| 中文摘要: |
| 纳米比亚奥姆博姆博地区ΔT航磁化极异常以正异常为主,反映了朝斯组的分布范围。磁铁矿露头是找矿直接标志,一般分布在磁异常梯度带上。朝斯组高磁异常带是寻找磁铁矿床的优选目标靶区。通过野外地质调查及钻井揭露,在高磁异常带上发现了较好的磁铁矿体,预测该地区具有较大磁铁矿勘探潜力。 |
| 英文摘要: |
| ΔT aeromagnetic anomaly of reducting to the pole of Ombombo area of Namibia is dominated by positive anomly that basically reflects distribution extent of Nch formation.. Iron ore outcrops are direct mark for iron ore prospectring and generally distributed in gradient of the magnetic anomalies zone. High magnetic anomaly zone is the preferred target for magnetite deposit in Nch formation. Through field geological survey and drilling better magnetite ore bodies are discovered and the area is predicted potential for magnetite ore prospecting. |
