流体包裹体研究是地质研究的重要手段之一,而流体包裹体各相的体积则是一个重要的参数。早期得不到体积数据,只能给出包裹体的二维面积。中国科学院地球化学研究所包裹体实验室曾提出一条换算曲线,根据二维面积推测体积,误差较大。Bodnar曾提出根据气泡直径和流体P-V-T-X性质计算包裹体体积的方法,本文对其未考虑到的情况进行了补充。还提出了根据实验资料用图解得到包裹体各相体积的新方法,并据实例比较了各种方法的优缺点。
Fluid inclusion research is one of the important aspects of geology study, and the volumes of individual phases in a inclusion are significant parameters. In early time, only the two-dimension area on the focus plane could be measured. A curve was proposed to estimate the volume of inclusion based on the two-dimension area, but the error is large. Bodnar suggested to calculate the volume of individual phase based on the diameter of the vaper bubble and the P-V-T-X properties of the fluid, and his method is supplemented in this paper for uncovered situation. A new method using figures obtained from experimental data is put forward here. Finally, an example is presented and methods mentioned above are compared.
