Abstract
The composition and isotopic-geochemical peculiarities of zircons from the ore-bearing ultramafic-mafic intrusions of western Taimyr that are promising for finding Pt-Cu-Ni mineralization were characterized for the first time. The similar U-Pb age of zircons from the Binyuda and Dyumaltei intrusions (248.3 ± 13 and 244.4 ± 2.4 Ma, respectively) indicates that the intrusions were formed almost synchronously with tholeiitic basalts of the Siberian Platform. The age and Nd-Sr data of intrusions of western Taimyr are distinct from those of economic ore-bearing intrusions of the Noril’sk province characterized by long-term magmatic evolution of the rocks and different material sources.
