Magmatic Plumbing Of A Large Permian Caldera Exposed To A Depth Of 25...

Published on Friday, 3 July 2009 05:00 from ScienceDaily

Large volcanic calderas, aka supervolcanoes, are enormous craters tens of kilometers in diameter produced by giant, explosive eruptions that rank among the most violent geologic events. Geophysical studies of recently active calderas and investigations of their eruption products suggest that their magmatic systems are driven by intrusion of mantle-derived basalt in the deep crust, a process commonly referred to as magmatic underplating.
