This is the final 2 weeks before abstracts submission are do and therefore a final reminder to submit an abstract to our session T165 Recent advances in understanding volcanism of the Yellowstone hotspot at the upcoming GSA annual meeting in Seattle, Washington, Oct. 22-25, 2017.
A.R. Steiner, J.A. Wolff, and M.J. Streck
T165. Recent advances in understanding volcanism of the Yellowstone hotspot
Invited speakers for this session include
Vic Camp
Jorge Vazquez
Ilya Bindeman
Volcanic activity within the inland northwest United States during the mid-Miocene is largely a response to the Yellowstone hotspot. Mid-Miocene age volcanic rocks of the Columbia and Eastern Oregon Plateau and the Snake River Plain, including northern Nevada, are all products of this activity. Contributions to this session will centralize on: 1) the timing and extent of the Yellowstone hotspot; 2) timescales of magma formation; 3) how Oligocene age volcanic units such as John Day and Clarno formations might be related to the Yellowstone hotspot (e.g. possible precursor eruptions?); 4) magma dynamics, including rejuvenation within a single volcanic cycle (e.g. magma mixing) and crustal melts; and 5) what the silicic products (including andesite and rhyolite) can tell us about crustal modification associated with hotspot volcanism. Submissions from various disciplines surrounding the topics covered above are encouraged, including volcanology, petrology, geochemistry, geophysics and numerical/computational modeling.
Thanks,
Arron Steiner
