Magma mixing dynamics and associated geophysical signals
out of 5 stars
08 Oct 2015 | Contributor(s):: Chiara Paola Montagna, Antonella Longo, Paolo Papale, Matteo Bagagli
Primitive, volatile-rich magma arrival from depth into a degassed, evolved reservoir at 3km depth is investigated. The two magmatic end-member mix very efficiently on time scales of hours. The evolution is characterized by very heterogeneous pressure variations in space and time, showing...

Experimental constraints on magma mixing: case studies from Phlegrean Fields and Montserrat

The mixing process in nature is observed at different scales in the rock record, evident through variable structural and textural patterns and morphologies such as filament-like structures, enclaves, and mineral phases showing physico-chemical disequilibrium. The type and geometry of these...
