| 摘 要： | 哈尔达坂铅锌矿床位于西天山西段别珍套山一带,属赛里木铜、铅锌、铌、钽、钨、磷成矿带,矿体赋存于中元古界长城系一套浅变质的海相陆源碎屑岩及碳酸盐岩中;含矿层延伸稳定,主要矿体呈似层状、透镜体状顺层产出。矿石具条带状、角砾状、浸染状构造;矿石中金属矿物主要为方铅矿、闪锌矿;脉石矿物主要为方解石、白云石,矿石矿物组合简单,与哈萨克斯坦捷克利层控型铅锌矿床对比,矿床的产出环境、形成时代、赋矿层位、矿体特征、矿石质量特征等均极为相似。初步分析,认为其成因类型均属层控型,该类型铅锌矿床在西天山前寒武纪地层中属首次发现,证实了捷克利层控型铅锌成矿带向东延至我国新疆境内赛里木湖一带,对本地区今后的铅锌找矿工作具有十分重要的意义。

| Abstract: | The Haerdaban lead-zinc deposit is located in the Biezhentaoshan area of west part of the Western Tianshan, which belongs to Sailimu Cu, Pb, Zn, Nb, Ta, W and P metallogenic belt. Ore body, which is stable extension, occur in the low-grade metamorphic marine clastic rocks and carbonate rocks of the Middle Proterozoic Changcheng System. The main ore body is beds-, lens-like bedding output with banded, brecciated, and disseminated structure. Metal minerals in the ore are mainly galena and sphalerite. Moreover, mineral assemblages in gangue are simple, including calcite and dolomite. Compared with the Jiekeli strata-bound lead-zinc deposit in Kazakhstan, the Haerdaban lead-zinc deposit is similar to formed settings, times, locations, ore that its genetic types are stratabound type, which western Tianshan. It is confirmed that the Jiekeli area, Xinjiang, China. Furthermore, it is of great the future. characteristics and quality. Preliminary analysis shows is discovered for the first time in Precambrian strata of strata-bound lead-＇zinc deposit extended east to Sailimu significance for lead and zinc exploration of the region in the future. |
