胶东金成矿省位于胶辽隆起,中朝地台东部,基底岩石是太古宙和元古宙变质岩。中生代沉积及火山盖层产于拉伸盆地中,侵入岩主要是中生代花岗岩类,基底杂岩中有东西向复背斜及大规模的中生代北东—南西向和北北东—南南西向的断裂带。金矿化与花岗岩中或花岗岩与基底岩石接触带中的中生代断层及其派生断层有关。矿化类型是石英脉型和蚀变岩型。围岩蚀变在矿带周围非常发育。蚀变矿物有石英,绢云母(和铬云母)、黄铁矿、方解石、绿泥石、赤铁矿、金红石、石墨。在所有的矿床中,矿石的矿物组合都是一致的。矿物组合包括:黄铁矿、黄铜矿、闪锌矿、毒砂、方铅矿、自然金、银金矿、磁黄铁矿、碲银矿、砷金银矿等等。华南和华北陆块在中生代碰撞和俯冲、造成了中生代花岗岩体的侵入。花岗岩浆来自地壳部分熔融。金从基底岩石中活化迁移,并且通过与这些作用有关的高温热液沉积在断裂带中。
Jiaodong gold mineralization province is located in the Jiaoliao uplift, the eastern part of the platform, the basement rocks are Archean and Proterozoic metamorphic rocks. The Mesozoic sediments and volcanic caprocks are produced in the extensional basins. The intrusive rocks are mainly Mesozoic granitoids. The basal complexes have east-west anticlines and large-scale Mesozoic Mesozoic north-south and north-north east-south-south-west faults band. Gold mineralization is associated with the Mesozoic faults and their associated faults in the contact zones of granites and granites with basement rocks. Mineralization types are quartz vein type and altered rock type. Wall rock alteration is very developed around the ore zone. Alterated minerals are quartz, sericite (and chrome mica), pyrite, calcite, chlorite, hematite, rutile, graphite. In all the deposits, the mineral assemblage of the ore is the same. The mineral assemblages include: pyrite, chalcopyrite, sphalerite, arsenopyrite, galena, natural gold, silver and gold, pyrrhotite, silver telluride, arsenic, gold and silver and many more. The South China and North China terranes collided and subducted during the Mesozoic, resulting in the intrusion of Mesozoic granite bodies. Granite magma from the crust partially melted. Gold is activated and migrates from the basement rock and is deposited in the fault zone by the high-temperature hydrothermal fluids associated with these effects.
