The geochemical data are also used in assessments of oil and gas potential for sedimentary basins in both national and international settings (USGS Geochemistry Database, 2024).  The EGDB is a compilation of organic and inorganic analytical data from the ERP Laboratory Information Management System (LIMS), historic databases, and data compiled from literature and unpublished public domain sources.\nThe EGDB is a relational database comprised of a \u201cSamples\u201d table, \u201cAnalysis\u201d table, \u201cOrdersComments\u201d table and several data dictionary tables. The \u201cSamples\u201d table contains information pertaining to the location where the samples were collected and geologic information about the samples. The \u201cAnalysis\u201d table contains records of analysis results from the analyses performed on the samples. The \u201cOrdersComments\u201d table contains additional information about the samples for each order ID.  The data dictionary tables are named accordingly, followed by type of data in each table.  Several predefined queries are included to assist with extracting data. The queries can be modified to fit user defined criteria.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1WNUHWO", "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.68a8a28fd4be026335793f26.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68a8a28fd4be026335793f26", "keyword": ["Afghanistan", "Arctic Ocean", "Argentina", "Armenia", "Australia", "Austria", "Azerbaijan", "Bangladesh", "Barbados", "Belarus", "Belgium", "Belize", "Bolivia", "Brazil", "Bulgaria", "CERSC", "Cameroon", "Canada", "Chile", "China", "Colombia", "Costa Rica", "Croatia", "Cuba", "Czech Republic", "EGDB", "Energy Geochemistry Database", "Estonia", "Ethiopia", "France", "Gabon", "Germany", "Greece", "Hungary", "India", "Indonesia", "Iran", "Iraq", "Ireland", "Israel", "Italy", "Japan", "Jordan", "Malaysia", "Mauritania", "Mexico", "Mongolia", "New Zealand", "Nigeria", "None", "Pakistan", "Peru", "Poland", "Portugal", "Puerto Rico", "Republic of Ireland", "Russia", "Rwanda", "Saudi Arabia", "Scotland", "Serbia", "Slovakia", "South Korea", "Spain", "St. Lucia", "Sweden", "Switzerland", "Tajikistan", "Tanzania", "Thailand", "Trinidad and Tobago", "Turkey", "U.S. Geological Survey", "USGS", "USGS Central Energy Resources Science Center", "USGS Energy Resources Science Center", "USGS:68a8a28fd4be026335793f26", "Ukraine", "United Kingdom", "United States", "Venezuela", "Yugoslavia", "Zimbabwe", "analytical chemistry", "biota", "energy resources", "geochemistry", "geochemistry data"], "modified": "2026-09-02T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-179.1833, -52.9554, 179.3300, 88.9405", "theme": ["geospatial"], "title": "Energy Geochemistry Database (ver. 2.0, September 2026)"}
