摘　　要：大兴安岭地区发育包括碱性钙碱性岩石等的多种类侵入岩与火山岩,具有铌钽成矿的地质条件,但是总体找矿工作程度较低.区内产出面积较大的铌元素化探异常,说明大兴安岭地区具有较好的找矿远景.通过对大兴安岭地区区域地质特征和已发现矿床地质特征的介绍,对该区铌钽化探异常及找矿潜力进行了初步分析,并提出了铌矿找矿的技术方法.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.
