Layer contains location and details of known uranium occurrences, uranium prospects, and radioactive anomalies. Data was compiled from WSGS internal notes. It is symbolized by type and includes attributes such as host formation, deposit type, details of the occurrence, and the original reference. For the purpose of this dataset, a uranium occurrence is defined as a concentration in which the amount of the element, as determined by either radiometric or chemical analysis, is greater than 50 parts per million (0.005 percent). Equivalent uranium (eU) concentration is determined by measuring the radioactivity of a sample. Chemical uranium (cU) concentration is determined by quantitative chemical analysis. Alternatively, an occurrence (or anomaly) is also defined as a locality with ten times or more radioactivity than the normal background radiation. This definition of occurrence is the same as used in previous WSGS publications RMR 97-01, RMR 97-02, RMR 95-1, OFR 93-1, OFR 93-2, OFR 93-3, OFR 93-4.

This data release contains the digital data for the Wyoming uranium resources database. The data were created to provide a comprehensive collection of scientific and historic information about the geology of uranium deposits and the uranium industry in Wyoming in a geospatial format. The geodatabase includes the following layers: ConventionalMines, InSituRecoverySites, Mills, Occurrences, MiningDistricts, SpatialBibliography, and References.

OccurrenceType
Categorical description of the occurrence at each feature. Five categories used: "Unverified Occurrence", "Radioactive Anomaly", "Radiometric Analysis", "Chemical Analysis", "Prospect". An occurrence is considered an "Unverified Occurrence" if WSGS internal notes labeled the point as unverified, OR if the analysis type is unknown, OR if there was only a mineral identification given. An occurrence is considered a "Radioactive Anomaly" if the only information reported was the radioactivity reading relative to background radioactivity. An occurrence is considered a "Radiometric Analysis" if radiometric methods were used to measure uranium concentration. An occurrence is considered a "Chemical Analysis" if chemical methods were used to measure uranium concentration. An occurrence is a "Prospect" if some development occurred, but no production and it is not currently permitted or licensed.
