摘要
介绍了焦家金矿床岩石地球物理及微量元素地球化学异常特征。矿区岩石的电阻率随岩石破碎程度增加而明显降低，随（矿化岩石）硅化程度增强而升高，电磁高极化率异常与主含矿构造（主矿体）的高硫化物含量带相吻合的这些特征，可用于预测深部盲矿体。研究了矿床微量元素的分布和富集特征及原生地球化学异常分带，建立了矿床地球化学异常模式及评价指标。
The abnormal characteristics of geophysics of rock and geochemistry of trace elements of Jiaojia gold deposit are introduced.The electric resistivity of rock in mineral region lowers markedly along with the increasing of the extent of rick’s breaking while it heightens along with the enhancing of the extent of silication of mineralizing rocks.Besides,the abnormality of high polarizability of electric magnet is coincide with high sulfide content zone of main orebody.The above characteristics can be used to prognosticate deep blind orebody.The characteristics of the distribution and concentration of trace elements of the deposit and the abnormal zoning of primary geochemistry are also studied.The abnormal pattern of geochemistry of the deposit and evaluation index are established
