Title: APPLICATION OF DECREPITATION METHOD IN ORE DEPOSITS
Abstract: Decrepitation method is a fast and economic method to collect information of fluid inclusions.Based on decrepitation data and other results,it is suggested that ore-forming fluids of quartz vein and altered rock type ores in the Hatu gold deposits,north Xinjiang,are different.Gold mineralization of quartz vein and altered rock types occur separately.There is a strong α-β changed apex of quartz in the decrepitation curve in the Kuoerzhenkuola,Hatu,Kuangguer and Hongshi gold deposits.Those ore-forming fluids are related with deep hot intrusions,and there might exist blind Cu and Au orebodies in the depths.By contrast,there is fear of blind Cu and Au orebodies in depths of Shiyingtan,Yemaquan,Kekesayi and Buerkesidai gold deposits.This is approximately in agreement with the results of ore prediction in the deposits,and decrepitation method can reflect important information for mineralization.Although limitation and incertitude factor of decrepitation method restrict its application to a certain degree,the shown results indicate that decrepitation method possesses dominance that homogenization temperature cannot replaced,if we make best use of the advantages and bypass the disadvantage.
