摘　　要：伊春铀成矿远景带地质背景复杂,发育有火山岩型、花岗岩型、变质岩型铀矿化,已发现的铀矿化点集中分布于帽儿山等8处异常区。笔者通过对区内火山岩型、花岗岩型铀矿化特征进行分析,总结了该带铀矿化的区域控制因素,认为前寒武纪富铀地质体、断裂和火山构造,以及层位、岩性和矽卡岩型多金属矿化等因素对铀矿化具有重要的控制作用。在此基础上,提出该带下一步的找矿工作思路。Geological background of prospective uranium metallogenic zone in Yichun is quite complex and developed with mineralizations of volcanic rock type, granite type and metamorphic rock type which are mainly concentrated in 8 blocks in Maoershan area . By analyzing and studying characteristics of typi- cal mineralization in the anomaly area, the controlling factors of volcanic and granite type mineralization was believed to consist of Precambrian rich uranium geologic body, fault structure, volcanic structure, strata and lithologic characters which were related to skarn type polymetallic mineralization were also im- portant to the formation of uranium deposit formation. Based on the above realization, the idea was pro- posed for the future exploration.
