| 摘 要： | 赤城县独石口地处沽源中生代火山盆地南部塌陷内,其火山构造活动强烈,铀成矿地质条件优越,铀矿化异常线索丰富。铀矿化主要产于晚侏罗世潜火山岩内部及其内外接触带,受断裂构造及潜火山岩复合控制,与赤铁矿化、硅化、萤石化、水云母化、绿泥石化等蚀变关系密切。通过对地层、潜火山岩体、构造、航放、遥感铁染及羟基蚀变异常等成矿条件进行分析,认为研究区具备较好的火山岩型铀矿找矿前景,圈定一级远景区3处,二级远景区2处,对该区进一步找矿具一定的指导意义。

| Abstract: | The Dushikou area of Chicheng County is located in the Dushikou volcanic collapse basin in the southern of Guyuan Mesozoic basin with strong volcanic activity.Here is superior in uranium metallogenic condition and many U anomalies occur.The mineralization is mainly distributed at inner and outer contact zones of the Late Jurassic subvolcanics and is controlled by both of fault and subvolcanic rock and often closely associated with hematitization,silicification,fluoritization,hydromicazation,and chloritization.According to the analysis of metallogenic condition such as strata,subvolcanic rock,structure,airborne radiometric anomly,iron stain and hydroxyl alteration information the area is potential for volcanic-type uranium deposit and 3 target Ⅰ and 2 targe Ⅱ are delineated for further prospecting. |
