Complex multi-component fluids are widely involved in a variety of
endogenic processes both in the Earth’s crust and mantle. We plan to
subdivide our joint session into two portions. The first one concerns to
physicochemical properties of crustal fluids, such as their composition,
miscibility range, pH characteristics. Papers devoted to origin of crustal
fluids, experimental and theoretical data on the impact of fluids on
rheological properties of crustal rocks and fluid flow – deformation
relations are welcomed. The second portion of the joint session is planned
to be devoted to the mantle fluids. A special interest of the session is
highly alkalic fluids as leading agents of the mantle metasomatism,
provoking the formation of kimberlites, lamproites, alkaline basalts, and
carbonatites, as well as closely related to the diamond formation. We
greatly solicit all kinds of contributions related to petrological,
geochemical, and experimental evidence for activity of such fluids in the
Earth’s mantle, including phase equilibria involving alkali-rich fluids at
the high-pressure- high-temperature conditions, synthesis of specific
phase assemblages indicative of high alkali activity in the mantle,
partitioning of components between minerals and alkalic liquids, diamond
growth in the alkalic melts, etc. Within our cross-disciplinary Session we
hope to bring together scientists who are doing petrology, geophysics and
geochemistry. It is assumed that papers may be constrained from natural
observations and laboratory experiments. This session is organized and sponsored by the Working Group on Mineral Equilibria at IMA.
