ISOTOPE-GEOCHEMICAL CRITERION IN SEARCH FOR THE NORIL'SK-TYPE MASSIVE PGE-CU-NI SULPHIDE ORES: CONSTRAINTS FROM PB, ND AND SR ISOTOPE DATA

Abstract

Our study aims on isotope-geochemical speciation of main types of intrusive bodies at Noril’sk district (northern Siberia), with particular focus on isotope-geochemical estimation for the unique metallogenic potential of the Noril’sk-type intrusions that range in thickness to 360 m and length to 25 km.
