As one of the most important geodynamic systems, mantle plumes are not only responsible for the generation of large igneous provinces, but are also associated with many economically important mineral deposits. Plume-related magmatic sequences are found to host some specific mineralization, notably, mafic-ultramafic layered intrusions and deposits of Cr-Ti-Fe oxides and Ni-Cu-PGE sulfides, komatiite and related Fe-Ni-Cu deposits, anorthosite and Fe-Ti-V oxide deposits, peralkaline complex and Nb-Ta-Zr-REE deposits, and kimberlite and diamond. We are able to identify the following as key controlling factors in plume-related mineralization： structure of a plume, magma source, crystal fractionation, sulfide saturation, crustal contamination, and intrusion processes. Reviews are also given for outstanding issues on the studies of plume-related mineralization and for some potential diagnostic geochemical indicators of mineral prospecting/evaluation （e. g. , Ni in olivine, Cr in elinopyroxene and magnetite, PGE concentration and Re-Os isotopes of layered intrusions）.
