黑龙江省奋斗地区变质岩型铀矿成矿条件和控矿因素分析

Analysis of metallogenic conditions of metamorphic rock type uranium deposits and the ore controlling factors in Heilongjiang province Fendou area

通过对奋斗地区延军山铀矿点、铀矿化异常点进行梳理,总结了研究区内典型铀矿化异常特征,并通过对研究区内铀矿化异常进行野外调查、评价,分析了区内变质岩型铀成矿条件和主要空旷因素,指出研究区变质岩型铀矿受古元古代东风山岩群石墨片岩、北西向断裂、伟晶岩复合控制,提出了"石墨片岩+构造+伟晶岩+异常"的找矿思路,并圈定了找矿远景区域,为进一步找矿工作提供了借鉴。

Based on the research on Yan Junshan uranium ore and uranium mineralization anomalies in Fendou area of Hei Longjian province, the author found the features of typical uranium mineralization amomalies. Then the author analyzed meta morphie uranium metallogenie conditions and the main ore controlling factors via field investigation and evaluation, besides, pointed out the metamorphic uranium ore was controlled by graphite schist and north west trending fault and pegmatite of Dongfeng moutain in paleoproterozoie era. Finally, the author proposed one new compound prospecting idea of graphite sehist＆ strueture＆ pegmatite＆anomalies and figured out prospect area, but provided reference for further prospecting.
