COMPOSITION, STRUCTURE, AND AGE OF THE NARYN ALKALINE SYENITE MASSIF: INSIGHTS INTO THE DIVERSITY OF RARE-METAL ROCKS IN SANGILEN

Russian Geology and Geophysics
Massifs of alkaline granitoids and nepheline syenite are widespread in Eastern Tuva and are frequently associated with rare-metal deposits and occurrences, which formed mainly during the Late Carboniferous and Permian. The Naryn massif comprises nepheline syenite of the main phase, rocks of the contact zone, and a complex of three types of foidite ...
