| 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 铜井式。归来庄式金矿的放地质审中生代浅成偏碱性侵入岩；泰山式金 的致矿地质异常是元古宙韧性剪切带；铜井式金矿的放地质异常是中生代浅成钙碱性侵入岩。

| Abstract: | 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. |
