Digital Data for the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona

February 16, 2022

This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona, U.S. Geological Survey Open-File Report 2021-1097. The Blythe 30' x 60' quadrangle in southeastern California and southwestern Arizona displays complex geology that includes Mesozoic contractional deformation, metamorphism, and magmatism and Cenozoic extensional deformation and magmatism. The scope of the present map is limited to bedrock units of Miocene and older age because the younger deposits have not been mapped in sufficient detail across the quadrangle to support a systematic compilation. This geologic map database is accompanied by a report, which includes the formatted geologic map and explanatory pamphlet, available at https://doi.org/10.3133/ofr20211097. The authors ask that users of the geologic map database cite both the report and the database: Report: Stone, P., Spencer, J.E., and Beard, L.S., comps., 2022, Preliminary bedrock geologic map of the Blythe 30' x 60' quadrangle, California and Arizona: U.S. Geological Survey Open-File Report 2021-1097, 1 sheet, scale 1:100,000, 10-p. pamphlet, https://doi.org/10.3133/ofr20211097.
