摘　　要：简单地介绍了金英金矿围岩、含矿岩层和矿区构造特征,矿石结构构造、矿物共生组合、矿物生成顺序、矿脉间的穿切包容关系,将矿床形成划分为4个矿化阶段,即早期硅化石英-金-烟灰色黄铁矿阶段;微细粒硅化石英-金-星散浸染状黄铁矿阶段;重晶石、玉髓-金-赤铁矿阶段和微含金细粒黄铁矿—白铁矿迭加矿化阶段。详细地论述了个成矿阶段每一成矿阶段具体特征。The paper introduced Jinying gold surrounding rocks,the ore-bearing rock formations and mining structural characteristics,ore texture and structure,mineral assemblages,mineral formatiom order,cutting across containment relationship in veins,the deposit can be divided into four metallogenic stages,namely early silicified quartz-gold-gray pyrite stage;micro-fine-grained silicified quartz-gold-scattered disseminated pyrite stage;barite,chalcedony-gold-hematite phase and micro-gold-bearing fine-grained pyrite-marcasite superimposed metallogenic stage.Discussed in detail the metallogenic stages of each of the specific characteristics of metallogenic stages.
