摘　　要：蚀变-流体地质填图是近年来用于了解流体系统和指导矿床勘查的重要方法。九瑞地区是中国重要的铜金铅锌矿集区。对九瑞矿集区开展系统的野外观测与综合研究,结果显示九瑞矿集区存在海西期喷流沉积流体系统、燕山期岩浆流体系统和燕山期中低温热流体系统。本文探讨了九瑞矿集区中-低温热流体的特征及其空间分布,同时也讨论了与其相关的矿化作用及矿化分布情况。与中-低温热流体相关的矿化作用主要发生在岩体外围与硅化断裂破碎带密切伴生的Au(Ag)矿化,以及叠加在海西期层状硫化物之上的层孔改造型Ag(Au)-Cu-Zn-Pb矿化,且在矿集区内小腊山、港南、邓家山、东雷湾、金鸡窝、白杨畈等多地均有发生。Alteration-fluid geological mapping is an investigation of the regional fluid geology,and also is a way to understand the hydrothermal fluid system and guide the mineral exploration.Jiujiang-Ruichang is a very important lead,zinc,copper,gold ore concentration area in China.It carried out field investigation and comprehensive study in Jiujiang-Ruichang.The study results show that,there are three fluid systems in Jiujiang-Ruichang,i.e.,Hercynian exhalative-sedimentary fluid system,Yanshanian magmatic fluid system and Yanshanian low temperature termal fluid system.This paper discusses the characteristics and spatial distribution of medium-low temperature thermal fluids in the Jiujiang-Ruichang ore concentration area,and also discusses its associated mineralization and mineralization distribution.The mineralization associated with medium-low temperature thermal fluids mainly occurs in the Au（Ag） mineralization that is closelyassociated with the fracture zone of the siliconized fractures and the layered pores of the Ag superimposed on the laminar sulfides in the Hercynian phase.（Au）-Cu-Zn-Pb mineralization occurred in the ore-bearing areas of Xiaolashan,Gangnan,Dengjiashan,Dongleiwan,Jinjiwo,Baiyangjing and other places in.
