摘要
对莫海拉亨铅锌矿床的地质特征及成矿地质条件进行了分析研究,为进一步探讨找矿标志和找矿潜力提供基础研究。初步圈定4条锌(铅)矿体;矿石类型主要为方铅矿(闪锌矿)褐铁矿,其次为黄铁矿褐铁矿;矿石矿物主要有方铅矿、闪锌矿、黄铁矿、褐铁矿;石炭系、二叠系是主要赋矿地层,赋矿层位与北西向断裂密切相关,北西西向断裂控制着矿区内地层和矿化带的展布;北西西向断裂与北东向断裂交汇处为最佳找矿部位,构成重要的控矿作用,成矿条件优越。反映研究区及外围铅锌多金属矿找矿前景广阔。
The geological characteristics and ore-formation geological coudition in Mohailaheng Lead-zinc deposit are analqzed in this paper and this will provode a researching foundation for searching a prospeeting simbol and the exploration pofential.Currently,4 Lead-zinc ore bedies have been divided and the main ore type is galena ore（sphalerife）limonife,the secondory type is pyrife and limonife,The well-ore minerals are mainly galena,sphalerife,pyrife and limonife and the carboniferous and permian are the main ore-formation layers and its euabling seam position is relafed to the NW divection foacture,The NWW divection fracture controls the mainland distribution of the mine layer and the mineralized zone,The best prospecting location is in the interse ction area between the NW direction fracture and the NE direction fracture,This area has a good are-formation condition and good prespecting perspectine.
