Dear Thomas and others interested,

>I am looking for oxygen isotope fractionation factors between calcite and

>values of dolomite for differences in the dolomite-CO2 fractionation.
>............

Also check out Swart et al. (1991; Chem. Geol. (Isotope Geosc. Sect.) V. 86, 
p.89-96). They compare acid fractionation factors at 25 to 90 deg C for a 
number of different techniques.

Greetings,
