摘　　要：河南省神硐沟锰银矿位处华北地台南缘,主要出露熊耳群火山岩和官道口群碳酸盐岩等。矿区单斜构造,断裂发育,近东西向断裂F1为主要含控矿构造。神硐沟-后阴锰银矿体赋存于高山河组石英砂岩与龙家园组燧石条带白云岩层间的F1断裂构造剥离带中。矿体顺层产出,倾角平缓,形态受构造控制,属岩浆后期热液作用形成。采冶遗迹、含矿构造、围岩岩性、蚀变矿物等找矿标志明显。Shendonggou manganese-silver deposit is located on the southern margin of the North China platform,and it mainly exposes Xiong’er Group volcanic rock and Guandaokou Group carbonate rock.The mining area has a monoclinic structure with developed faults,and the near-west fault F1 is mainly containing ore-controlling structures.Shendonggou-Houyin manganese-silver ore body occurs in F1 fault-structure-stripping zone between the quartz sandstone of Gaoshanhe Formation and the dolomite belt of Longjiayuan Formation.The ore body is produced in layers,the dip angle is gentle,the shape is controlled by the structure,and it is formed by the hydrothermal effect in the late magma.Prospecting signs such as mining ruins,ore-bearing structures,lithology of surrounding rocks,altered minerals,etc.are obvious.
