| 摘 要： | 尤卡朗铅银矿床处于尤卡朗 - 同德铅银多金属成矿带中部,纳木错-嘉黎断裂带北侧.主要控矿条件包括基底地层和构造.主断裂派生的次级断裂构造控制了矿床的定位和空间展布,侏罗纪马里组地层是重要矿源层.后期热事件使成矿元素富集,并在压力驱使下沿构造裂隙上升,在围岩有利地段充填交代形成矿床.根据矿体在空间上的展布和变化规律及异常特征,对矿区边部和深部隐伏矿体进行了预测.

| Abstract: | Youkalang lead-silver deposit in Youkalang-Tongde lead silver polymetallic ore belt in the central,Namucuo-Jiali fault zone on the north side.The main ore-controlling conditions are the basement strata and structure etc.Main fault derived from sub-faults controlled the location of the deposits and spatial distribution,Jurassic Mali Group is an important source bed.Hot events of the late-forming element enrichment,and the pressure driven by rising along the tectonic fissures in the surrounding lots filled fa... |
