ASU Geology Group to Show Research at National Meeting

The collaborative research of several current and former Angelo State University faculty and students on the structural geology and tectonics of Big Bend National Park will be presented at the 119th annual meeting of the Geological Society of America (GSA) Oct. 27-31 in Denver, Colo.

The research, part of a symposium titled “Geological, Geophysical, Geochemical and Environmental Studies in Big Bend National Park and the Trans-Pecos Region,” was conducted by Dr. Joe Satterfield, assistant professor of geology; Dr. Christian Poppeliers, a former ASU physics professor now at Augusta State University; 2007 ASU graduate Jonathan Dyess; junior biology major Andrew Garcia; and part-time ASU geology student Ryan Sonntag.

Satterfield and co-authors Dyess, Sonntag and Poppeliers will attend the meeting and make a poster presentation of their research, titled “Polyphase Folds and Faults Within a Wrench Fault Zone, Northern Big Bend National Park, Texas.” The poster displays detailed mapping of rock types, faults and folds in a portion of Sierra del Carmen within the national park.
