| 中文摘要: |
| 豫西宅延M-158航磁异常历经多次查证,找矿均未取得实质性进展。本文从航磁异常、地磁异常、重力异常、激电异常特征及该区最新地质成果等方面对前人工作成果进行分析总结,结合邻近老里湾、中河大型银矿区找矿成果,认为宅延磁异常可能为银、铅、锌及铁磁性矿物等多金属矿引起的综合异常,圈出了2处铅锌找矿靶区,为该区最终取得找矿突破提供了必要的地质地球物理依据。 |
| 英文摘要: |
| The M-158 aeromagnetic anomalies to verify it with many times in Zhaiyan of Western Henan, no substantial progress has been made in prospecting. From the aeromagnetic anomalies of geomagnetic anomalies IP anomaly characteristics of the gravity anomaly and the latest geological achievements of predecessors' work is analyzed, combined with the Zhonghe and Laoliwan prospecting results in large silver mining area, think curtilage continuation of magnetic anomaly can be silver lead zinc and ferromagnetic minerals polymetallic caused by comprehensive anomaly, and circle the further exploration target areas, for the final prospecting breakthrough provides the necessary geological and geophysical basis and firm confidence. |
