摘　　要：黄埠岭金矿7号脉属于石英脉金矿,是该矿区最主要的工业矿脉之一。研究表明,7号脉是由7-1、7-2号2个倾向SE和7-3号倾向NW的矿脉所组成的复脉,受F7构造带控制。矿体产于矿脉内,成矿分为4个阶段,矿化类型属于石英脉型。流体包裹体温度和压力研究结果表明,7号脉为中温中深成金矿。该矿脉内金矿化富集受构造、蚀变岩、矿化阶段、矿物组合和脉岩等多种机理控制,对该矿脉的深边部成矿找矿具有指导意义。No.7 vein of Huangpuling gold deposit belongs to quartz vein type gold mine,it is one of the most impor-tant industrial veins of this mine.Research shows,No.7 vein is a complex veins consist of SE orientation 7-1、7-2 and NW orientation 7-3,controlled by F7 tectonic belt.Ore bodies originates in veins,ore-forming divides into four stages.The mineralization types belongs to quartz vein type.The research of temperature and pressure of fluid inclu-sions shows,No.7 vein is mid-temperature and mid-depth gold mine.The gold mineralization enrichment of this mine is controlled by tectonic,altered rocks,mineralization stage,mineral association and vein rocks.It has guide sig-nificance for ore-forming and prospecting in deep and edge department of this vein.
