| 中文摘要: |
| 来阳沟金铁矿区地处华北地台北缘重要金矿集中区，金矿床为石英脉型和构造蚀变岩型，矿体赋存在闪 长岩及混合岩内，受断裂控矿明显。为了指导深部及外围找矿，本文通过对区域地质背景、矿区地质特 征、矿体特征、地球物理特征等方面阐述，总结了成矿规律及找矿方向。分析认为本区金矿床是与区域混 合岩化热液作用及构造运动低温热液活动有关的石英脉型及构造蚀变岩型金矿床，与硅化、黄铁矿化、方 铅矿化、闪锌矿化、黄铜矿化等关系最密切；矿区内北东向、北西向构造为矿区主要的容矿构造，金矿(化) 体呈脉状、透镜状产出，沿构造破碎带断续分布；区内 6条含矿构造带内构造复杂，与地球物理异常吻合， 成矿条件优越，找矿潜力巨大，可为下一步找矿工作提供一定指导意义。 |

| Laiyanggou gold and iron ore area is located in the important gold ore concentration area of thenorthern margin of North China Platform, and the gold deposits are quartz vein type and tectonic alteration rocktype, and the ore body is deposited in diorite and mixed rock, which is obviously controlled by faulting. In order toguide the deep and peripheral prospecting, this paper summarizes the metallogenic law and prospecting direction by expounding the regional geological background, geological characteristics of the mining area, ore body characteris-tics, geophysical characteristics, etc. According to the analysis, the gold deposits in this area are quartz vein typeand tectonic alteration rock type gold deposits related to regional mixed lithification hydrothermal interaction andlow-temperature hydrothermal activity of tectonic movement, and are most closely related to silicification, pyritemineralization, galena mineralization, sphalerite mineralization, chalcopyrite mineralization, etc. The north-east-trending and north-west-trending structures in the mining area are the main ore-bearing structures in the miningarea, and the gold ore (chemical) body is vein-like and lens-like output, which is intermittently distributed alongthe structural fracture zone. The structure of the six ore-bearing structural belts in the area is complex, consistentwith geophysical anomalies, the metallogenic conditions are superior, and the prospecting potential is huge, whichcan provide certain guiding significance for the next prospecting work. |
