摘要
琅琊山铜矿床包括两种成因类型的矿体,即层控矽卡岩型和接触带型矿体,并以层控矽卡岩型铜矿体为主。各勘探线剖面上面金属量的变化趋势分析表明,在垂直层控矽卡岩型铜矿体走向的截面上,若矿石平均品位高,则总矿化面积小,反之亦然,即总体矿化强度大致相等,据此可指出成矿过程中流体输运方向。将构造地质学分析与物理化学流体动力学分析有机结合,预测出琅琊山铜矿床的隐伏矿体,并获得CSAMT法验证。
The Langyashan copper deposit is composed of two kinds of copper orebodies, strata bound skarn one and contact-metasomatic skarn ore. In the cross sections vertical to trend of orebodies, the average Cu tenor of the strata bound orebodies is inversely proportional to the total mineralized area. The total minerallizing intensity in every section is generally equal. This principle can correctly indicate the direction of the fluid migration during the minerallizing processes. The concealed orebodies in the Langyashan copper mine have been calculated, with the tectonical geology combined with physico chemical hydrodynamics. Testified by CSAMT method, this successful predication of concealed orebodies is attributed to analysis of physico-chemical hydrodynamics.
