摘要
通过矿物包裹体研究,对沙柳河南区有色金属矿床的形成,按照成矿阶段作了温度、压力、深度等物理环境的时空归纳。对成矿流体的成分,在阴、阳离子三角图解上作了不同成矿阶段富集程度的讨论;对成矿流体的盐度、密度、pH 值 Eh 值、fO_2、fCO_2进行综合分析。它们代表了本矿床形成过程中必备的物理化学条件。
Through the studying mineral inclusion,based on metallogenic stage or mineralized al-teration zone,the author has Summarized the space—time regulation of the physical environment suchas temperature,pressure,depth,and so on of the southern Shaliuhe nonferrous—metal deposit,dis-cussed the mineralizing fluid composition and enriching extent of differnt metallogenic stage on anion—cation trangular diagram,and analysed the salinity,density,pH,Eh,fO_2,fCO_2 of mineralizing flu-id.At last it has been pointed that the aspects listed above represent the best physical—chemical condi-tion for this deposit to be formed.
