摘　　要：金厂沟梁金矿床39号脉为总体走向近南北、向西凸出的弧形矿脉,Au在弧形矿脉的两翼更为富集。As、Sb、Hg、F为前缘元素,Mo、Co为尾晕元素。前缘、尾晕元素以及由这些指示元素构成的因子得分和累加指数等是矿脉含矿性预测的有效的地球化学标志。根据地球化学预测标志,预测39号脉在南翼十五中段以下和北翼十三中段以下还有矿体存在。矿脉在深部铜矿化增强,推测金厂沟梁向深部可能转变为金铜矿床。No. 39 gold lode in the Jinchanggouliang gold deposit occurs as an arc of SN trending that is convex to west and is richer at its two segments. In the vein, As, Sb, Hg and F belong to front halo elements, and Mo and Co to tear halo elements. These front and rear elements, their factor scores and their additive index make up the valid geochemical indictors for the prediction of the blind ore bodies in the vein. These geochemical indicators reveal that some blind ores bodies probably be found under 15^th level at the southern portion of the lode and under 13^th level at the northern. Cu content apparently increases at the lower levels of the deposit and it is quite possible that the deep part of the deposits could be changed into a Au - Cu deposit.
