摘要
山东省海阳市郭城地区位于胶东地块的东部、胶莱盆地的北侧 ,发育着一系列与低角度拆离断层有关的金矿床。按其产出位置 ,可以分为产在拆离断层中的金矿化 (以土堆金矿为代表 )和拆离断层上盘反向断裂裂隙系统中的金矿化 (以沙旺金矿床为代表 )。通过研究这两类代表性金矿床的地质和地球化学特征 ,探讨了胶莱盆地东北缘与低角度拆离断层有关的金矿成矿作用。
A series of golden deposits associated with lower angle detachment faults widely developed in the northeast of Jiaolai basin, Guocheng region, Haiyang County, Shandong Province. According to their occurrence position, these deposits could be devided into two types, Tudui deposit and Shawang deposit which were the representatives respectively.Geological characteristics of these two deposits have been studied in detail, one genesis model has been proposed.
