...Adam Kent Whether such periods of magma residence at relatively cold temperatures also occur in supervolcano systems is an interesting question. For their diffusion calculations, Pamukcu et al. use temperatures based on independent petrological estimates of the temperature of formation of quartz...

... inferred from seismic data at active supervolcanoes. The connection of magma batches vertically distributed over several kilometers in the upper crust would cause a substantial increase of buoyancy overpressure, providing an eruption trigger mechanism that is the direct consequence of the reservoir...

... with extreme hazard and environmental impact at all scales, they are the windows through which we may view batholith formation, and their magmatic systems are vital to the evolution of the continental crust. Recently, attention has focused on CFEs and their relation to supervolcanoes and the volcano-plutonic...

...Ashton F. Flinders; David R. Shelly; Philip B. Dawson; David P. Hill; Barbara Tripoli; Yang Shen Abstract A little more than 760 ka ago, a supervolcano on the eastern edge of California (United States) underwent one of North America’s largest Quaternary explosive eruptions. Over this ∼6-day-long...
