Geodynamic aspects of the metallogeny-magmatic zonality relationship of orogenic volcanic-plutonic belts

Research subject. The orogenic marginal-continental and collisional volcanic-plutonic belts, the zonality of magmatism metallogeny within them, as well relationship endogenous with magmatic geodynamics belt formation. Materials methods include long-term studies Devonian Upper-Paleozoic belts Kazakhstan Cretaceous-Paleogenic Sikhote-Alin; an analysis alterations in material parameters magmatites; identification front rear parts arrangement features metallogenic zones their limits; data on other world. Results. For marginal continental asymmetric change tholeiitic low-potassium magmatites calcareous-alkaline petrochemical series frontal zone into high-potassium branch shoshonite (Devonian Upper Paleozoic Kazakhstan) has been established. In same direction, elemental, genetic type deposits changes: pyrite copper-polymetallic are replaced by molybdenum-copper-porphyry (near border zone) then rare metal ones. This is also characteristic Andean Okhotsk-Chukchi belts. collision characterised symmetrical a from centre to at edges (Mongolia). some cases (Sikhote-Alin Japan), continuity disrupted result mantle diapir (or plume), occurs polymetallic manifestations ocean–continent boundary) rare-metal ones distance. Conclusions. correlates removal ranges transition interior latter. this case, ore formations copperporphyry direction. due subduction processes. situation respect crowding copper along frame. These important for prediction, palaeotectonic reconstructions.
