黑山铀矿位于乌兰乌珠尔复式岩体北缘,黑山(骆驼峰)南坡大断裂的南侧(上盘)。大地构造位置属西域板块祁漫塔格北坡―夏日哈新元古代―早古生代岩浆弧带。区内金水口岩群是一套经历了角闪岩相变质作用的火山-沉积岩系,黑云石英片岩 U 背景值10×10-6~21×10-6,华力西期中酸性侵入岩 U 背景值7×10-6~12×10-6,为本区成矿提供丰富的铀源；构造运动具多周期性活动特征,为岩体和金水口岩群中的铀元素活化、运移、富集成矿提供了非常有利的成矿地质条件。工作区已圈出含铀矿化带3条(Ⅰ、Ⅱ、Ⅲ号),Ⅰ、Ⅱ号矿化带最具找矿前景。

Heishan Uranium deposit locates at the north rim of Wulan Wuzhuer complex massif and at the south side (upper side)of Heishan (Camel Peak)southern slope major fault.Its tectonic structure falls into Qimantag Mountain northern slope-Xiariha Neoproterozoic-Early Paleozoic magmatic arc belt of Western China Plate.Jinshuikou Group in this area is a set of volcanic-sedimentary rock series after amphibolitic faci-es metamorphic process.The U background value of biotite quartz schist is 10×10 -6 ~21×10 -6 ,while the U background value of Variscan intermediate acidity intrusive rock is 7 × 10 -6 ~ 12 × 10 -6 ,and they both provide abundant source of uranium for mineralization in this area.The tectonic movement is characterized by multicyclic activity,and it creates a considerably favorable metallogenic conditions for activation,migra-tion and enrichment of Uranium element in rock bodies and Jinshuikou Group.Three uranium-bearing min-eralized belts are blocked in the study area (No.I,No.II,No.III),and the No.I and No.II mineralized belts have the most favorable prospect of prospecting.
