易门铜矿三家厂矿田成矿元素特征分析

Analysis on the Characteristics of Minerogenetic Elements of Sanjiachang Orearea,Yimeng Copper Mine,Yunnan

通过系统的归纳和总结矿田中各层位、矿化蚀变和矿体多元素地球化学特征,建立了成矿元素迁移、成矿、元素轴向分带序列等多元素组合关系.利用统计规律并结合地质现象,对成矿元素进行合理解释,确定了指示元素组合标志和盲矿预测靶区,奠定了三家厂矿田盲矿预测的地球化学基础.

Based on systematic Conclusion and the summing up of the charasteristics of elements gelchemistry on layers,country rock alteration,and orebodies in Sanjiachang Orearea,the auther has set up elements assernblage relations on the removal of minerogenetic elements,mineralzation,axial zonality seguence of primary dispersion halos,etc.Making full use of statistical laws and integrated with geological phenome- non,the author has rasonably explained minerogenetic elements,defined making of indicatorelements as- sociation and shooting range of blindore prognosis,and established the elements geochemistry basis of blindore prognosis for Sanjiachang Qrerea.
