Geological Survey Bulletin 1244-J Carmel Formation of The Zion Park Region Southwestern Utah - A Review

By W. B. CASHION

The name Carmel Formation was first applied to rocks of Jurassic age in the San Rafael Swell of east-central Utah, although the type locality is in the Zion Park region of southwestern Utah. Subsequently, the Carmel Formation of the Zion Park region was modified as the use of other established names was extended and new names, such as the Winsor Formation, were introduced. As presently defined, the Carmel Formation of the Zion Park region includes all Jurassic strata above the Navajo Sandstone. Because this sequence contains beds previously assigned to the Winsor Formation, the Winsor is reduced in rank to a member of the Carmel Formation.
