Hi,

not sure what are the latest news on this. There was an article some time ago in Analytical Chemistry, but they used quite a large amount of calcite.

Barker, S.L.L., Dipple, G.M., Dong, F. and Baer, D.S. (2011): Use of laser spectroscopy to measure the 13C/12C and 18O/16O compositions of carbonate minerals. - Analytical Chemistry, 83, 2220-2226, [doi:10.1021/ac103111y].

regards,
Robert
