Application of Comprehensive Electromagnetic Methods in the Search for Copper–Nickel Polymetallic Ores in Shallow-Covered Areas—A Case Study of The Jing'erquan Area in the East Tianshan Mountains of Xinjiang

  • 摘要: 新疆东天山镜儿泉地区属于浅覆盖区,传统地表地质勘查手段难以准确判断矿体的存在。为克服这一难题,研究采纳磁法、大功率时间域激电法(TDIP)和可控源电磁测深法(CSEM)等先进技术手段进行地下勘查。勘探工作首先通过磁法勘查确定异常区域,进而利用TDIP法评估矿化范围和构造分布,最终通过CSEM法的电阻率断面反演技术,揭示地下构造特征和矿体的空间分布情况。基于综合地球物理资料处理解释,成功圈定2处磁异常区和2处激电异常区。这些成果不仅为镜儿泉地区后续的钻探工作提供科学依据,而且为其他具有类似地质特征地区的铜镍多金属矿床勘查提供宝贵的方法和经验参考。

     

    Abstract: The Jing'erquan area in the East Tianshan Mountains of Xinjiang is characterized by shallow coverage, posing challenges to surface geological exploration for ore bodies. This study utilized a combination of geophysical methods to overcome these challenges. Magnetic anomaly mapping was used initially to delineate areas of interest, followed by the application of the high-power time-domain induced polarization (IP) method to estimate mineralization extents and structural distributions within the mining area. Subsequently, the controllable source electromagnetic sounding method was employed to generate resistivity section maps, revealing subsurface structural characteristics and ore body occurrences. Comprehensive data processing and interpretation identified two magnetic anomalies and four IP anomalies. The results of these applications provide foundational support for future drilling projects within the mining area and offer valuable insights for workers in similar regions seeking copper–nickel polymetallic deposits.
