Characteristic relationships between chemical reaction rate and isotope fractionation factor are often obscured or easily misinterpreted in natural environments. This ambiguity can be substantially reduced where and when it is possible to combine multiple isotopic constraints within the environmental system, e.g.δ18O andδ13C in epikarst,δ34S andδ18O in marine sulfate. Separately, numerical multi‐component reactive transport models are becoming increasingly utilized to deconvolve the stable isotope signatures observed in natural environments. To date, analyses of multi‐isotope systems using isotope‐enabled reactive transport techniques are only just beginning to emerge, though the approach was suggested over a decade ago. Here, we demonstrate the development of a multi‐isotope reactive transport simulation to show how complex signatures can be parsed into physical and chemical factors. We present a hypothetical system using an isotope‐enabled reactive transport model to leverage the coevolution of sulfur and calcium isotope ratios as they fractionate in open, structurally heterogeneous environments.
