瞬变电磁在可可塔勒铅锌矿床中的应用
|
摘要
可可塔勒铅锌矿床位于阿尔泰山南缘麦兹盆地,是新疆目前发现的最大的铅锌矿床之一。在该矿区部署了2条二维测线,开展了大回线源瞬变电磁数据采集和处理,试图根据所观测的电磁异常圈定深部矿体。对异常解释的钻探验证结果显示,反演结果的低阻异常与实际矿体对应很好,电阻率的空间分布特征与矿体在深部的延伸与地层倾向一致,为该矿区资源潜力评价提供了依据,也是在其它矿区开展类似深部勘探的借鉴。
The Keketale Pb-Zn ore deposit, one of the largest Pb-Zn deposits in Xinjiang, is located in the Maizi basin on the southern margin of the Altai Mountains. This work has deployed two 2-D survey lines in this mine area for data collection and processing of the large-loop transient electromagnetic (TEM) sounding. The purpose is to delineate deep ore bodies in terms of electromagnetic anomalies observed. The drilling verification to anomaly interpretation shows that the low-resistivity anomalies from inversion results correspond well to the locations of real ore bodies in the subsurface. And spatial distribution of electric resistivity values coincides with extension of ore bodies at depth and stratum inclination direction. These results provide evidence for appraisal of resource potential of this deposit. And the trial survey using the TEM technique in this area can serve as a reference for similar work at other deposits.
