This report is preliminary and has not been edited or reviewed for conformity with Arizona Geological Survey standards

In 1992 the Arizona Geological Survey (AZGS) organized a repository in which drill core that the AZGS has accumulated through donations is stored and available for public inspection. The repository is presently located in the basement of the Corbett Building (210 E. 7th Street) in Tucson, Arizona. Core samples in the facility represent almost 300 individual drill holes and approximately 150,000 linear feet of hole. All the core has been skeletonized (either by the donor or by AZGS geologists) to varying degrees, with from 20% to less than 1 % of the original core retained. Fourteen of Arizona's fifteen counties are represented in the storage facility by at least one drill hole, with Apache, Cochise, Maricopa, and Mohave Counties represented by the most individual holes. The core was produced during various projects ranging from geotechnical site assessments to metallic mineral exploration.

Only the core drilled and donated by the U.S. Bureau of Mines (BOM) and Bendix Field Engineering Corp. is described in published reports, which are listed below. AZGS files contain unpublished reports and drill logs for some of the core, but much is without any documentation other than this report. An OGCe (Oil and Gas Conservation Commission) file number is listed as a source of information for some core (OGCC files are kept at the AZGS). A complete inventory of the contents of the AZGS core repository is tabulated below. Available location diagrams have been reproduced from original sources and appended to the end of the inventory table. Anyone wishing to inspect any of the core should contact the Arizona Geological Survey by telephone at (602) 882-4795 or by mail at 845 N. Park Ave., #100, Tucson, AZ 85719.
