Commonly, VMS deposits are hosted by only two or three main volcanic units, and thus single-precursor treatments can be applied. However, more complex volcanic systems also exist which are related by continuous fractionation. These are treated using the multiple precursor system, which is similar in principle, but requires a few extra steps to obtain proper mass change results.
