摘　　要：山城金矿为石英脉型金矿，受断裂构造控制。本文以多种地质、地球化学信息为基础，讨论该矿元素组合及其时空分布。结果表明，元素组合与一定成矿阶段和构造空间对应，并有一定载体，其中第一阶段元素组合与构造面倾角变化有关，栽体主要为石英脉，主成矿阶段元素组合与构造面走向扭动有关，载体主要为多金属矿化，进而查明了各阶段指示元素和矿体延伸方向。同时讨论了元素指示意义的局限性。Shancheng gold ore deposit is a fault controlled quartz-vein type gold ore deposit in Shandong province. The element associations and their spatial temporal distribution are discussed based on synthetic analyses of multiple geological and geochemical information. It is shown that the element associations are in correspondance with some mineralization stages and structural positions. The Pb-Ba association is related to the first stage of quartz vein and spatially the variation of dip angles of the fault surfaces. Both the Au-Ag-Cu and As-Sb-Hg associations are related to the main mineralization stage and the variation of strikces of the fault surfaces, indicating horizontal shearing. The indicator elements, their limitations and the plunging and extension of the ore bodies are further discussed. It is proposed that the indicator element associations are indicative only when considering the related mineralization stages.
