The Platiniferous Belt (PB) is situated eastward from the Main Urals Fault and can be regarded as a magmatic trace of the Lower Paleozoic subduction zone. The PB stretches for 900 km north - south as a chain of 14 mafic-ultramafic massifs composed of different associations of ultrabasites (dunites, wehrlites, and clino-pyroxenites), olivine-gabbros, homblende-gabbros, gabbro-norites and subordinately granitoides. Water meta-morphism of amphibolite and green-schist facies developed of mafic-ultramafic pegmatites is caused by the fluid flows (primary — oceanic water) rising from the subduction zone and is widely displayed in the PB. These fluids also caused the migration and redistribution of PGE, including deposits generation.
