摘　　要：银山多金属矿田位于赣东北深断裂带之北西盘，矿田矿化分布具有典型的水平与垂直分带性特征，其主体构造是由浅变质岩系构成的北东向展在的“轴部构造”，包括银山背斜和一系列断裂构造带。它们是在东西向基底紧密褶皱群和挤压片理带的基础上发展起来的，矿田轴部构造控制了火成岩，特别是次火山岩的总体分布，同时也控制了矿化、蚀变的总体分布。矿田内新华夏系一对扭裂面，是控制矿脉的主要构造裂隙。Yinshan polymetallic ore field is located in the northwestern partof deep-fracture zone in northeast Jiangxi.The metallization distributionin the ore field is characterized by the typical horizontal and verticalzoning.Its major structure is the″axial structure″of NE-trending distri-bution composed of the epimetamorphic rock series, including Yinshananticline and a series of faulted zones.They are developed on the basisof tight bundle of fold and compressional schistosity zones in the EW-trending basement. The volcanic rock is controlled by the axial structure in the orefield,especially the total distribution of subvolcanic rock, and also thetotal distribution of metallization and alteration. A pair of shear fractu-ral plane of Neocathaysian system within the ore field is the major stru-ctural fissures controlling ore vein.
