中文摘要:
      [摘 要]金翅岭金矿位于胶东西北部招远—莱州的中部,为石英脉型金矿。基于构造填图和古构造应力场反演,初步查明了该矿床控矿断裂的运动学特征和构造演化历史。研究表明:在侏罗系—白垩系时期,该矿床控矿断裂大致经历三期活动:成矿前构造应力场为NW-SE向挤压,成矿期为NE-SW向挤压,成矿后为NW-SE向挤压;成矿作用发生在构造应力场从NW-SE挤压到NE-SW向挤压转换时期。正是由于构造应力场转化使得控矿断裂开启,才导致成矿作用的发生。
英文摘要:
      Abstract: The Jinchiling quartz-vein type gold deposit is located in the central part of the Zhaoyuan-Lizhou metallogenic belt. Structural mapping and paleo-tectonic stress inversion reveal the tectonic movement features and tectonic evolution history of the Jinchiling gold deposit. The result shows that during the Jurassic to the Cretaceous period,the ore-control fault of this deposit underwent three stages of activities: (1) nearly NW-SW-directed compression stress before mineralization; (2) during mineralization, the stress field changed into NE-SW compression; and (3) the stress field converted to NW-SE compression again after mineralization. Mineralization occurred in the transformation period of the tectonic stress field. The mineralization occurred when the tectonic stress field transformed as aforementioned,which opened the ore-control fault and led to filling of ore bodies.
