The new progress on polymetallic studies in Daxinganling——The revelation of the southern bank Xilamulun river Molybdenum polymetallic belt

Along the southern bank of Xilamulun River, which located in the Caledonian fold belt of the outer rim of the northern margin of the North China Craton, a 200km long molybdenum polymetallic metallogenic belt has been found in recent years. The new metallogenic belt should be an important molybdenum polymetallic metallogenic belt after Xiao Qinling and Yanshan-Liaoning molybdenum metallogenic belt in China. Preliminary study on three representative ore deposits of the belt shows that ore-forming main relates to magmatic activities in Yanshanian period. Several advices about further research work have proposed since weak basic study on the belt.
