The coprecipitation of Na and K was experimentally investigated in aragonite. The distribution functions were determined at pH 6.8 and 8.8 over aqueous Na and K concentrations of between 5 × 10 -4 and 2.0 M and temperatures of between 25 and 75°C. The mole fractions of Na and K in aragonite are related to the aqueous ratios of Na and Ca by a function of the form where C 0 and C 1 are constants at a given temperature. This equation was derived by a statistical model assuming a heterogeneous energy distribution for the sites of incorporation. The independence of the coprecipitation process from aqueous anion activities suggests that carbonate is the only anionic species in the solid solution.
