The database presented here represents the first of those objectives, and it includes more data that was gathered after the third objective was accomplished. It was originally compiled in close cooperation with exploration and mining companies operating in Missouri, who provided drillhole data, core and rock samples to MGS. These data enabled geologists to study otherwise unexposed basement rocks from a large area of the state for the first time, allowing better classification and understanding of the Precambrian basement across the state. MGS is continuing data collection and database compilation today as information becomes available, furthering our knowledge of the Missouri Precambrian basement. This effort was supported through a cooperative agreement with the Mineral Resource Program of the U.S. Geological Survey.  There is no plan to update this Data Release product.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7959GGM", "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.59b16c3fe4b020cdf7d90904.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_59b16c3fe4b020cdf7d90904", "keyword": ["Polk County", "drill core", "Atchison County", "Franklin County", "Brown Mountain", "Moniteau County", "Hickory County", "volcanic", "St. Louis County", "Benton County", "Cedar County", "Holt County", "Oregon County", "Precambrian", "Madison County", "Gentry County", "Barry County", "Gasconade County", "Platte County", "Cardareva Mountain", "Phelps County", "McCracken Core Library and Research Center", "igneous rock", "McDonald County", "plutonic", "Bozarth State Forest", "Coldwater State Forest", "Morgan County", "Mark Twain National Forest", "Jasper County", "Missouri Geological Survey", "Nodaway County", "Vernon County", "Carter County", "Ozark National Scenic Riverways", "trachyte", "Texas County", "Adair County", "Taney County", "Crawford County", "Johnson County", "drill cuttings", "USA", "Pulaski County", "St. Clair County", "biotite", "Audrain County", "Rockpile Mountain", "Dade County", "Cold Water Hills", "Flint Hill", "Mesoproterozoic", "Wayne County", "Washington County", "Iron County", "Cass County", "Deer Run State Forest", "rhyolite", "Jefferson County", "Laclede County", "United States of America", "Lafayette County", "Reynolds County", "St. Francois County", "Pettis County", "Ralls County", "Saline County", "Bell Mountain", "porphyry", "Dallas County", "granite", "Ste.
