| 中文摘要: |
| 小池沟金矿区位于华北地台南缘熊耳山变质核杂岩构造下拆离盘新太古代太华变质核内,为燕山晚期熊耳山钼金银铅锌矿集区内的一个中型规模的薄脉型金矿床。该矿床产出于七里坪—星星印北东向区域性断裂北东端西侧,金矿体主要赋存于陡倾斜北北东向和北东向容矿断裂破碎带内,组成东、中、西3个脉群。脉状矿体主要产出于容矿断裂中央地段、发生共轭结点地段、局部弯曲地段、派生次级断裂出现地段。在空间分布上具有明显的侧伏性、等距性和雁列性。 |
| 英文摘要: |
| Xiaochigou gold deposit is located in the Neo-Archean Taihua Group, the footwall of detachment fault on the Xiong’ershan metamorphic core complex in the southern edge of North China Platform. The gold deposit is a medium-sized and thin vein-type gold deposit in the Xiong’ershan Mo-Au-Ag-Pb-Zn mineralization cluster field formed in the late Yanshanian period. This deposit is located in the western side of the northeastern end of regional NE-trending Qiliping-Xingxingyin fault, and the gold orebodies are distributed in the steep NNE-trending and NE-trending fracturing zones, and three vein groups are classified as the eastern, central and western vein group. The vein-type gold mineralization mainly occur in the central part of the ore-controlling faults, conjunction part, locally bending part, and the secondary fractures derived from the main ore-bearing faults. The gold orebodies has lateral plunging, isometric array, and en echelon in the spatial distribution. |
