SALT LAKE CITY, Oct. 18, 2005 – Several New Mexico Tech geoscientists are in Salt Lake City, Utah, presenting talks and posters about their current research at the 117th annual meeting of the Geological Society of America (GSA), which is being held October 16-19 at the Salt Palace Convention Center.

Approximately 6,200 geoscientists from throughout the world are expected to attend this year’s conference. In all, 42 New Mexico Tech professors, researchers, and graduate students will give 31 scientific presentations at the annual convention.
