... other localities in Utah. In 1934 Thomas (p. 1666) applied the name Ervay to a limestone 16 feet thick at the top of the Permian sequence of interbedded red shale and carbonate rock in the Rattlesnake Hills, Wyoming. He considered it a tongue of the Phosphoria formation because of its lithologic...

..., but for purposes of discussion, the rocks above a 10-foot chert bed are referred to as the “E” zone. The “E” zone is roughly equivalent to the Ervay tongue as used by McCue (1953). The relationship of the Ervay tongue to the rest of the Phosphoria and to the eastward facies change is shown in Figure 4 . Fig...

If exposures were better and the structural relations were clearer at the various localities, the Plympton Formation probably could be subdivided into members or tongues much like the Phosphoria Formation. The Plympton rocks are structurally more ductile than the underlying...
