| 摘 要： | 在胶莱盆地及其周边部位, 已发现许多金矿床(点), 典型矿化类型主要有: 受滑脱拆离断层控制的中温热液交代蚀变岩型金矿(乳山蓬家夼)、受构造控制的中温热液充填交代蚀变砾岩型金矿(牟平发云夼)、中温热液改造型金矿(平度大庄子)、次火山岩型金矿( 五莲七宝山)。对比分析各矿床地质特征、成因以及演化历史, 认为这些矿床是在不同构造位置、不同成矿流体参与下形成的不同类型的金矿床。以期推进胶莱盆地及周边金矿的研究、指导进一步的找矿工作。

| Abstract: | Many gold deposits have been discovered in Jiao-Lai basin and its periphery.Thema in type of discovered deposits as follows:middle temperature hydrothermalme tasomatic alternation rock type gold deposit controlled by slid dismantled fault (Pengjiakuang in Rushan),middle temperature hydrothermalmetasomatic filled alternation gravel-stone type gold deposit controlled by tectonics (Fayunkuang in Muping),middle temperature hydrothermal-reformed type gold deposit(Dazhuangzi in Pingdu),subvolcanic rock type gold deposit(Qibaoshan in Wulian).Their geneses are discussed.Analyzing their ore geological characteristics,deposit types and genesis,evolving history,we find that they are both similarities and differences,in different tectoniclocation,different ore-forming fluid add in to form different types of gold deposits.On this bases,we hope that it can promote the research of the deposits in Jiao-Lai basin and its periphery,and direct farther prospecting derection. |
