The 40Ar/39Ar and electron microprobe data are from samples adjacent to a lower greenschist facies shear zone in western New Hampshire. The geochronology coupled with the electron microprobe data provide a petrochronologic framework for the rocks studied in the manuscript.  Samples collection was supervised by Ryan McAleer, Gregory Walsh, and Peter Valley of the USGS.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9J7I9NW", "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.60099c53d34e162231fb2265.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_60099c53d34e162231fb2265", "keyword": ["40Ar/39Ar", "Claremont, New Hampshire", "FBGC", "Florence Bascom Geoscience Center", "NCGMP", "National Cooperative Geologic Mapping Program", "New Hampshire", "Petrochronology", "Reston Argon Geochronology Laboratory", "Reston Electron Microbeam Laboratory", "U.S. Geological Survey", "USGS", "USGS:60099c53d34e162231fb2265", "geochronology", "geoscientificInformation", "mass spectroscopy", "radiometric dating"], "modified": "2021-01-21T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-72.4, 43.3, -72.2, 43.5", "theme": ["geospatial"], "title": "Electron microprobe and 40Ar/39Ar isotopic data from west-central New Hampshire"}
