摘　　要：嵩县前河金矿北部一带金矿区位于华北克拉通南缘的熊耳山地区,金矿赋存于熊耳群,容矿岩石为构造蚀变岩,断裂构造与合峪岩体控制着金矿的产出。围岩蚀变中硅化、黄铁绢英岩化、黄铁矿化和多金属矿化与金成矿关系密切。矿床地质特征与前河金矿类似。研究表明:矿床类型为低温热液蚀变岩型矿。最后总结了找矿标志,研究认为矿床深部仍然具有较大找矿潜力。The northern mining area of Qianhe gold deposit in Songxian County is located in the Xiong'ershan area on the south margin of the North China Craton.The gold deposits are hosted in Xiong'er Group,and the hosted rocks are the structural altered rocks.The occurrence of gold deposits is controlled by the fault structure and Heyu rock mass.In the surrounding rock alteration,silicification,pyrite sericinization,pyrite mineralization and polymetallic mineralization are closely related to the gold mineralization.The geological characteristics of the deposit are similar to that of Qianhe gold deposit.The research shows that the deposit type is low-temperature hydrothermal altered rock type.Finally,the prospecting marks are summarized.The research indicates that there is still a great prospecting potential in the deep part of the deposit.
