The geochemical data comprise whole-rock major oxide and trace element abundances in 111 samples. Pairs of images in plane-polarized light and cross-polarized light are included for 90 thin sections. Step-heated 40Ar/39Ar analyses of mineral separates/concentrates from 10 different hand samples are also included and comprise 8 analyses of muscovite/sericite, 3 analyses of potassium feldspar, and 2 analyses of actinolite.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1KR5E7F", "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.6875053dd4be025f81987b93.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6875053dd4be025f81987b93", "keyword": ["40Ar/39Ar", "Bascom Argon Dating Laboratory", "Connecticut", "FBGC", "Geochemistry", "Geochronology", "New England", "Petrogenesis", "Petrography", "U.S. Geological Survey", "USGS", "USGS:6875053dd4be025f81987b93", "geoscientificInformation"], "modified": "2025-08-25T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-73.1004, 41.1837, -72.9550, 41.3765", "theme": ["geospatial"], "title": "Geochemistry, thin section images, and 40Ar/39Ar isotopic data of selected bedrock samples in the Orange-Milford Belt, Connecticut"}
