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 aswell as themagnetic parametersmeasurement of dif2
ferent rocks, the aeromagnetic anomalies in J iangdong survey area were further interp reted, and it is concluded that themagnetic 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 regionalmetamor2
phic rocks of the Gaoligongshan Group. The exp loration criteria and potentialmetalmineralization styles of the region are also summarized in the paper |
