Warren Hobbs for his research on the Coeur d'alene Mining District, Idaho - Professional Paper 478 (1965).\nThe Coeur d'Alene Study:\nGeneral geology of the Coeur d'Alene district, one of the larger lead-, zinc-, and silver-producing areas of the world, is presented. The geology was remapped at a scale of 1:24,000 and compiled on five maps from west to east as follows: Smelterville, Kellogg, Wallace, Mullan, and Pottsville. Bedrock, primarily the Precambrian Belt Series which forms the host rock for the ore, is a thick conformable geosynclinal group of fine-grained clastics. Igneous rocks are principally two groups of small monzonitic intrusives and other dikes. Structurally the district is located at the intersection of a major anticlinal arch in the geosynclinal sediments with a major zone of weakness, the Lewis and Clark line; faults are the dominant structural feature. Mineral deposits formed near satellite intrusions of larger igneous bodies intruded during the Mesozoic within a structural knot of highly fractured rocks.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9XD3CQO", "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.732d7e06-0859-464f-b417-0875b01d37c7.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_732d7e06-0859-464f-b417-0875b01d37c7", "keyword": ["Geology", "Idaho", "USGS:732d7e06-0859-464f-b417-0875b01d37c7", "critical resources", "geological maps", "mining"], "modified": "2023-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-117.243027, 41.988057, -111.043564, 49.001146", "theme": ["geospatial"], "title": "USGS S.
