摘　　要：党河南山地区产出有众多的金及多金属矿床(点),这些矿床(点)受近北西向区域性断裂的控制;同时近东西向构造带对本区成岩、成矿的控制作用明显。通过构造形迹、重磁特征、遥感影像、化探异常特征、水系特征、岩浆岩分布特征等方面的研究,确定本区近东西向构造带的存在。3条近东西向构造带控制了本区次级构造区,同时近东西向构造带与北西向区域断裂交汇处是本区矿产产出的主要部位,通过此规律的认识,在本区寻找到了东三湾金矿床和鸡叫沟金矿床。There occur many gold and polymetal ore deposits in Danghenanshan district, they are controlled by regional NW direction fracture. Meanwhile covered near EW direction structure belts control the diagenesis and mineralization obviously. Study on structure expression, feature of gravity and magnetic field, remote - sensing image, characteristic of geochemical exploration anomaly, feature of hydrographic net, distribution of magmatic rock revealed the covered near EW direction structure belts. 3 near EW direction structure belts controlled secondary structures in the district. The deposits occur mainly in the zone where covered near EW direction structure belt and NW direction regional fracture converge. As a result, Dongsangou gold deposit and Jijiaogou gold deposit were discovered in the district.
