Abstract: Clay Minerals of West Texas Ogallala Group

R. W. Lee, J. Goolsby

Thirty samples Previous HitfromNext Hit three stratigraphic sections of the Ogallala Group were taken along the eastern escarpment in Crosby, Floyd, and Garza Counties, Texas. X-ray Previous HitdiffractionTop revealed that sepiolite was present only in the top part of the "Caprock" caliche with attapulgite and smectite being the major clay minerals throughout most of the Ogallala sections with small amounts of illite and kaolinite. The predominance of attapulgite and smectite and the presence of the uppermost sepiolite zone are similar to the clay mineralogy of the Ogallala Group in eastern New Mexico and thus provide valuable paleoclimatic clues.
