河南公峪金矿区断裂控矿作用分析

公峪金矿区以构造蚀变岩型金矿为主，已发现含金矿脉２０ 余条，预测远景储量５０ｔ 以上，找矿前景良好。根据构造控矿的观点，从区域构造应力场转换入手，分析了区域构造演化与成矿作用的关系，对矿区内断裂控矿作用进行了论述，指出正是由于控矿断裂的规律性活动，导致了工业矿体具有等间距性、侧列性及侧伏性等分布规律，控矿断裂的规模及演化控制了矿体的规模及演化；阐述了构造活动与矿体定位的关系

CONTROL OF FAULTS ON METALLIZATION IN THE GONGYU GOLD MINE, HENAN

In the Gongyu gold deposit features, orebodies are hosted in the altered fracturing zones. Over 20 gold lodes have been discovered. The reserves are forecasted to be over 50 ton. According to transformation of regional stress and the relation between tectonic evolution and mineralization, the structural control on metallization is discussed. The regularities of ore-controlling structures are responsible for the distribution of orebodies in equal distance, lateral deployment and lateral plunging. The scale and development of ore-controlling faults control the scale of orebodies and evolution of metallization. The relations between structural activity and location of orebodies are inquired into.
