摘要 潞西金矿位于三江构造转换带西南缘与印度地块———高黎贡山变质地体东缘过渡区的陇陵—瑞丽北北东向断裂带内,矿区赋矿地层与岩性主要为侏罗系泥质灰岩和二叠系泥硅质岩。在成矿规律研究的基础上,对矿区广岭坡、麦窝坝、勐莫矿段实施了γ能谱测量,通过各测区γ能谱测量总强度曲线及放射性测量结果统计特征值的分析,圈定了有利成矿地段,配合矿区其它地球化学勘查方法,取得了很好的找矿效果。 Luxi gold deposit is located in the NNE-trending Longling-Ruli fracture zone which situates in the transition zone between the southwest margin of the 'Three Rivers'(Lujiang River,Lancang River and Jingsha River) transforming zone and the eastern transiting area of India block-Mt.Gaoligong metamorphic terrain.The hosting sedimentary sequences in the ore zone are the muddy limestone of Jurassic age and muddy siliceous rocks of the Permian age.Based on the detailed research on metallogenic characteristics,the γ-ray energy spectrum survey was carried out in the Guanglingpo ore section,Maiwoba section and Mengmo ore section of the Luxi ore district,some mineralization-favorable targets was selected by the study on the features of the total γ-ray energy spectrum intensity in different sections and their statistic characteristics.Combined with other geochemical survey,some significant exploration discoveries were obtained.
