摘　　要：胶莱盆地是 Ｊ３ － Ｋ１ 期间由牟平—即墨断裂带在右旋走滑运动中形成的 Ｓ型拉分盆地，盆地的产生与盆地边缘金矿的形成具有密切的成因关系。在盆地的形成过程中，盆地基底和周边地区为金矿的形成提供了丰富的成矿物质；中生代的岩浆活动和火山活动则提供了成矿的热源和赋矿空间。通过对蓬家夼矿床的分析，认为胶莱盆地周边具有较好的成矿远景。Jiaolai Basin is a pull apart basin which was formed in the right lateral strike slip movements of Mouping Jimo faults during J 3-K 1.Some gold deposits were formed in the margins of the basin in that time.The ore bearing elements of these deposits were gived by the basement and the surrounding rocks of the basin,and the heat source and the host structure were formed by the magmatic and volcano activities in the Mesozoic.It is considered that the Jiaolai Basin has a huge prospective reserve.
