Interim Geologic Map of the Kanarraville Quadrangle, Iron County, Utah (OFR-618)

By: Robert F. Biek and Janice M. Hayden

The Kanarraville quadrangle includes the southern part of Cedar Valley and parts of the adjacent Kolob Terrace, Harmony Mountains, and North Hills. It straddles a particularly instructive area of structural overlap between the Sevier fold thrust belt-represented by the overturned, east limb of the Kanarra anticline exposed at the west edge of the Kolob Terrace-and the Basin and Range physiographic province, whose east margin corresponds to the Hurricane fault zone at the base of the plateau. Regional ash-flow tuffs erupted from calderas in western Utah and eastern Nevada are present in the Harmony Mountains and North Hills; in the Harmony Mountains, these tuffs are involved in a large gravity slide shed off the nearby Stoddard Mountain laccolith, which erupted to produce an ash-flow tuff now partly buried by the gravity slide.
