对广东长坑金银矿床流体包裹体的研究表明 ,该矿床矿石中流体包裹体种类较多 ,以富气态烃包裹体与盐水溶液包裹体为主 ,包裹体相对含量统计表明 ,富气态烃包裹体占包裹体总数的大多数 ,表明成矿流体为富含气态烃的水溶液。金、银矿石均一温度测定主要集中在 16 0～ 2 6 0℃区间。单个包裹体的拉曼光谱分析结果证明 ,成矿流体成分与赋矿围岩有密切关系。成矿流体主要为盆地富含有机质的热流体
The study of fluid inclusions in the Changkeng gold-silver deposit in Guangdong shows that there are many fluid inclusions in the ore deposit, and the gas-bearing hydrocarbon inclusions and brine solution inclusions are the main types. The relative contents of the inclusions show that the gas inclusions The majority of inclusions account for the total number of inclusions, indicating that the ore-forming fluid is an aqueous solution of gaseous hydrocarbons. The average temperature of gold and silver ores is mainly in the range of 160 ~ 260 ℃. The results of Raman spectrum analysis of individual inclusions show that the composition of ore-forming fluid is closely related to the ore-bearing rocks. The ore-forming fluids are mainly organic fluids that are rich in organic matter in the basin
