The dated samples represent four different mining districts spanning the entire country from the village of Pitk\u00e4ranta in the west (31\u00b0 E Longitude) to the Merekskoe Deposit in the Russian Far East (134\u00b0E Longitude). The samples were recovered from a variety of host deposit types that range from the Proterozoic to Phanerozoic. Cassiterite (in the form of mounted loose grains) was prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS) system at the USGS in Denver, Colorado from February 2017 to October 2019.  This data supports the following associated publication:  Neymark, L.A., Larin, A.M., and Moscati, R.J., 2021, Pb-Pb and U-Pb dating of cassiterite by in situ LA-ICPMS: Examples spanning ~1.85 Ga to ~100 Ma deposits in Russia and implications for dating Proterozoic to Phanerozoic tin deposits, Minerals.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9HK0RL5", "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.612533d8d34e40dd9c03f29c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_612533d8d34e40dd9c03f29c", "keyword": ["GGGSC", "Geology, Geophysics, and Geochemistry Science Center", "LA-ICP-MS", "MRP", "Mineral Resources Program", "Pitk\u00e4ranta", "Russia", "Siberia", "U-Pb", "U.S. Geological Survey", "USGS", "USGS:612533d8d34e40dd9c03f29c", "cassiterite", "geochronology", "geoscientificInformation", "laser ablation inductively coupled plasma mass spectrometer", "lead", "mineral deposits", "thorium", "uranium", "uranium-lead analysis"], "modified": "2021-10-21T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "31.41, 51.317, 134.718, 61.681", "theme": ["geospatial"], "title": "Pb-Pb and U-Pb data of Proterozoic to Phanerozoic cassiterite deposits in Russia"}
