| 摘 要： | 山东鲁西地区绿岩带地层总体金背景值较高，是金矿形成的矿源层。无论是保存相对完好的绿岩带还是被TYG改造后的花岗一绿岩带，均有利于金矿形成。已知金矿床的形成与分布均与韧性剪切带有关，韧性剪切带是形成绿岩型金矿的主要控矿构造。强烈韧性变形和破碎并富含绿岩带残留体的TYG岩系与金成矿关系密切。中生代燕山期岩浆热液活动的叠加有利于进一步富集成矿。 |

| Abstract: | With relatively high total gold background values, the strata of the greenstone belt in western Shandong are source beds of gold deposit. Both the well-preserved greenstone belt and TrG-reworked granite-greenstone belt are favorable for gold deposit formation. The formation and distribution of the known gold deposits are both related to ductile shear belts, which are major ore-controlling structure of greenstone type gold deposits. The TrG series, which have experienced strong ductile deformation and fragmentation and contain rich greenstone belt remnants, have close relation with gold deposit formation. Superimposition of Mesozoic Yanshanian magmatic-hydrothermal activities favorable for further gold concentration and mineralization. |
| Keywords: | greenstone belt ductile shear belt gold deposit deposit characteristics western Shandong |
