Digital database for the geologic map of the Vidal, California, and Parker SW, California-Arizona quadrangles

Metadata Updated: October 28, 2023

This geologic database is a digitized version of the original 1:24,000-scale analog geologic map titled "Geologic map of the Vidal, California, and Parker SW, California-Arizona quadrangles", published by the U.S. Geological Survey (USGS) in 1980. The map area straddles the Arizona-California border, and is located approximately 9.0 km (5.6 mi) west-southwest of Parker, CA, immediately south of the unincorporated communities of Vidal and Vidal Junction, CA. The map area includes the northern Riverside Mountains, which contain a prominent suite of Permian, Mesozoic, and potentially Precambrian metamorphic and metasedimentary rocks. These rocks predominantly consist of gneisses, schists, limestones, and dolomites, separated by three mapped structural discontinuities and the prominent Whipple Mountains Detachment Fault. The map area additionally contains small outcrops of Miocene intermediate-to-felsic volcanic rocks consisting of basaltic andesite flows, andesitic porphyry, rhyolitic intrusives, and the Peach Springs Tuff. The Riverside Mountains are surrounded by numerous sedimentary units, largely consisting of fluvial deposits, that record the arrival and subsequent fluctuations of the Colorado River in the region from the Pliocene through the Holocene. These sedimentary units additionally record Quaternary alluvial fan processes on the flanks of the Riverside Mountains and in the lower Vidal Valley.
