Title: Proposed Surface Reference Section for Yates Formation, Eddy County, New Mexico: GEOLOGICAL NOTES

Author(s): Starr Lanphere (2)

Abstract:

The Yates Formation of Guadalupian (Permian) age, named for the Yates oil field, Pecos County, Texas, is a subsurface clastic unit. It extends over the Central Basin platform and onto the Northwestern shelf of New Mexico, within the interval between the Seven Rivers and Tansill Formations of the Artesia Group. Subsurface type sections have been designated for both Texas and New Mexico. This paper proposes that an outcrop of the Yates Formation in lower Dark Canyon (Secs. 26, 27, T23S, R25E), Eddy County, New Mexico, be adopted as the surface reference section.

The Yates of this locality is well exposed as an intermittent cliff- and slope-forming unit between the cliff-forming Tansill and Seven Rivers Formations. The section totals 313 ft of interbedded siltstone, sandstone, and carbonate rocks. The upper contact is the top of a well-defined buff to ocher calcareous siltstone from 3 to 5 ft thick. The lower contact is not clearly defined, but is the base of the first buff sandy calcareous unit above the predominantly gray limestone of the Seven Rivers.
