The 29 lithogeochemical units can be\nsummarized into 6 major categories: \n(1) carbonate-rich rocks,\n(2) carbonate-poor, clastic sedimentary rocks restricted to distinct\ndepositional basins, \n(3) metamorphosed, clastic sedimentary rocks\n(primarily noncalcareous), \n(4) mafic igneous rocks and their metamorphic\nequivalents, \n(5) ultramafic rocks, and \n(6) felsic igneous and plutonic rocks and their metamorphic equivalents.  \nLithogeochemical rock units also are grouped into nine lithologic and \nphysiographic provinces (lithophysiographic domains), which can be \nsummarized into three major\nregions: \n(1) western highlands and lowlands, \n(2) central lowlands, and\n(3) eastern highlands.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9VU4WUV", "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.b0104dce-c0e5-4722-8d24-852fea8b0ff2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_b0104dce-c0e5-4722-8d24-852fea8b0ff2", "keyword": ["1:125", "Connecticut River", "NAWQA", "USGS:b0104dce-c0e5-4722-8d24-852fea8b0ff2", "bedrock", "environment", "geoscientificInformation", "inlandWaters", "lithogeochemical"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-73.84628191, 40.93919878, -71.07271366, 45.30085759", "theme": ["geospatial"], "title": "Lithogeochemical Character of Near-Surface Bedrock in the Connecticut, Housatonic and Thames River Basins"}
