New data on geology, petrography, isotope geochemistry and PGE mineralization of the Monchetundra intrusion
Abstract. The paper presents new Sm-Nd isotope-geochronological and geochemical data for the ore-bearing rock of the Fedorovo-Pansky Palaeoproterozoic layered complex (Kola Peninsula) and Nottrask layered intrusion (Sweden). For the first time, Sm-Nd dating procedure has applied sulphides as new minerals-geochronometers that allow direct dating of ore-forming events. The resultant ages of 2475В±37 Ma for the gabbronorite of the Fedorovo-Pansky complex and of 1740В±27 Ma for the gabbro of the Nottrask intrusion have been interpreted as the time of ore-forming processes in the two intrusions. Thus, it has been demonstrated that sulphides may be used as minerals-geochronometers for Sm-Nd isotope-geochronological investigations.
