"Dynamics of transcrustal magmatic systems, and their consequences on volcanic behaviour”.
"Dynamics of core-mantle differentiation and equilibration" The basic structure of the terrestrial planets - an iron-rich metallic core surrounded by a silicate mantle - has been set during the accretion of the planets, when the high temperature allowed the metal and silicate phases to melt and separate. The amount of transfert of chemical elements and…
Regional Tephrostratigraphic Frameworks: Applications and Challenges https://youtu.be/bpkuX6UdjaE Detailed stratigraphic studies of pyroclastic deposits form arguably the best tool to estimate the frequency and magnitude of explosive eruptions at volcanoes where limited or no historical records exist. As such tephrostratigraphy forms a first-order assessment of potential future eruptive behavior at poorly known volcanoes. Alternations of…
