New ore-magmatic ring-type structure in the Muzkol-Rangkul anticlinorium, Central Pamir

Background . The minerogenic specialization of the Muzkol-Rangkul anticlinorium consists in industrial gemstone deposits ruby, cordierite, almandine, aquamarine, topaz, tourmaline, scapolite, etc. Large ore objects this area are unknown. Until recently, has had a negative assessment terms rare, rare earth, and noble metals. Aim To justify identification previously unknown magnetic ring-type structure to study associated geochemical anomalies. Materials methods Rock mineral samples collected at Chernogorskoye deposit 2016 2018 were examined. composition determined using Polam-R211 petrographic microscope confirmed by XRD analysis DRON-3M diffractometer (analyst A.V. Fedorov, Sergo Russian State University for Geological Prospecting). chemical was studied X-ray microanalysis Cameca SX 100 instrument N.N. Kononkova, Vernadsky Institute Geochemistry Analytical Chemistry). compositions rock an fluorescence spectrometer AXIOS Advanced T.G. Kuzminа, Results A intrusion composed hornblende peridotites, hornblendites, gabbroids identified anticlinorium, gem scapolite deposit. here contact metamorphic rocks Sarydzhilga formation along ring fault. anomalies Co, Ni, W, Nb, Ti, REE revealed contour its periphery.
