| 中文摘要: |
| 天宇铜镍矿床是东天山地区典型的铜镍硫化物矿床,位于中天山地块北缘,沙泉子深大断裂南侧,含矿岩体主要产于Σ20号杂岩体内。利用GSM-19T质子磁力仪,对天宇铜镍矿床开展高精度磁法测量。通过2.5维人机交互反演进一步验证了两个已知钻孔间铜镍矿体的空间赋存关系。分析Σ20号杂岩体和Σ19号杂岩体的磁异常特征,总结有利的赋矿部位,为在该区开展磁测工作提供参考。 |
| 英文摘要: |
| Tianyu Cu-Ni deposit is a typical Cu-Ni sulfide deposit, which is located in northern margin of Central Tianshan Block, south of the Shaquanzi deep fracture. Ore body is mainly hosted in the Σ20 complex rock. High-precision magnetic measurements were made on Tianyu Cu-Ni deposit by the GSM-19T proton magnetometer. The geometrical relationship of Cu-Ni body between two known drillholes has been further confirmed by 2.5D interactive inversion. This paper is to analyze the magnetic anomaly characteristics of Σ20 and Σ19 complex rocks, and find out where is suitable for the ore body existing in order to provide guidance magnetic survey in this region. |
