摘要
长城金矿属于构造裂隙充填型热液矿床,虽然各矿脉在地表的走向大体与呈NW-NWW走向的围岩长城系、蓟县系产状相近,但金矿化的范围和强度却呈近SN或NNE向,否定了该矿床的矿化和分布受长城系和蓟县系地层控制及属层控卡林型金矿床的见解,认为金矿化主要受深部隐伏的近SN-NNE向主干断裂构造控制,找矿工作应按照这一认识和规律进行部署,并把重点放在寻找隐伏的主干成矿构造及其相关的矿床、矿体上。
Changcheng-type gold deposit belongs to the structure fissure filled hydrothermal deposit,the surface trend of ore vein is similar to NW-NNE trend of wallrock Changcheng and Lixian system, but the scope and intensity of gold mineralization near to SN or NNE trend, this deny that the mineralization and distribution of Changcheng-type gold deposit are controlled by strata of Changcheng and Jixian system. The research realizes that gold mineralization is controlled by the depth of concealed SN-NNE main fault structure, and prospecting work should be deployed according to this conception and regularity, focus on search the deeply concealed metallogenic structure and related mineral deposit and ore body.
