Calderas - Genesis, Evolution, and Eruption of Large Silicic Magma Chambers

Explore the genesis, evolution, and eruption of large silicic magma chambers in this comprehensive conference session from the 2012 AGU Fall Meeting. Delve into cutting-edge research on calderas, including studies on Yellowstone, Okataina, Taupo, Mount Mazama, Bishop Tuff, Caetano, and Kamchatka. Learn about innovative techniques such as NanoSIMS geospeedometry for quantifying magma rejuvenation intervals, and examine the amphibole record of caldera cycles. Investigate the dynamics of rhyolitic caldera volcanoes, the building of large magma chambers, and alternative models to standard theories. Gain insights into the petrologic evolution of magmatic systems and the geochronology, volumes, and isotopic characteristics of major caldera-forming eruptions. This 1 hour 47 minute session offers a deep dive into the complex processes shaping some of Earth's most explosive volcanic systems.
