The role of water in fault lubrication [PDF]
Nature Communications, 2018 AbstractThe friction between two adjacent tectonic plates under shear loading may dictate seismic activities. To advance the understanding of mechanisms underlying fault strength, we investigate the frictional characteristics of calcite in an aqueous environment.
