There is little evidence for kinetic fractionation on the basis of C and O isotope correlations. C and O isotope ratios do not correlate strongly for any of the three stalag- mites in this study or even for portions of these stalagmites. The highest R2 value for any of the three stalagmites is 0.27 (table S6). Because the top of D4 was deposited in isotopic equilibrium and because a portion of D4 replicates the Hulu record, D4 is less likely to have been affected by kinetic effects or water/rock interactions than D3.
