Is there a way to do kinetic isotopic exchange as in Druhan et al. GCA 2013? I have a system that recrystallizes calcite due to hot fluid circulation and I've read some papers that look at closure temperatures for isotopes. Currently I have a kinetic transformation from a (segregated) low ordered to a (unsegregated) hydrothermal calcite. I was just wondering if there was a cleaner way. Crunchflow, as used in the original paper, doesn't do heat flow for some reason and so isn't an option.
