Tungsten-molybdenum and tin-polymetallic deposits and occurrences of various types (skarns, quartz veins, disseminated-veinlet stockwork), occurring in the contact zone of alkali-rich and calcium-poor biotite granites with elevated rare metal (Li, Rb, Nb, Ta) contents. The ore field also hosts several iron deposits and rich vein-type fluorite deposits.
