Abstract
Role of Fluids in Origin PGE Mineralization’s in the Pansky Tundra Layered Intrusion, Kola Peninsula, NW Russia
Highlights
The Pansky Tundra layered intrusion belongs to a group of the Paleo Proterozoic layered intrusions (2.45-2.50Ga) located in the north-eastern Fennoscandian Shield, Kola Peninsula (Russia)
Ore-bearing altered pyroxene anorthosites are composed by two successively-formed metasomatic association: 1) replacement of pyroxene by tremolite and magnetite; 2) epidote-zoisite-chlorite-albite-sericite-quartz association in the paragenesis with the sulphide-PGE mineralization
The REE patterns of ore-bearing anorthosites are characterized by positive Eu-anomaly and lower contents of HREE
