Circular 104 — Border Stratigraphy Symposium

Edited By: Frank E. Kottlowski, and David V. Lemone, 1969, A. R. Sanford and D. J. Cash, 1969, 123 pp.

This Border Stratigraphy Symposium was held at the University of Texas in El Paso, April 30, 1968, as part of the Forty-Fourth Annual Meeting of the Southwestern and Rocky Mountain Division of the American Association for the Advancement of Science. Interest in the data presented, particularly by geologists unable to attend the symposium technical session, led to requests for publication of the papers.

Some of the material has been published in abstracts and in part in other journals, particularly McGlasson's, LeMone's, and Kottlowski's data. Compilation of descriptions of most of the rock units in the El Paso border region in a single volume should aid future geologic work in this area. Descriptions of the Cenozoic strata, the surface and near-surface rocks on which the cities of the border region are built, should be of much aid in the urban development of El Paso, Las Cruces, and Juarez.
