Drill core data for the Courtland-Gleeson area, Turquoise mining district and southern Dragoon Mountains, Cochise County, Arizona

The Arizona Geological Survey (AZGS) is determined to provide digital access to geological data whenever possible. As part of these efforts, archival data associated with drill core from the Courtland-Gleeson area has been scanned and tabulated as part of this data set. This data set comprises drill logs, assays, company reports and maps, core photos, geophysical studies, and correspondence. The tabulated drill data represents 25,935 m (85,087 feet or 16.1 miles) of drilling for lithology, alteration, mineralization, structure, and assays across 113 drill holes. Two geologic maps originally made by exploration geologists were digitized to provide context for the drill holes. The tabulated data is available as a set of spreadsheets, and also available as an interactive webmap, where direct links are provided to the original files from which this data set was generated.Documents in the AZGS Documents Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.
