The microstructures, textures, chemical and isotopic patterns in minerals and rocks as well as the compositions of fluid / melt inclusions are of key importance in reconstructing the evolution of geological systems and can now be studied at unprecedented levels of detail. Mineral reactions, deformation and recrystallization, and their interplay with hydrothermal fluids that occur from the surface of the Earth to mantle depths control processes such as melting, degassing, and potentially the origin of life itself. Studying such interlinked processes requires the use of diverse theoretical tools such as equilibrium thermodynamics, kinetics of mineral transformations, and heat and mass transport including processes of fluid-rock interaction. In addition, the nature of processes that occurred in and on the Earth may have changed from the early history of the Earth (Hadean-Archean) to the present day. We invite contributions that address phenomena like magmatic crystallization, metamorphic and metasomatic mineral reactions, chemical and isotopic pattern formation by mineral growth or diffusion-mediated re-equilibration, fluid-mediated mineral replacement, and fabric evolution from dynamic and static re-crystallization. The evolution of the nature of fluids and of fluid related processes over the geological history are of particular interest. We aim to integrate field related, experimental, and theoretical studies and stimulate scientific discussion across the pertinent fields of expertise.
