Abstract :The incorporation of Na^+ into calcium carbonate and protodolomite was studied by precipitating carbonates from Ca (HCO_3)_2 + NaCl(or NaHCO_3) + MgCl_2 solution. Relationship between sodium content of carbonate and Na^+ concentration in solution is obtained as: log[Na]_<carbonate> = n log[Na^+]_<solution> + k (n and k are constants). The addition of NaHCO_3 and/or MgCl_2 to Ca(HCO_3)_2 solution increases the incorporation of Na^+ into aragonite. Incorporation of Na^+ into protodolomite precipitated from brine solution is much higher than that into Mg-poor calcite precipitated from solution having the same Na^+ concentration as that in the brine solution.
