Map 77

The Tecoma quadrangle is located in northwestern Utah along the Nevada-Utah border about 65 km south of the Idaho-Utah border. Part of the northern end of the Pilot Range is exposed within this quadrangle. The Pilot Range is a north-trending, fault-bounded mountain range typical of the ranges in the northern Basin and Range Province. In this range, sedimentary rocks typical of the Cordilleran miogeocline were deposited during Late Proterozoic and Paleozoic time. The area was the site of igneous intrusion, metamorphism, folding, and low-angle faulting during Mesozoic time. Cenozoic high-and low-angle faulting, igneous activity, and local metamorphism modified the Mesozoic structures, commonly making their recognition difficult.
