| 摘 要： | 对南坑萤石包裹体研究发现,成矿热液温度、压力、盐度低;成分以F~-,Ca~(2+)为主;CO_2/H_2O比值小;fo_2低;氢氧同位素组成与当地大气降水同位素组成特征相同,表明南坑产于花岗岩断裂破碎带中的萤石矿床,成矿热液与物质来源都与花岗岩岩浆期后热液活动没有发生直接联系,属于与大气降水活动密切相关的脉状萤石矿床。

| Abstract: | The investigation on fluorite inclusions show that temperature, pressure and salinity of minerogenic solution are low; main composition of inclusion is F~-and Ca~(2+);CO_2/H_2O ratio and fo_2 low hydrogen and oxygen stable isotope composition are in accord with that composition of the local meteoric water. These charateristics reveals that minerogenic solution and ore-forming materials of Nankeng fluorite deposit locating in fracture zone of granite bear no relation to post-magmatic hydrothermal activities, fluorite deposit water. |
