Contributions on any topic related to Geochemistry of Hydrothermal Systems, including the field observations, laboratory experiments, methodological innovations in the field and lab practice may be submitted to this session. Areas studied vary from volcano-hydrothermal to low-temperature sedimentary-hosted systems, terrestrial to submarine, using different techniques ranging from direct sampling, remote sensors, to numerical and laboratory modeling. In the present and recent past, our understanding of hydrothermal processes has been advanced by the
appearance of precise and high-productive analytical techniques, by new fundamental experiments on the water-rock interaction and the pioneering application of new isotopic systems. We invite presentations addressing or raising the important questions on the hydrothermal heat and mass
transport in the Earth crust, hydrothermal metal transport and ore formation, sources and cycling of elements in hydrothermal processes, thermodynamics and kinetics in water-rock and magmatic-hydrothermal interaction, and geochemical case histories for individual hydrothermal
systems including monitoring, exploration and modeling.
