Abstract：In northeast district of Guangxi,China,the micro-fine grain dissiminated type gold deposit is commonly distributed. Gaolong is one large scale gold deposit,which lies in the oxidization zone. The area lies in the south-eastern dectivity zone of Yun-Gui plateau. According to the deposit's geological characters, mineral's combination type and forming characters,the micro-fine grain dissiminate type gold deposits can be divided into two types as Gaolong and Jinya. Gaolong type gold deposit is mainly distributed in oxidized zone (weathering belt). In the area,only oxidized ores are found, noevidence of primery sulfide ores. All bodies were yielded in oxidized zone. At the lower part of the orebody, only nonoxidized structured quartzite ore bodies be found. According to ore type,three types of ore bodies can be divided as follow: a Texture quartzite type ore(keatite rock); b siliceous texture brecciated ore; c siliceous crushed crag ore. Two experiment were done to know how oxidation effect original minerals under the dif-firent pH,teperature and bacterium. Two types of the minerals can be devided into oxidized minerals and primary mineral (including pyritoides mineral, pyrite-arsenical type mineral, arsenical pyrite type mineral) According to the characteristics of the mineral's genesis and the mineral's paragenesis,we consider that Gaolong gold deposit is post-product in a cycle of metallogenetic epoch.
