Abstract A technique is described for the total extraction of oxygen from calcium carbonate for isotopic analysis. This permits recalculation of previously published data to yield absolute values of equilibrium constants for the oxygen isotope exchange reaction between calcite and water. The equilibrium constunt varies with temperature according to the empirical relationship lnK = 2730 T<sup>-2</sup> - 0.00256 over the temperature range 273 to 1023 deg K.
