构造地质

研究区正置ＮＥ向牟平──即墨断裂带上，褶皱复杂，断裂十分发育。ＮＥ向深断裂控制了区内４个花岗岩体分布；ＮＥ向及Ｅ—Ｗ向深断裂控制了中生代盆地展布。胶东群变质岩，元古代重熔花岗岩及交代花岗岩内的ＮＮ向、ＮＮＥ向相关剪切带中发育的蚀变糜棱岩化花岗岩带或断裂空间，是蚀变岩型金矿化及石英脉型金—银矿化的定位空间。Ｅ—Ｗ向深断裂旁侧的产于Ｋ１Ｌ１含炭岩系中先挤压后扭张的构造空间是新类型金矿产出空间。

GEOLOGICAL STRUCTURE

The researched region lies in Muping-Ji Me fault zone (NE strike),its fold is complex,its fracture is quite developed.The deep fractures of NE strike control the distribution of four granite bodies in the region; the deep fractureS of NE strike and EW strike control basin's distribution of Mesozoic Era.Altered mylonite granite zone or fault iS developed in the shear zone of NE and NNE directions in metamorphic rock of Jiao Dong group. Anatexis granite of Proterozoic Era and metasomatism granite is a position fixing space of gold mineralization of altered type and gold-silver mineralization of quartz vein'In K,L, Carbonaceous elastic rock, early stress-late shear tension structural poSition near the deep fracture of EW direction is appearing place of a new type of gold deposits.
