摘　　要：根据鲁西金矿的地质特征，划分为3种成因类型：归来庄式、泰山式和铜井式.归来庄式金矿的致矿地质异常是中生代浅成偏碱性侵入岩；泰山式金矿的致矿地质异常是元古宙韧性剪切带；铜井式金矿的致矿地质异常是中生代浅成钙碱性侵入岩.3类金矿的时空分布表明，鲁西地质历史中金的成矿作用具有继承性和新生性.泰山式金矿或元古宙含金韧性剪切带是归来庄式和铜井式金矿的背景地质异常．The gold deposits in the western Shandong Province can be classified as three genetic types:Guilaizhuang type, Taishan type and Tongjing type. The ore-generating geological anomaly in the Guilaizhuang-type gold deposits is determined to be the Mesozoic shallow meta-alkaline intrusive rocks, that in the Taishan-type to be the Proterozoic ductile-shearing zones and that in the Tongjing type to be the Mesozoic shallow calc-alkalic intrusive rocks. The space-time distributions of the three types of gold deposits demonstrate that the gold mineralization in the geological history, western Shandong Province is characterized by the succession and neogenesis. In this sense, the Taishan-type gold deposits or the Proterozoic ductile- shearing zones are defined to be the background geological anomalies for the Guilaizhuang and Tongjing types of gold deposits.
