DESCRIPTION:Dr. Maddie Lewis\nU Wyoming\n\nTopic: Tying caldera-forming eru
 ptions to their magma storage regions: timing\, magma compositions\, and s
 torage conditions\n\nAcademic Host: Kevin Mahan\n\nAbstract: Caldera-formi
 ng eruptions are among the largest and most disruptive volcanic events in 
 Earth history. Throughout the mid-Cenozoic\, the Great Basin experienced a
 n extensive period of explosive silicic volcanism\, which produced massive
  ash-flow tuff deposits and calderas created by ~250 eruptions. Tectonical
 ly driven extension and tilting of this region created uniquely exposed up
 per-crustal cross sections through caldera-forming volcanic systems and as
 sociated plutonic regions. Mineral chemistry and geochronology through cro
 ss sections of multiple Oligocene calderas in central Nevada reveal change
 s in temperature and volatile content in the magma storage regions leading
  up to and following major eruptions. Though long extinct\, these volcanic
  systems offer insights into magma storage regions that can inform our und
 erstanding of magmatic activity at modern explosive silicic volcanoes.
