-07-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-128.93554687344, 26.862890310604, -100.63476562458, 51.261641061764", "theme": ["geospatial"], "title": "Compilation of in situ and detrital zircon U-Pb ages for the Jurassic-Paleocene North American Cordillera (28-50 degrees north)"}
