Abstract
Intraplate tectonics and manifestations of magmatism are associated with deep plumes and asthenospheric uplifts (upwelling). The related magmas are represented by layered mafic-ultramafic intrusions, continental and oceanic flood basalts, basic dike swarms, and A-type anorogenic granitoids, to which intraplate or anorogenic ore systems are confined. They can be considered as magma-associated Ni-Cu-PGE, Cr in maficultramafic rocks; magmatic-hydrothermal ore systems confined to anorogenic A-type magmas (greisen Sn-W and Fe-oxide-Cu-Au); hydrothermal ore systems formed in thermal fields associated with the introduction of plume-derived melts into the continental crust. These hydrothermal ore systems include epithermal, igneoussulfide, and exhalation ore deposit types.
