The area encompasses 23,000 square miles in western\nand central Maine, eastern Massachusetts, most of Rhode Island,\neastern New Hampshire and a small part of eastern Connecticut.\nThe NECB study area includes the Kennebec, Androscogginn, Saco,\nMerrimack, Charles, and Blackstone River Basins, as well as all\nof Cape Cod. Bedrock units in the NECB study area are classified into\n38 lithogeochemical units based on the relative reactivity of their\nconstituent minerals to dissolution and the presence of carbonate or\nsulfide minerals. The 38 lithogeochemical units are generalized into 7\nmajor groups: (1) carbonate-bearing metasedimentary rocks; (2)primarily\nnoncalcareous, clastic sedimentary rocks with restricted deposition in\ndiscrete fault-bounded sedimentary basins of Mississipian or younger age;\n(3) primarily noncalcareous, clastic sedimentary rocks at or above\nbiotite-grade of regional metamorphism; (4) mafic igneous rocks and\ntheir metamorphic equivalents; (5) ultramafic rocks; (6) felsic igneous\nrocks and their metamorphic equivalents; and (7) unconsolidated and poorly\nconsolidated sediments.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9G0VSQZ", "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.148f11d8-5149-417f-a29d-663d2294206c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_148f11d8-5149-417f-a29d-663d2294206c", "keyword": ["Androscogginn River Basin", "Bedrock", "CONN", "CONN NAWQA study unit", "Charles River Basin", "Connecticut", "Geochemical", "Geology", "Kennebec River Basin", "Lithogeochemical", "Lithology", "Maine", "Massachusetts", "Merrimack River Basin", "Mineral", "NAWQA", "NECB", "NECB NAWQA study unit", "New Hampshire", "Pawcatuck River Basin", "Rhode Island", "Saco River Basin", "Taunton River Basin", "USGS:148f11d8-5149-417f-a29d-663d2294206c", "Water chemistry", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-72.19068043, 41.13443365, -69.03158607, 45.90221224", "theme": ["geospatial"], "title": "Lithogeochemical Character of Near-Surface Bedrock in the New England Coastal Basins"}
