摘　　要：本文总结了铁砂街矿田火麻坞银多金属矿区成矿地质背景、矿体地质特征、矿石特征,认为矿体主要赋存铁砂街岩组中段第三亚段变石英角斑岩层内普遍存在千糜岩和糜棱岩化及千糜岩化泥质碳酸盐岩断裂破碎带中,位于东西向萍乡—广丰深断裂带中段的铁砂街构造带内。受F3断层控制,成矿与晋宁期海底火山喷发沉积形成的巨厚层状细碧角斑岩系密切相关。同时指出矿区今后找矿方向,认为主断层F3深边部找矿潜力大。This paper summarizes the iron ore field fire ma dock street silver polymetallic mining area of ore-forming geological background,geological characteristics of ore bodies,ore characteristics,orebody occurrence mainly iron ore rock group of middle period of the first sanya street variable Angle of quartz spot within the strata are widespread qian mi rock and mylonitization and qian mi lithification argillaceous carbonate fractured zone,located in the east-west pingxiang--GuangFeng deep fault belt tectonic belt in iron ore in the central part of the street.Under the control of F3 fault,the mineralization is closely related to the superthick stratiform porphyry system formed by submarine volcanic eruption and deposition during The Jinning period.At the same time,the direction of prospecting in the future is pointed out,and it is considered that the deep edge of main fault F3 has great potential for prospecting.
