Geochemical Model of Genesis of the Kingash Platinoid-Copper-Nickel Deposit

摘要

Kingash ore field with the deposit of the same name is located within the Archean Kan block of Eastern Sayan and does not go beyond the boundary of the new nickel- and platinum-bearing province with numerous ore-bearing massifs [1]. In plan the Kingash massif forms a lens (Fig. 1) comprising two "megalayers": lower peridotite-pyroxenite-serpentinite and overlying gabbroid. In section it presents lopolith with a geo-physically reflected gravitational stage approximated with a multichamber incurrent canal [3]. Ultrabasic rocks of the massif contain Pechenga-type sulfide ore of chalcopyrite-pentlandite-pyrrhotite composition.
