PRELIMINARY STUDY ON THE PROSPECTING POTENTIAL OF NIOBIUM-TANTALUM DEPOSITS IN DAXINGANLING REGION

Kinds of intrusive and volcanic rocks, including alkaline and calc-alkaline rocks with metallogenic conditions for niobium and tantalum deposits, are developed in Daxinganling region. However, the prospecting work is generally poor. Large area of Nb geochemical anomaly shows a good prospecting potential. Based on the discussion of regional geology and characteristics of the ore deposits in Daxinganling area, the ore prospects in this area is preliminarily analyzed. The technical method of prospecting is also proposed.
