Dear all, please find below the announcement for *session* *T10-S2.* ‘*Terrestrial Magmatic Systems’ *at the 3^rd European Mineralogical conference (EMC). *Online only! *The abstract deadline is May 31. https://emc2020.ptmin.eu/themes/t10-magmatism-and-volcanology/t10-s2-terrestrial-magmatic-systems/ <https://emc2020.ptmin.eu/themes/t10-magmatism-and-volcanology/t10-s2-terrestrial-magmatic-systems/> *Terrestrial Magmatic Systems* Magmatic processes constitute the main connection between the deep solid Earth and the surface. They are responsible for the formation and differentiation of continents on Earth, for the generation of large ore deposits, and for a wide variety of volcanic eruptions. Magmatic systems are highly dynamic and are formed by many small pulses of magma, of which only a fraction erupts in volcanoes, with most melt crystallizing within the Earth’s crust during its upward flow. In order to understand these systems, they need to be considered at the mantle-to-atmosphere scale and not just by analyzing shallow magma chambers that directly feed volcanoes. This session invites experimental, field-based and numerical modelling studies that address the dynamics of various parts of these complex physical and chemical systems from the deep mantle to the atmosphere, and help to unravel how magmatic processes on vastly different scales and environments (subsurface, surface, atmosphere) are intertwined. *Keynote Speaker: * *Catherine Annen* (Institute of Geophysics of the Czech Academy of Sciences): *‘Magmatic systems regarded as complex dynamic networks’* *Conveners:* Horst Marschall (Frankfurt University) Boris Kaus (Mainz University) Maren Kahl (Heidelberg University) We look forward to your contributions. Best regards, Maren Kahl on behalf of all conveners -- Dr Maren Kahl Universität Heidelberg Institut für Geowissenschaften Im Neuenheimer Feld 234-236 69120 Heidelberg Maren.Kahl@geow.uni-heidelberg.de
