These feedback reactions not > only affect porous rocks but aid porosity and permeability generation in > low-permeability rocks, fundamentally influencing element transport > properties and rheological behavior. These processes can be observed in a > wide variety of systems, some examples being (1) peridotite hydration to > form serpentinites, (2) the dehydration of serpentinite during subduction > or clays during diagenesis, (3) rock weathering at the Earth?s surface, > (4) maturation and primary migration of organic matter in sedimentary > basins, (5) in-situ carbon dioxide fixation via mineral carbonation, (6) > salt damage and (7) decomposition reactions of sedimentary rocks during > the emplacement of magmas. In other words, any mineral (replacement) > reaction that generates porosity at the reaction interface or causes > fracturing due to volume changes. This session seeks to address the > processes that couple rock deformation and geochemical reactions, as a > result of phase transitions or (fluid-mediated) mineral reactions, with > investigations from the Earth?s interior to the surface. Contributions > from field observations, microstructural descriptions, laboratory > experiments, and numerical or theoretical approaches are welcome. > More information is available at: > http://goldschmidt.info/2013/ > > > We are looking forward to meeting you in Florence and apologizes for > multi-posting. > > > On behalf of the conveners > > Regards > > Oliver Plümper > > > > Dr. Oliver Plümper|Assistant Professor|Department of Earth Sciences| > Utrecht University|Budapestlaan 4, 3584 CD Utrecht|tel.
