| 摘 要： | 笔者结合1/5万磁法扫面及相关磁参数测定工作,在路线地质调查的基础上,进一步对引起江东测区航磁异常的原因进行了客观的分析和总结,得出该区磁异常并非某些专家所讲由"似条带状含铁硅质岩建造(铁多金属矿化)"引起,而实由高黎贡山群中-高级区域变质岩类产生的结论,并对在该区进行地质勘查的找矿标志、矿床类型等找矿方向提出了自己的观点.

| Abstract: | Based on field geological traverses and 500m line-spacing ground magnetic survey as well as the magnetic parameters measurement of different rocks,the aeromagnetic anomalies in Jiangdong survey area were further interpreted,and it is concluded that the magnetic anomalies in the area are not resulted from so-called 'banded iron formation' inferred by some experts,the anomalies are very likely sourced by the high-grade regional metamorphic rocks of the Gaoligongshan Group.The exploration criteria and potentia... |
