| 中文摘要: |
| 坦桑尼亚基戈马卡万加地区地处热带高原地球化学景观区，地质工作基础薄弱，选择适当范围进行1：50 000土壤测量，从中筛选较好的异常作为工作靶区，进而开展1：10 000土壤测量，得到了形态基本完整，不同元素叠加有序的Cu-Pb-Zn组合异常，经过地质检查和槽探工程验证，在产状稳定的泥质页岩中见到孔雀石化，并有NNE向断裂控制异常的产出，金属矿化受地层和断裂的共同控制，具有进一步工作的价值。 |
| 英文摘要: |
| Kavanga area of Kigoma in Tanzania is located in tropic geochemical landscape area with poor geological survey. In certain extent soil geochemical survey is carried out at scale 1:50 000 then optimum anomlies are screen out to be working areas for soil geochemical survey at scale 1:10 000 and integrated Cu-Pb-Zn anolies with good morphology and sequential elements overprinting are lineated. The integrated anomlies are checked with field survey and trenching. Malachite is discovered in muddy shale with stable attitude and the anolies are controlled by NNE faults. The metal mineralization is controlled by both of the stratum and faults thus the area is payable for further exploration. |
