Understanding the feedback mechanisms between deformation, rheology, mineral reactions, phase transitions, material transport, and fluid-rock interaction is one of the major challenges in contemporary earth-science research. Within this broad range of interactions, some of the least well understood are processes that have a chemical cause and a physical consequence or vice versa. For example, the net volume change of a reaction must alter the local stress state and hence reaction rate; in pressure solution, stress gives rise to chemical transport on grain and larger scale. Such feedback mechanisms may lead to pattern formation and observed patterns may provide clues to the underlying processes.
We invite contributions that quantify the interactions between the various processes by means of field, analogue, theoretical, or numerical studies. While the focus of the sessions will be on smaller scale processes it is not scale limited due to the importance of the findings for large-scale geodynamics. We would like to emphasize feedbacks that involve some chemical interaction (e.g. pressure solution; fluid pressure influenced by dehydration reactions, reaction induced stress) rather than those which are purely physical in origin.
