Dear Kathy,
I agree with Clemente, try fractional extraction. Two more papers may
be of interest :
Rosenbaum J. and Sheppard S.M.F. (1986) An isotopic study of siderites,
dolomites and ankerites at high temperatures, Geochim. Cosmochim.
Acta, 50, 1147 - 1150.
Szaran J., Niezgoda H. (1996) Acid fractionations of 18O and 13C in
CO2 preparation from dolomite - calcite mixture, Abstracts of Isotope
Workshop III, Acta Geol. Hung. Suppl., 39, 180 - 181.
With best regards,
