The data set reports the Re-Os isotopic composition, Re-Os age and select trace element contents of the mineral molybdenite associated with ore deposits in the United States, Canada, and Australia. These data were collected using the LA-ICP-MS/MS technique. Additionally, analyses for Re-Os isotopic composition and select trace element contents are reported for several organic-rich black shale units from the United States, Australia, and China.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13ZTY3I", "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.63a0b944d34e0de3a1f277cb.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_63a0b944d34e0de3a1f277cb", "keyword": ["Australia", "Bingham Canyon", "Canada", "Geology, Geophysics, and Geochemistry Science Center", "Henderson Mine", "Mineral Resources Program", "Os", "Re", "Re-Os", "U.S. Geological Survey", "USGS:63a0b944d34e0de3a1f277cb", "United States", "black shale", "geochronology", "geoscientificInformation", "mass spectrometry", "molybdenite", "radiometric dating", "trace elements"], "modified": "2026-08-14T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-137.8125, -45.0890, 165.9375, 60.9304", "theme": ["geospatial"], "title": "Re-Os isotopic compositions of world-wide occurrences of the mineral molybdenite and black shale by LA-ICP-MS/MS."}
