| 摘 要： | 内蒙古李清地银多金属矿床位于乌兰察布市西南郊,矿床受其北的大脑包山火山构造的控制,矿体充填交代于NE向和NW向断裂中,矿床分为2个矿带、3个矿段,矿体呈扁豆状、囊状、透镜状等,成矿元素显示出南部富银锰,中部为铅锌,北部除铅锌外,银有所降低,铜、金增高的水平分带特点;北矿带西段共有10个矿体,均为NE走向,上部矿体均已成氧化矿;根据成矿地质特点,认为矿床属于与火山-岩浆活动有关的中(低)温热液型充填交代银多金属矿;文章还就矿段、矿床和矿带的找矿远景进行了分析。

| Abstract: | Liqingdi Ag polymetallic deposit is located in the southwestern suburbs of Wulanchabu city.It is controlled by Danaobao volcanic structure.Ore bodies are filling and replacement in NE and NW fractural zones and occur in pocket and lens.There are two ore zones and three ore sections in the deposit.The ore is characterized by horizontal element zoning such as Ag,Mn in the south,Pb,Zn in the middle and lower Ag and higher Cu,Au in addition to Pb,Zn in the north.Ten ore bodies trending all in NE direction are located in the west part of the north ore zone.The upper ore bodies are composed of oxidized ore.According to the geological characteristics,the deposit is the low to moderate temperature hydrothermal filling metasomatic Ag polymetallic deposit related to volcanic magmatic process.In the paper,it also analyzes on the genesis and prospecting potential of the ore domains,the ore zones and the deposit. |
