一种新型人工“流体包裹体”:融合二氧化硅毛细管技术

A new synthetic "fluid inclusion": The technique of optical fused silica capillary

利用融合二氧化硅毛细管技术制作了纯H2O体系、纯CO2体系、H2O-NaCl体系和H2O-CO2体系的人工包裹体样品,并对样品进行了显微测温和激光拉曼光谱测试工作。实验结果显示毛细管样品中的流体成分具有代表性,而且常规的流体包裹体显微测温和显微激光拉曼光谱分析技术完全适于毛细管样品的测试。对样品的显微测温和拉曼光谱研究结果表明毛细管样品能够作为标样,标定流体包裹体显微测温过程中的流体相变以及流体包裹体拉曼光谱,而且能够发展和建立拉曼光谱分析流体包裹体成分的方法。此次工作表明,融合二氧化硅毛细管技术为流体包裹体研究提供了一种新的手段,在包裹体研究领域有着广阔的应用前景。

Synthetic fluid inclusions in the systems of pure H2O,of pure CO2,of H2O-NaCl and of H2O-CO2 were made using the technique of optical fused silica capillary.Those capillary samples were analyzed by micro-thermometry and micro-spectroscopy.The experiment shows that the fluids in silica capillary are the representative of loading fluids,and the micro-thermometry and micro-spectroscopy,the two common approaches for measuring the fluid inclusion,are suitable to be applied to the analysis of capillary samples.The micro-thermometric and micro-spectroscopic results reveal that the technique of silica capillary gives us a better means to understand the phase equilibria during the progress of micro-thermometry and to characterize the spectra of inclusion fluids and to develop the methods of analyzing the fluid inclusion.This study demonstrates that the technique of optical fused silica capillary provides a new means for the study of fluid inclusion,which may be widely applied to the fluid inclusion study.
