| 中文摘要: |
| 根据新疆阿奇山地区矿化岩石和围岩间存在明显电性差异的特征，在区内开展了大比例尺的航空瞬变电磁测量工作。本文根据测量结果综合评述了区内航空瞬变电磁特征并筛选了3处航电异常，其中1处航电异常位置与阿奇山铅锌矿相吻合，根据该异常特征推断了矿体的产状及延伸。在重点分析已知矿床地质、航电特征的基础上，在研究区内圈定了两处找矿靶区。航空瞬变电磁法在本区应用效果显著，值得在寻找与低阻体有关的铅锌多金属找矿工作中推广应用。 |
| 英文摘要: |
| According to the distinct geophysical differences between mineralized rocks and wall rocks in the Aqishan area of Xinjiang, an airborne transient electromagnetic (ATEM) survey on a large scale has been conducted in this area. This paper presents a comprehensive review on this measurement and chooses three anomalies from it. It is found one anomaly position is consistent with the Aqishan lead-zinc ore, according to which the attitude and extension of lead-zinc ore body is inferred. Based on the analysis of known ore，s geology and ATEM anomaly characteristics, two prospecting target areas are delineated in the study area. The application effect of ATEM is remarkable in this area, therefore, implying this method can be applied to prospecting lead-zinc polymetallic ore associated with low-resistance bodies on a greater scale. |
