The Yates Formation is a geologic formation in southeast New Mexico and west Texas. It preserves fossils dating back to the late Guadalupian Age of the Permian period.Gester and Hawley 1927Tait et al. 1962
Description
File:Yates Fm Walnut Canyon.jpg
The formation consists of sandstone, siltstone, and anhydrite. The sandstone is fine to very fine grained and contains scattered large rounded and frosted quartz grains. The formation overlies the Seven Rivers Formation and underlies the Tansill Formation. Its total thickness is {{convert|266|feet|meters}}.
History of investigation
The unit was first identified in the subsurface at the Yates oil field of west Texas. It was first traced to surface outcrops in the Carlsbad, New Mexico area in 1938 and assigned as a member of the (now abandoned) Whitehorse Formation.DeFord et al. 1938 Dickey raised the unit to formation rank in 1940, when the Whitehorse was raised to group rank.Dickey 1940 The unit was reassigned to the Artesia Group in 1962.
