SOCORRO, N.M., May 7, 2002 -- Two New Mexico Tech geoscientists present talks at the 54th annual meeting of the Rocky Mountain Section of the Geological Society of America, held in Cedar City, Utah.

Shari Kelley, an adjunct professor of geology at New Mexico Tech, and Tech graduate student Scott Lynch gave presentations on their current research studies at the annual convention of more than 400 geoscientists.

Kelly's presentation, "Cretaceous Shales and Their Influence on Denudation Estimates for the Southwestern United States," uses reconstructions of stratigraphic sections in the Grand Canyon, Colorado's Front Range, and the northern section of New Mexico's Rio Grande rift to illustrate the influence of lithology on the geometry of paleo-isotherms.

Lynch's presentation, "Geology of the Central San Mateo Mountains, New Mexico," determines rock distribution and stratigraphy, makes correlations with rocks mapped elsewhere in the Mogollon-Datil volcanic field, and establishes the timing of eruptive events in southwestern New Mexico's San Mateo Mountains.
