摘要
针对目前熔—流包裹体研究中对其成因性质重视不够的现象，指出在使用这一术语时，首先应以其成因性质为原则；认为只有那种在硅酸盐熔体与Ｈ２Ｏ（ＣＯ２）流体不混溶体系中，同时捕获硅酸盐熔体相与流体相的那些异常包裹体才适于称作熔—流包裹体；至于那种仅捕获了硅酸盐熔体相，由于圈闭后发生演化，从中分异出流体相的包裹体是一种正常熔融包裹体，不宜将其与异常熔—流包裹体同归一类；并以尖峰岭似伟晶岩黄玉中的熔—流包裹体为例，说明其主要特征。
There exists a mixup in the terminology of “meltfluid inclusion”In this paper the authors discuss the connotation of meltfluid inclusions and demarcate that only the anomalous inclusions which simultaneously captured the silica melt and fluids(H2O,CO2 etc.)in a immiscible meltfluid system may be called “meltfluid inclusion”;and those should be called melt inclusions which consist presently of silica melt and fluids but only a melt phase was captured during the inclusions were trapped.Taking the inclusions in topaz from the Jianfengling pegmatoid for an example,the authors describe in this paper the characteristics of the meltfluid inclusions.
