Geoscience from the Archean to the Anthropocene converges in Minneapolis

Registration is open for the Geological Society of America’s (GSA’s) 123rd Annual Meeting and Exhibition, to be held 9-12 October 2011 at the Minneapolis Convention Center in Minneapolis, Minnesota, USA. Minneapolis has not hosted the GSA meeting since 1972, and the 2011 Midwest meeting is shaping up to be one of GSA’s largest!

“This year’s theme, Archean to Anthropocene, the past is the key to the future, captures the broad research and education agenda of the GSA community as a whole, as well as the application of our work to society,” says Harvey Thorleifson, Minnesota State Geologist and GSA’s Local Planning Committee Chair. “Recent escalation of the visibility of the Anthropocene concept illustrates the scientific relevance of the meeting, and our program will provide an opportunity for participants to make contact with and reflect on current influential thinking on this topic.”

Representatives of the media are cordially invited to attend and participate in technical sessions, field trips, and other special events. Eligible media personnel receive complimentary registration and are invited to use GSA’s Newsroom facilities while covering the meeting.

Field Trips

Early October is prime field season in the upper Midwest. A diverse slate of 45 field trips span a geologically broad range of topics, including the Precambrian geology of the southern Canadian Shield; the economic geology of the Lake Superior region; Phanerozoic strata in Minnesota, Wisconsin, Iowa, and North Dakota; glacial geology; hydrogeology and limnology; undergraduate and K󈝸 geoscience field education; the geology and hydrology of the Twin Cities metro area; geology by bicycle; terroir; geoarchaeology; biogeohydrochemistry; and tours of area research labs and vessels.
