摘要：

新疆托克赛铅锌矿床位于伊犁—伊赛克湖微板块赛里木地块，矿体赋存于下元古界温泉群碳酸盐岩中，含矿层延伸稳定，矿体呈层状顺层产出，矿石主要呈条带状、纹层状构造，矿石矿物组合简单，分析认为其成因类型属碳酸盐岩容矿的沉积－变质型铅锌矿床。矿区处于1∶20万水系沉积物及金属量测量异常区内，1∶5万水系沉积物测量在矿区内圈出了Pb-Zn-Ag综合异常，主成矿元素Pb、Zn异常面积大，强度高，套合较好，与地表铅锌矿化体对应极好。激电扫面圈出的中低电阻、高极化率异常反映了地表及浅部铅锌矿化体分布范围，瞬变电磁测量高磁变率异常可以较好地指示中深部富矿体的存在。在综合分析矿床成矿地质条件、地球化学、地球物理异常特征的基础上，初步建立了矿床的地质－地球化学－地球物理综合找矿模型。

Abstract:

Tuokesai lead-zinc deposit is located in Sailimu block, Yili-Yisaike lake microplate. The ore body hosted in Lower Proterozoic Wenquan group carbonate rock. The ore bearing bed extends steadily and the ore body occurs along the strata with bedded, presented banding and lamellar feature. Leadzinc ore mineral association is simple. On the basis of analysis the genetic type belongs to sedimento-metamorphic deposit which is hosted in carbonate rock. Mining area is located in 1∶200,000 stream sediment survey, metallometry and placer abnormal area. Pb-Zn-Ag composite anomalies are delineated in this area. Pb and Zn as main mineralizing elements have anomalies of large area, high strength, good superposition; and earth's surface lead-zinc mineralization body correspond to these anomalies well. IP scanning mid-low resistance and high polarizability reflect earth's surface and shallow leadzinc mineralization body. Transient electromagnetic measurements for high susceptibility abnormalies reflect deep oreshoot. Based on comprehensive analysis of ore-forming geological conditions, geochemistry and geophysical abnormalies, we establish geological-geochemistry-geophysical prospecting model preliminarily.

Key words: Tuokesai lead-zinc deposit, comprehensive prospecting model, Wenquan County, Xinjiang
