Assoc Prof Fidel Costa Rodriguez

Fidel COSTA is a Principal Investigator with the Volcano group at EOS. He
is an igneous petrologist and geochemist specializing in volcanic
processes. He studied Earth Sciences at the University of Barcelona (Spain), and
received his Ph.D. from the University of Geneva (Switzerland). He was
Marie Curie Fellow (CNRS, Orleans), and subsequently held positions as a
Post-Doctoral Fellow at Ruhr-University, Bochum (Germany), and at the CSIC
in Barcelona (Ramon y Cajal Fellow). He has been involved in developing
new geochronological methods to determine the rates of volcanic and
magmatic processes occurring on human time scales.
Research Interests
I'm interested in understanding the formation, transport, and eruption of magmas
(silicate melt, gas and crystals) on the Earth's surface. Main focus are the conditions
(pressure, temperature, volatile contents) at which magmas are stored prior to
eruption, the processes that lead to the erupted magma compositions
(magma mixing, crystallization), the rates and time scales at which these
processes occur, and, finally how all this information relate to volcanic monitoring
data and unrest phenomena. I have expertise and use a large variety of geochemical
(SEM, electron microprobe, SIMS, FTIR, LA-ICP-MS, XRF, INAA), experimental
(high pressure and temperature apparatus for phase equilibria),
and modeling (finite differences for kinetics in solid state) approaches.
