E-6*: Structure of Ogallala Formation in east-central New Mexico
by J. C. Frye and A. B. Leonard, 1972, 8 p.
(*The first 7 publications in this series were designated "target exploration" reports)
Preliminary plotting of the elevation of the top of the Ogallala Formation (late Miocene and Pliocene) permits the construction of structure contours on this surface. The contours have been projected across the extensive areas from which the Ogallala has been removed by Pleistocene erosion; also across the many areas of Pleistocene subsidence. The contours have not been corrected for the initial depositional slope of the Ogallala deposits toward the southeast or the minor initial irregularities; nevertheless the contours indicate some structural warping during the Pleistocene.
