Geologic map of the Chriss Canyon quadrangle, Juab and Sanpete Counties, Utah (M-185)

By: M. P. Weiss, J. G. McDermott, D. A. Sprinkel, R. L. Banks, and R. F. Biek

The Chriss Canyon quadrangle lies in a region of structural transition between the extended lithosphere of the Basin and Range Province and the moderately deformed Colorado Plateau. In Late Cretaceous time this region was the leading edge of the Sevier orogenic belt. Bedrock strata exposed within the quadrangle are from Middle Jurassic (Callovian) through late Eocene in age. Minor intrusive rocks are Miocene in age. A transect across this quadrangle and the Wales quadrangle just to the east shows the sedimentary and structural record of the region prior to and during the Sevier orogeny, the effects of early and late Laramide movements, and the consequences ? still preserved as geomorphic features ? of subsequent Basin and Range extension.
