MINERALIZATION OF ALKALI-ULTRABASIC COMPLEXES OF FAR EAST RUSSIA

Special features of geological structure,mineralization and genesis of the Russian Far Eastern alkali-ultrabasic complexes have been examined.Short description of exceptional recently discovered and formerly known deposits is given.In this formation group of complexes,deposits of rare and precious metals (zirconium,rare-earth elements,platinum metals,gold,etc.),precious and ornamental stones,titanium,phosphorus,phlogopite and vermiculite are shown.Original points of view at the genesis of these new genetic types of deposits are suggested.
