GBC：Tracing Cation Exchange Processes at Earth’s Surface Using Mg Isotopes

Di Cai*, Shouye YangState Key Laboratory of Marine Geology, Tongji University, 1239 Siping Road, Shanghai 200092, PR ChinaAbstractInvestigations into the interaction between rock (sediment) and water at Earth’s surface have primarily focused on mineral dissolution/precipitation processes. While the presence of exchangeable cations on mineral surfaces has long been recognized, the coupled chemical evolution of this labile pool with surface water remains less understood. In this study, we demonstr
