Features of geology and composition of rocks from the alkaline-gabbroid University massif (NE Kuznetsk Alatau ridge, Siberia)

Abstract

This paper discusses specifics of petrography and structural tectonic position of the alkaline-gabbroic University massif, which is a sort of analogue of the Kiya-Shaltyr deposit of nepheline ores in this area that was very slightly eroded. In this work, we will also present new precise analytical data on rare and trace element distribution in major intrusive phases of this geological object, and also isotope dating on the basis of Sm-Nd method.
