“…to establish unifying themes in our understanding of water, silicate melts, and their chemical combinations in the form of aqueous solutions of hydrous melts over a wide range of pressure and temperature…recent results have challenged our compartmentalized view of geofluids as either silicate liquids or aqueous solutions and our view of the earth as being divided between a wetter, cooler surface and a drier, hotter interior.”

Co-chairs Randy Cygan (SNL), Jim Kubicki (Penn State), David A. Dixon (Alabama) “…Most geochemical reactions near the Earth’s surface and in the crust involve fluid phases and take place at fluid-solid interfaces or in confined spaces of mineral interlayers and nanopores. These …. important natural processes… are inherently multi-scale in time and space, and addressing the … problems they pose requires … the use of new computational science methodologies. A molecular-level understanding of the chemistry and physics of interfacial and confined aqueous solutions interacting with mineral surfaces is essential to understanding many of the crucial problems in energy and the environment… There is a growing consensus that the idealized mineral-fluid interfaces used in MD and MC simulations and the relatively small assemblages used in these models and in quantum calculations are at least an order of magnitude too small in characteristic length (three orders of magnitude in volume) to effectively address many critical questions ”

chemistry and isotope geoscience, 2010 Co-chairs: John Eiler, Bill Goddard (Caltech), Edwin Schauble (UCLA)
“…The nuclear, physical and biochemistry of isotopes have profoundly influenced the geosciences: They are the ultimate foundation of geological time scales, reconstructions of past climate, ‘tracer’ studies in the hydrosphere and atmosphere, and numerous other applied disciplines…. . Stable isotope geochemistry is in the midst of a sustained burst of analytical innovation and observational discovery … It has accumulated many peculiar new observations and is attempting to interpret them with familiar but decades-old physical and chemical theory. Chemistry has undergone a variety of recent innovations, including a striking jump in sophistication and demonstrable accuracy of first-principles theoretical modeling, particularly of complex structures and interfaces. This body of work succeeds on its own terms, but appears to be largely unaware of the set of new, often mysterious, observations coming from novel branches of stable isotope geochemistry.
