摘要
基于对易门凤山铜矿床综合研究,表明矿床明显受断裂控制。根据断裂力学性质,划分出三种构造体系,分别为SN向构造、EW向构造和NE-SW向构造,依次控制了矿床的总体展布、矿化的局部富集规模和矿体的形态产状。矿体赋存于主断裂旁侧发育的次级断裂、断裂之间的破碎带内或其裂面一侧的碎裂白云岩中,具有南北成带,NW成群,NE为脉状分部等特征均是找矿构造标志。
Comprehensive study of a large number of field data for the Fengshan copper deposit of Yimen shows that the deposit is obviously controlled by fracture zone.Three tectonic systems can be marked out according to the dynamic properties of the structure,including SN trend structure,EW and NE-SW trending structure,which controlled the general distribution of the deposits,enrichment scale of mineralization in part and orebody shape and occurrence.The ore bodies occur in the secondary faults and fractures within the fracture zone between the crash surfaces,or fragmentation dolomite on the sides of the main fractures.With the characteristics of SN trend belt formation;clustered in NW trend and veins occurring in NE-strike all being ore prospecting structure indicators.
