山东焦家金矿新、老Ⅲ号脉数学地质分析

The Geomathematic Analysis on The New and Old Ⅲ Vein of Jiaojia Gold Deposit in Shandong Provinnce

在野外地质工作基础上,对焦家金矿新、老Ⅲ号脉不同标高所采样品进行微量元素分析,并利用数学地质方法,对微量元素空间变化规律、相关性关系及原生晕特征进行了分析。对成矿-成晕过程中指示元素在蚀变带内的带入带出特点进行了归纳总结;确定了新、老Ⅲ号脉Au元素所在的F1主因子分别为Bi、Ag、Sb、Pb、Hg、Cu、Au和Bi、Ag、Au、Pb,代表着热液作用过程中Au的主成矿期。同时,对新、老Ⅲ号脉深部成矿远景进行了预测。

On the basis of field geological work, using mathematic geology method, the paper carries through the analysis on the varying law, relationship of trace elements and the primary halo feature in different elevation of the new and old Ⅲ vein. And then summarize the alteration law of the indicator element in the metallization process. Determine the F1 main factors of Au in the two Ⅲ vein are respectively Bi、Ag、Sb、Pb、Hg、Cu、Au and Bi、Ag、Au、Pb, which reveal the dominant mineralization period of Au in the hydrothermal process. At the same time, the paper forecasts the deep mineralization feature of the two Ⅲ vein.
