Division/Committee: [GEOC] Division of Geochemistry

Recent developments in experimental and modeling techniques have had a huge impact on geoscience research. High flux neutron and X-ray sources enable in situ observations of nonequilibrium processes such as phase transformations on flat surfaces and in complex porous matrices. Large scale molecular simulations and highly resolved pore scale simulations give us an unprecedented ability to quantitatively test hypotheses regarding processes at the mineral-water interface. However, the connection between experiments and simulations remains an important challenge for geoscientists. In part, this is due to the large range scales associates with these processes and the heterogeneity of geomaterials. This session focuses on how the data from experimental and modeling studies can be successfully utilized for testing hypothesis and validating theories. In specific, how experimental observations can validate modeling techniques, indicate novel unconsidered phenomena, and help to understand complex chemical mechanisms occurring on mineral surfaces. We are specifically interested in contributions that incorporate modeling or experiments at the pore scale. Studies that use molecular-scale-derived understanding of mineral and liquid solution properties to fill the knowledge gaps in pore-scale studies are also encouraged. We welcome submissions that combine characterization, experimental, data processing, and modeling methods to explain mineral reactivity in CO2 capture and transformation, contaminant remediation, and other subsurface geochemical applications.
