GSA Cordilleran Section field trip

Dear VolcanoPhiles,
Following the Geological Society of America’s Cordilleran Section meeting, to be held in Querétaro, Mexico, from 29 – 31 March, 2012, Gerardo Carrasco-Nuñez and colleagues will lead Trip 8, Recent Volcanism and Hazards in the Eastern Trans-Mexican Volcanic Belt, from 31 March – 2 April. The cost is US$320, and the trip will start and end in Querétaro.
In this field trip we will examine examples of recent (late Pleistocene and Holocene) volcanism in the eastern Trans-Mexican Volcanic Belt, where a diversity of volcanism and spectacular exposures can be seen. We will explore the complex pyroclastic succession and caldera-rim effusions of Los Humeros caldera volcano and geothermal field. We will also examine a very interesting vitrophyric rhyolite dome (Cerro Pizarro) and the structure and evolution of two contrasting maar volcanoes: Atexcac (a classic basaltic maar) and Cerro Pinto, a rhyolitic tuff ring-dome complex.
For more information please contact any of us, or go to http://www.geosociety.org/Sections/cord/2012mtg/index.htm for information about the meeting and registration.
