摘　　要：归来庄金矿的发现为鲁西地区金矿勘探提供了重要线索,其所在的鲁西铜石杂岩体外围多年来金矿不断突破,随着金矿勘探的进一步需求,为探索其外围找矿前景,本文在成矿地质背景基础上,对研究区进行物探、化探异常查证工作,研究表明研究区Au、Ag异常值较高,伴生元素多为高温热液成矿元素组合,主要分布在研究区断层及断裂带交汇部位,特别是频繁的岩浆活动为金矿的运移和富集创造了条件,为该区金矿勘探指明了方向。The discovery of the Guilaizhuang gold deposit provides an important clue for gold exploration in Western Shandong,where the periphery of the Tongshi complex witnesses many times of breaking through in prospecting in recent years. To meet the further demand of gold exploration at this place,to explore the prospecting prospects of its periphery,on the basis of metallogenic geological background,this work carries out verification to geophysical and geochemical anomalies in this area. Results show that the abnormal values of Au and Ag are relatively higher in the study area. The associated elements are mostly high temperature hydrothermal mineralization elements,which are mainly distributed at the intersection of faults and fault zones. In particular,frequent magmatic activities have created conditions for the migration and enrichment of gold deposits and point out the direction for gold exploration in this area.
