Petrogenesis of pyrite-bearing assemblages in the Thomas Range of Western Utah
The Thomas Range is part of the Basin and Range and is just west of the Wasatch hinge line. As a part of the Cordilleran Miogeocline, sediments were deposited in the Thomas Range area. The Thomas Range also underwent a wave of volcanism after the ocean regressed. Elemental and mineral analyses were performed on pyrite-bearing assemblages found in the Thomas Range of Western Utah. Petrogenesis of the sample is determined using the known minerals and the ways those minerals form. Pyrite associated with a sedimentary rock confirms that there was an anoxic sea covering the Thomas Range at some point in geologic history.
