Steady state models of stable isotopic distributions

This study reviews common calculations and mathematical models used in stable isotopic studies. Some approximations are adopted to simplify the algebra for use in steady state models, with more rigorous mathematics outlined in an Appendix. Review shows that steady-state isotopic models are easy to construct, provide good approximations of system behavior, and are very helpful in evaluating isotopic cycling in many kinds of systems.
