SOCORRO, N.M., May 2, 2003 - David W. Love, Nelia Dunbar, and William C. McIntosh, geologists at the New Mexico Bureau of Geology and Mineral Resources (NMBGMR), in cooperation with Isleta Pueblo geologists and New Mexico Tech alumni John Sorrell and David Pierce, will present their geoscience research at the 55th Annual Meeting of the Rocky Mountain Section of the Geological Society of America (GSA). The meeting, hosted by the Department of Geosciences at Fort Lewis College in Durango, Colorado, will be held May 7 to 9, with 250 geoscientists in attendance.
The presentation to be given by the New Mexico Tech geologists, titled "Volcanic debris from the Jemez Mountains constrain the age, sediment-source history, and deformation of fluvial facies of the ancestral Rio Grande (upper Santa Fe Group), central Albuquerque Basin, New Mexico," details the stratigraphy of the Rio Grande basin.
The talk will focus on the variety and ages of volcanic materials from the Jemez Mountains, including ash, obsidian, pumice, and rhyolitic tuff, that were transported by the Rio Grande and deposited throughout the Albuquerque Basin.
