| 中文摘要: |
| 坦桑尼亚北部维多利亚湖地区的太古宙克拉通苏库玛兰德绿岩带是寻找金矿的热门成矿带，研究区所在的卢马加沙(Rwamagaza)绿岩带位于苏库玛兰德绿岩带的西部，本文通过开展地面高精度磁法测量、激电中梯测量和激电测深测量相结合的综合物探方法研究，分析了物探异常特征，总结其规律并以此来探讨该地区寻找构造蚀变岩型金矿的综合物探勘查技术方法。经工程查证，在物探异常区内发现了金矿体，得出综合物探方法在该地区具有一定的找矿效果。 |
| 英文摘要: |
| The Archean craton Sukumaland greenstone belt in the Lake Victoria region of northern Tanzania isa popular mineralization belt for searching for gold deposits. The Rwamagaza greenstone belt, where the researcharea is located in the western part of the Sukumaland greenstone belt. Through a comprehensive geophysical explo-ration method combining high-precision ground magnetic measurement, induced polarization gradient measure-ment, and induced polarization depth measurement, the characteristics of geophysical anomalies were analyzed, andthe rules were summarized to explore the comprehensive geophysical exploration techniques for searching for struc-tural altered rock type gold deposits in the region. Through engineering verification, the gold ore body has been dis-covered in the geophysical anomaly area, and comprehensive geophysical methods have a certain prospecting effectin the region. |
