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.
