Abstract
The article examine petrologic-geochemical and isotope peculiarities of forming low sulfide PGE deposit in Palaeproterozoic layered intrusion Pansky Tundra at central part of Kola Peninsula. PGE mineralization concentrated within rhythmic layered horizons (RLH) lower and upper parts of intrusion’s rocks mostly gabbronorite composition. Main feature rich PGE mineralization is close association with anorthosites and leiconorites located in RLH and subject of later magmatic metasomatic transformations. Isotope U-Pb age of anorthosites 2449 ± 12 Ma, and age of gabbronorites from RLH by zircons - 2491±1.5 Ma. Sm-Nd isotope dating of metasomatic ore bearing rocks shows age corresponding 2427±90 Ma with sign of eNd from -0.7 up to -1.7 and TDM = 2.5 Ga. For detail examination geochemistry ore bearing and host rocks it is applied neutron-activation analysis. Method factor analysis and estimation disposition REE were arranged affinity ore bearing and host rocks with specific of geochemical composition of lower crust. More later anorthosites enriched by fluids with Cu, Ni, PGE in combination with Cl, F, Se, S made executive metasomatic transformation of anorthosites and create possibilities for a forming reef type PGE deposit.
