Abstract

Transform fault zones that are clearly registered in the mantle transition zone in the form of slab boundaries are one of geodynamic factors of formation of large metallogenic provinces in the North Pacific containing jasperoid deposits of gold. It is shown that toroidal currents transporting fluids and heat flows from subslab asthenosphere and undepleted mantle to the upper levels of the mantle and lithosphere occur near slab boundaries. Migration of fluid and heat flows through the mantle wedge to the subslab asthenosphere leads to the formation of ore-magmatic porphyry systems and localization of gold-jasperoid mineralization.
