摘要
元素地球化学异常分析对矿体原生晕具有较好的指示意义,因此,元素地球化学分析结合地质背景资料及地球物理探测等方法的多学科综合找矿方法是隐伏矿勘察的必要手段。珠琳镇地区元素地球化学异常水平分带显示元素成矿温度以大拖枯为热中心向外逐级递减,因子分析结果F_1因子为Bi,Pb,Fe_2O_3,Sn,Th元素组合,推断在旋转因子F_1得分高值区存在大拖枯隐伏岩体,而这一结论得到剩余重力异常资料验证。滇东南地区重要矿源层坡脚组(D_1p)与坡松冲组(D_1ps)在此出露,加之区内弧形构造普遍发育,为区内隐伏岩体及与岩体有关的铅锌银隐伏矿的存在提供依据。
Elemental geochemical analysis is a good method for prospecting by primary halos.A multidisciplinary comprehensive prospecting method which including the analysis of element geochemistry,in combination with the geological background and geophysical exploration methods is necessary for concealed ore prospecting.According to horizontal zoning of elemental geochemical anomaly,temperature of mineralization shows reducing from Datuoku heat center outward to edge in Zhulin area gradually.Factor F_1 from results of factor analysis stand for elements combination of Bi,Pb,Fe_2 O_3,Sn,Th,that inference a concealed rock mass in high value score area of rotate factor F_1,which has been proved by analysis on residual gravity anomaly.In addition,group(D_1p)and(D_1ps)which regard as important ore source bed in Southeast of Yunnan expose in research area,and arcuate structures of occur in Zhulin area universally,which was given evidence for existence of the concealed rock mass and related concealed ore deposits.
