Low δ18O rhyolites and crustal melting: Growth and redistribution of the continental crust

Twin Falls, Idaho, and Yellowstone National Park, Wyoming, USA
9–13 September 2009

Washington State University, School of Earth and Environmental Sciences, Pullman, Washington 99164-2812, USA,

In the past several years, there has been a renewed interest in the genesis of low-δ18O rhyolites and shallow magma genesis. This resurgence has been stimulated by a combination of the application of new analytical techniques and the discovery of voluminous low-δ18O rhyolites in the Snake River Plain, Idaho, USA. Low-δ18O rhyolites are important because oxygen is the most abundant element in igneous rocks, and it provides fundamental evidence about crustal processes that form rhyolite magmas.

The meeting will include keynote presentations by HP Taylor, K. Muehlenbachs, C. Harris, and G. Bergantz.
