Geologic Map of The Faust Quadrangle, Tooele County, Utah

By: Stefan M. Kirby

This map represents the geology of the Faust quadrangle at 1:24,000 scale. The Faust quadrangle covers part of Rush Valley and includes the southeastern part of the Onaqui Mountains, the northernmost Vernon Hills and adjoining parts of the valley floor in southeastern Tooele County, Utah. Most of the Faust quadrangle is covered by unconsolidated deposits of Holocene to Pleistocene age. These deposits include various alluvial fan and channel deposits, and lacustrine units deposited during the maximum transgression of Lake Bonneville. At least two prominent systems of normal faults along the flank of the Onaqui Mountains and near the Vernon Hills cut unconsolidated deposits within the quadrangle. Sedimentary rocks exposed in the quadrangle include folded Pennsylvanian bedrock of the Oquirrh Group consolidated Tertiary basin fill of the Salt Lake Formation.
