| 中文摘要: |
| 坦桑尼亚的Nykisirbri金矿床属于构造蚀变岩型金矿。在该区进行的传统电阻率法不同装置类型的试验性工作表明,构造带与背景岩石的电性差异明显,构造蚀变带和金矿体具有"低阻"特征,具有在背景岩石中寻找构造蚀变带的物探电性基础。运用视电阻率参数确定了构造蚀变带的延伸方向和规模;取得了矿脉群上的电性异常反映,从而进一步确定了金矿床的赋存空间和可能的产出位置,为钻孔的布置提供了依据。 |
| 英文摘要: |
| Nykisirbri gold deposit in Tanzania belongs to the altered cataclastic rock type gold deposit. Tests of traditional resistivity survey of varied equipments at the deposit show that electric property difference occur over fractural zone and the background rock and the altered cataclastic zone and gold ore body are characterized by low resistivity thus lay a foundation for targeting the altered cataclastic zone from the background rock. Apparent resistivity parameter method is applied to the deposit and successfully detects strike and size of the cataclastic zone and the electric property anomly over the ore vein groups collected and space where gold ore body occurs located so as to provide evidence for drill holes' layout. |
