摘要：

那程银金矿区位于吴川—四会大断裂中部主断裂东南侧，次级NE向运塘—三屋排断裂南东，黄岭顶—合水口断裂北西之复合部位。矿区内共发现含银金矿脉16条，均产于蚀变破碎带中。矿脉在空间排列上呈相互近于平行的雁行式左行排列的特点，圈定工业矿体2个。银金矿床的形成是原岩经构造破碎和蚀变作用后，金银富集含量明显增加，在多期次而强烈的地质作用改造后，大面积活化迁移，在有利部位富集，形成工业矿体，是构造活动、变质作用、交代作用和岩浆活动共同作用的结果，属中—低温热液破碎蚀变岩型银金矿床。

Abstract:

Nacheng silver gold deposit is located in the southeast of the center of Wuchuan-Sihui rift zone.It’s located in the southeast of northeast trending Yuntang-Sanwupai secondary fault and the northwest of Huanglingding-Heshuikou fault’s composite parts.16 silver-gold veins,which are produced in the altered fracture zone,has been found in the mine.In the spatial arrangement of the veins are the nearly parallel on echelon left rows. Two industrial ore zone have been delineated.The formation of silver-gold deposit is due to the tectonic fragmentation and alteration,the content enrichment of gold and silver increased a lot and were large-scale activated and migrated into the favorable positions by many times and strong geological reconstruction which finally came into being the industrial ore.It is the product of the tectonism,metamorphism,metasomatism and magmatic activities.It belongs to the medium-low temperature hydrothermal water fractured altered rock type of the silver-gold ore deposit.
