DENVER, Nov. 2, 2004 -- Several New Mexico Tech geoscientists presented talks and posters about their research at the 116th annual meeting of the Geological Society of America (GSA), which was held November 7-10 at the Colorado Convention Center.

Approximately 6,200 geoscientists from throughout the world attended this year's conference. In all, 25 New Mexico Tech professors, researchers, and graduate students will give 28 scientific presentations at the annual convention.
