Getting closer to Granite Peak of the Mineral Mountains. https://geology.utah.gov/map-pub/survey ... -mountain/
The preliminary results of our research have given us insight into the geologic context of Granite Peak Mountain. This mountain is one of several intrusions in western Utah, Nevada, and the Sierra Nevada mountains of California emplaced in Late Jurassic time. This regional mountain-building event may be attributed to the Nevadan orogeny from about 160 to 120 million years ago (Late Jurassic to Early Cretaceous), a precursor to the Sevier orogeny which significantly affected the western half of Utah from about 120 to 40 million years ago (Early Cretaceous to Eocene).
The Jurassic igneous and metamorphic rocks were subsequently exposed through doming and/or extensional faulting. The extension or stretching of western Utah and the Great Basin began about 17 million years ago and continues today.
