V007:
Deep Earth Watery Metasomatic Fluids





Session ID#: 26130

Session Description:
Water-bearing fluids play an important role in a wide range of mantle processes. The fluids vary from dilute to over 50% dissolved silicate-rock components and assist in the transport of geochemical signals from subducting slabs in arc and back-arc magmas. All silicate systems exhibit full miscibility with H2O at mantle depths, indicating that dehydration “melting” can produce an intermediate, H2O-rich fluid phase with extraordinary metasomatic power. New models of diamond formation point to the presence of an H2O-bearing COH fluid highly charged with rock-forming chemical elements that can equilibrate with eclogite and peridotite. How much of the mantle has been altered by such fluids? We invite contributions from experimental, fluid inclusion, ab initio, and thermodynamic modeling studies, which are providing unprecedented insights into aqueous fluids at mantle conditions.
