| The fluid-inclusion geochemistry researches the characters and the interrelations of the fluid-inclusions,offers the data of physical chemistry and energetics for the ore-forming processes,discusses the geological histories of geochemistry and evolement, and is a used science for seeking the deposits.Using fluid-inclusion petrography and microthermometry, using ZEISS Axioskop 40 mul-fuction polarizing microscrope and LINKAM THMSG 600 stage ,using homogenization and cooling to measure temperature ,and adding to the research material of preparent ,we did research about slices of the samples from the Fuliuling AuOre-Deposit in Guigang , Guangxi Province,then got the ore-forming temperature. Based on these works ,I tried to discuss the connections of the temperature、the salinity and the rich ore-bodies.The research of petrography and microthermometry of fluid-inclusion suggests, the Fuliuling AuOre-Deposit in Guigang , Guangxi Province alongs to minuteness dip-dye ore-deposit. Using homogenization to measure temperature,we found,the temperature mostly is 100℃~200℃, the salinity mostly is 2~10 wt%NaCl,the density mostly is 0.85~1.00 g/cm3 ,the stress mostly is 40~80bar,the depth is under 2.5km.The stress of Liujiuding mainly is in the 40~80bar,and higher than the 40~60bar of Liumei.The depth of mineralization in Liumei is also slightly shallower than in Liujiuding.The high-value gold section of Liujiuding is the 130m segment, and the temperature is 200~240℃. The high-value gold section of Liumei is the 10~85m segment, and the temperature is about 140℃.By testing the lanthanon,we found,the ore、the stratum near the deposit and the area stratum is the same in origin.Compared with similar deposits in China, the mineralization temperature of the Fuliuling AuOre-Deposit is in the lower range. |
