| 中文摘要: |
| Shoga金矿紧邻坦桑尼亚金矿富集区丘尼亚,具有良好的成矿条件和成矿地质背景。本文用野外观察描述和室内统计对比的方法,从展布特征、矿化蚀变、力学性质及断裂构造与石英脉和化探异常的关系等方面对矿区内NW向和NE向两组断裂构造进行了分析研究,得知NW向断裂为矿区的主要成矿断裂,其控制着矿区内含金石英脉和化学元素异常的分布。通过对矿区内共轭节理的统计分析得知区内NE、NW向断裂主要受来自矿区南西方向的应力作用而成。 |
| 英文摘要: |
| Shoga,a village of Tanzania Mbeya province, adjacent to Chunya which riched in gold, has good metallogenic conditions and geological background. Field describing,observing and statistical comparison methods are applied in this paper. The writer research the NW and NE fault from faults distribution characteristics, mineralization, alteration, mechanical properties and the relationship between faults and quartz veins, geochemical anomalies.The research result is that NW faults are the main mineralizing fractures in Shoga area, and they dominate the distribution of quartz veins and the chemical elements in this area. Also,the conjugate joints are researched by the writer in this area, he found that the tectonic stress which NW and NE faults are generated by come from the southwest. |
