UDC 553.493.6:549.32/.33.02(571.5) AU-AG-TE-BI-REE-U MINERALIZATION OF THE MUGUNSKY ORE OCCURRENCES IN THE ALLAKH-YUN METALLOGENIC ZONE
G. S. Anisimova, L. A. Kondratyeva
Detailed mineralogical research of the Mugunsky ore occurrences is conducted. As a result of the study the material constitution is specified and significantly supplemented. Maldonite, hedleyite, berthonite, pentlandite, cobaltite, rare earth minerals of monazite and allanite group, as well as uranium minerals from the group of brannerite are identified for the first time. Compositions of many known minerals are determined. A native gold fineness of various mineral associations is specified. The metallizing process is characterized by a complex (Au-Ag-Te-Bi-REE-U) mineralization.
Key words: maldonite, hedleyite, pentlandite, cobaltite, bismuth and molybdenum oxides, rare earth minerals, group of brannerite, Mugun.
