摘　　要：丹凤矿田作为我国伟晶岩型铀矿的重要产地,有其特殊的成矿条件和控矿因素,笔者通过对铀源地层、伟晶岩脉、地面放射性异常、水系沉积物铀含量异常等预测要素的组合分析,利用MRAS软件圈定并优选出Ⅰ、Ⅱ级远景区各2处,Ⅲ级远景区1处;认为光石沟和陈家庄远景区深部及外围有着十分广阔的找矿空间,桃坪和石门远景区是开辟新找矿方向的有利地段。As an important base of pegmatite type uranium deposit in China,Danfeng orefield has its special metallogenic condition and ore-controlling factors.Through the comprehensive analysis of prediction elements,such as uranium source formation,pegmatite vein,ground surface radioactivity anomaly,stream sediment uranium anomaly,we had outlined two prospective areas of classⅠandⅡ,one class Ⅲ prospective area respectively with MRAS software.The deep and peripheral part of Guangshigou and Chenjiazhuang deposits are the most beneficial space for further prospecting.Taoping and Shimen prospective area are the new favorable ore-forming regions.
