- W2062746313 abstract "PCO2 is a significant influence on the incorporation of MgCO3 in calcite precipitated from seawater and from MgCl2-CaCl2 (aMg2+aCa2+ = 5.7) solutions at temperatures from 5 to 45 °C. In seawater at 25°C, the thermodynamic distribution coefficient, DMg, increased from 0.013 at 10−1 atm to 0.024 at 10−4.5 atm, Pco2 · DMg showed a similar dependence on PCO2 at other temperatures, but trends are offset by temperature effects on DMg. In normal seawater, variations in temperature from 5 to 45 °C, coupled with changes in pco2 from 10−1 to 10−4.5 atm, produce Mg calcite compositions ranging from 6 to 18 mol% MgCO3 · DMg depends linearly on log Pco2, log mHCO3−, and pH at any given temperature. There is no linear dependence of DMg on log mCO32−, growth rate, or calcite saturation state. Overgrowths precipitated from MgCl2-CaCl2 solutions at equilibrium with different PCO2 values showed compositional trends similar to those for seawater except that calcites were always enriched by about 2 mol% MgCO3 relative to compositions in seawater under the same PCO2 and temperature conditions. DMg values also are linearly dependent on pH and log aHCO3− these solutions. The compositional trends in the MgCl2-CaCl2 solutions correlate well with compositions of Mg-calcites precipitated by Mucci et al. (1989) from sulfate-free seawater at 25°C and 10−2.5 atm PCO2. Modern marine Mg calcite cement compositions probably are influenced by local variations in porewater PCO2 and sulfate concentration, as well as by changes in temperature. Global changes in atmospheric PCO2 during the Phanerozoic may influence trends in compositions of ancient shallow marine Mg calcite." @default.
