Beaver Dam Mountains-Tule Springs Hills-Mormon Mountains Thermochronology - 2015-01-22

This dataset contains apatite and zircon (U-Th)/He data from the Beaver Dam Mountains, Tule Springs Hills, and Mormon Mountains of southwestern Utah and southeastern Nevada. The region is host to three major low-angle structures, the Castle Cliffs, Tule Springs, and Mormon Peak detachments, whose origin and role in regional extension are vigorously debated. We analyzed 36 samples collected from Precambrian basement gneisses and Paleozoic to Jurassic siltstones and sandstones exposed in the footwalls of these detachments. Samples from the Beaver Dam and Mormon mountains were collected earlier by Stockli (1999); samples from the Tule Springs Hills were collected during the course of this study.
