摘　　要：旧店金矿床为山东省平度市重要金矿床之一 ,1号脉为该矿床主要矿脉 ,其矿化类型为含金石英脉型 ,成矿作用划分为 :Ⅰ黄铁矿 -石英 ,Ⅱ石英 -磁黄铁矿 -中粗粒黄铁矿 ,Ⅲ石英 -黄铁矿 -微细粒黄铁矿 ,Ⅳ石英 -多金属硫化物 -铁、锰碳酸盐及Ⅴ石英 -碳酸盐等 5个热液阶段 ,其中Ⅱ、Ⅲ、Ⅳ为金的主要富集成矿阶段。本文研究了 1号脉原生岩石地球化学特征 ,并根据元素垂向分带特点及因子分析结果 ,评价了该脉深部成矿远景 ,指出 6～ 8号矿体区段 - 30 0m标高以下地段仍有较好找矿前景。Jiudian gold deposit is one of important deposits in Pingdu County, Shangdong Province. Vein No.1 is the main production vein in the mining district, and is a gold-bearing quartz vein. The metallogenic process can be classified into five hydrothermal stages, Ⅰ pyrite-quartz, Ⅱ quartz-pyrrhotite-medium to coarse grained pyrite, Ⅲ quartz-pyrite-micro grained pyrite, Ⅳ quartz-polymetallic sulphide-Fe, Mg carbonate and V quartz-carbonate. Stages Ⅱ, Ⅲ and Ⅳ are the main ones for gold enrichment. This paper studied the primary petrochemical characters of vein No.1. On the basis of vertical elementary zonation features and factorial analysis result, the paper evaluated metallogenic perspective in vein No.1, and concluded that a better mineralization perspective can be expected in ore-body No.6～8 at depth beneath -300m.
