Description

The ICDP drilling on Mutnovsky vulcano is focused on the investigation of the interaction between active magmatic and adjacent hydrothermal systems. The identification of magmatic component in fluids and the determination of the overall volatile budget of the volcano are crucial for the understanding of magmatic and hydrothermal processes ongoing in the volcanic system. The proposed project should contribute new constraints on the pre-eruptive conditions, especially on the pressures (depths), temperatures and volatile contents in the magmatic chamber of Mutnovsky volcano. These constraints will be obtained from high pressure - high temperature experimental investigations on phase relations and volatile solubilities in basaltic magmas and from the studies of natural samples, in particular melt inclusions in olivines, collected from the erupted rocks and drilled by the ICDP. These data can be used to constrain a general genetic model of the formation of island arc tholeiitic series and will provide estimates on the budget and contribution of magmatic volatiles to the magmatic-hydrothermal system of Mutnovsky.
