Abstract. Along with its impact on calcifying plankton, ocean acidification also affects benthic biogeochemistry and organisms. Compared to the overlying water, fluid composition in sediments is altered through effect of mineralization organic matter, which can further lower both pH carbonate saturation state. This potentially be counteracted by addition minerals sediment surface. To explore biogeochemical effects mineral additions coastal sediments, we experimentally quantified dissolution kinetics, then integrated this data into a reactive transport model that represents early diagenetic cycling C, O, N, S Fe, traces total alkalinity, state CaCO3. Model simulations were carried out delineate type amount added, porewater mixing matter rates alkalinity flux water. results showed added undergo initial rapid generate saturated conditions. Aragonite led higher concentrations than calcite. Simulations environments low exhibited significant increase compared high CO2 production rates, highlighting environment-specific extent buffering effect. Our work indicates have potential effectively buffer surficial over multiple years, yielding conditions counteract detrimental OA larval recruitment, fluxes support marine carbon dioxide removal (mCDR)
