Mardi 27/02/2018 à 14h en salle des séminaires, Erwan MARTIN (ISTEP Paris) présentera ses travaux sur : Multi O- and S- isotope insight into volcanic sulfate aerosols formation and its impact on the atmosphere. The impact of volcanic eruptions on the climate has been studied for the last decades and the role played by sulfate…
Fractionation of fluorine and chlorine during subduction zone metamorphism and arc magma composition Abstract: Fluorine and chlorine are found in magmatic gas/fluid phases in trace quantity along with H2O, CO2, and SO2. Because of halogens' sluggish volatility, compared to H2O and CO2, fluorine and chlorine are ideal geochemical tracers of the magmatic volatile component for the subduction zone…
VolcaPot 5 Mars 2018 à 14h: deux présentations. Sara Di Salvo: Unravel magmatic system dynamics through in situ isotopic micro-analyses: insights into the Campanian Ignimbrite activity (Campi Flegrei, Italy) Large compositional variations in ignimbrites reflect significant zoning in shallow magma reservoirs and represent an excellent source of information on magma storage conditions and volcanic evolutionary…
Le mardi 6 Mars à 14h dans l'amphi du LMV, Roberto Agrusta (LGTPE Lyon) présentera ses travaux sur : Slab-transition zone interaction: what drives and resists plate sinking through the transition zone In the present-day Earth, as subducting plates reach the base of the upper mantle, some appear to flatten and stagnate, while others seemingly…
