摘要
东卡尔阿依铅锌矿位于西天山赛里木湖以南,属赛里木湖铜铅锌金成矿带,赋存于中元古界青白口系碳酸盐岩地层中,岩控和层控特征明显,与岩浆活动无明显联系。成矿带矿石品位高,矿石矿物以菱锌矿为主,具富锌少铅特点。青白口系属台地相沉积环境,为镁、硅质碳酸盐岩夹碎屑岩建造。通过总结该矿点矿化特征,结合赛里木湖周边1∶5万化探异常特征,认为中元古界青白口系是该区寻找铅锌矿最有利层位。
The Pb-Zn ore of Dongkaerayi is located in the south of Sailimu Lake in the West Tianshan,It belongs to Sail-imu Lake Cu-Pb-Zn-Au copper and metallogenic belt.It mainly associated with Neoproterozoic Qingbaikou Period car-bonate formation,the rock-and strata-controlling characteristics were significant,and it is not obvious and direct contact to the magmatism.The ore grade is high,its mineral constituents is smithsonite,which is rich in zinc and less lead.Its depo-sitional environment was platform facies in the Qingbaikou Period,which is magnesium-quartz carbonate rock construc-tion with fragments rock construction.We figured the cretaceous of Qingbaikou Period are the favourable formations for searching Pb-Zn deposits in the region,by concluded the mineralization features of the Dongkaerayi ore,and analysed the regional geochemical anomalies of the Sailimu Lake area.
