DOI: 10.1007/s12665-017-7182-8
Abstract: Thermal conductivity is an important parameter to consider when designing clay-based barriers for use in deep geological repositories (DGR). In the DGR environment, the infiltration of local saline groundwater can potentially change the pore fluid… read more here.

DOI: 10.1016/j.gca.2017.07.011
Abstract: Abstract The behavior of Fe during serpentinization largely controls the potential for oxidation-reduction reactions and energy budget for serpentinite-hosted microbial communities. We present Fe isotope data for mineral separates from a partially serpentinized dunite from… read more here.
