Geologic Map of the Cerbat 7.5' Quadrangle, Mohave County, Arizona, v. 1.1

The study area includes the southern Cerbat Mountains and a portion of northern Sacramento Valley in Mohave County, northwest Arizona (Fig. 1). Elevations vary across the study area, with elevations in Sacremento Valley ranging from 2900’ in the southwest to 3800’ in the northeast, and the Cerbat Mountains start at 3600’ to 3800’ along the western margin, with major peaks ranging from 5100’ to 6230’. The area lies within the Mohave Desert with large areas of relatively open desert in Sacramento Valley punctuated by thick brush zones along major washes. Bedrock geology was mapped by Carson Richardson during the spring of 2020, and the surficial geology was mapped by Philip Pearthree in the spring of 2020. Some areas within the vicinity of the Mineral Park mine and patented mining claims were mapped using remote techniques and compilation of previous published mapping and reports. This publication includes a geologic map, report, and set of supplementary digital files that describe the geology of the southern Cerbat Mountains and a portion of northern Sacramento Valley in Mohave County, northwest Arizona. It was initially published in 2022 with funding from the Arizona Geological Survey and from the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G19AC00381. It was later lightly revised in 2025 under STATEMAP award number G23AC00556 (present version, v. 1.1). The 2025 revisions only included changes to the database schema and GIS files. No substantive changes were made to the geologic interpretations or data.
