Local Geology, Global Connections: GSA Cordilleran Section to Convene in Fresno


Boulder, CO, USA – Geoscientists from western North America and beyond will convene in Fresno, California, USA, on 20–22 May to celebrate GSA's 125th Anniversary and discuss current geoscience research. This meeting emphasizes the international relevance of Cordilleran geology, with a higher than usual number of non-American presenters for a regional meeting. Topics include tectonic and petrologic processes associated with active plate margins, salmon spawning sites restoration, new regulations for fault rupture hazard zones, and water supply issues.

Fresno is ideally located for exploring the best of Cordilleran geology—nestled at the foot of the Sierra Nevada, and yet still within a short driving time of the geologic wonders of the California Coast Ranges. The field trips for this meeting fully exploit these advantages, including explorations along Panoche Pass to the San Francisco Bay Area, visits to the Fairmead Landfill Fossil Site and Fossil Discovery Center, and the western Sierra Nevada foothills between the San Joaquin and Kern Rivers.

The meeting will take place at the Radisson Hotel and Conference Center in Fresno.

Local Committee and Technical Program Chair John Wakabayashi of California State University–Fresno says that many of the technical sessions, highlighted below, reflect "big-picture science that also highlight the international character of this meeting," noting that "several of the critical zone sessions bear on very large-scale processes of interest to many globally." Wakabayashi adds, "Four related sessions on tectonic and petrologic processes at convergent plate margins are by far the most international of the meeting."

Science presentations cover local geology as well, including papers on the paleoecology of western North America (Monday, 1:30 to 5:30 p.m., and poster session on Tuesday); the Pacific-North America plate boundary (Tuesday, 8 a.m. to noon, with a poster session on Monday); and oceanic petrogenesis of Pacific-type convergent margins (Wednesday poster session).

SELECTED HIGHLIGHTS FROM THE SCIENTIFIC PROGRAM

The scientific program is composed of oral and poster presentations organized into 16 themed sessions plus an array of research in general discipline areas. Go to http://www.geosociety.org/sections/cord/2013mtg/techprog.htm to learn more.
