文摘

•: Trace element composition of magnetite from 16 VMS deposits, host bedrocks, and VMS-associated banded iron formations are documented.
•: Partial least squares discriminant analysis, a supervised classification technique, is used to classify LA-ICP-MS data of magnetite from various VMS settings.
•: PLS-DA of magnetite compositions from various VMS settings yields models that classify magnetite in unconsolidated sediments.
•: Magnetite chemistry discriminates VMS deposits from other mineral deposit types.
