沉积盆地中的流体包裹体：理论基础、图解与分析方法

本文主要介绍如何利用流体包裹体来获得合理的数据。首先对H2O-体系进行总结，着重介绍利用显微测温法和其他新的分析技术来确定流体的组成，并举例说明流体混合在流体包裹体研究中的应用。介绍了H2O-(气)-盐体系特别是CO2-CH4体系的图解，探讨了在低温下由于笼舍物的形成H2O-(气)-盐体系的复杂相变。重点介绍显微激光拉曼光谱仪在含甲烷水溶液流体中的应用，并根据相图详细讨论了如何确定流体的不混溶。

Fluid inclusions insedimentary basins: Theoretical basis, diagrams, analytical techniques

This paper is focused on the methods to study fluid inclusions in order to get the relevant information. First, the H_2O-salts systems are described and special attenlion is made upon the determination of the composition from microthermometric data and using new analytical techniques. Application to the study of fluid mixing, is exemplified. The different diagrams of H_2O-(gas)-salls systems with special attention of the CO_2-CH_4 system are presented. The complexity of the H_2O-(gas)-salls systems at low temperature, due to the presence of clathrales, is described. The use of micro-Raman spectrometry is specially focused for methanebearing aqueous fluids. The identification of the immiscibility process based on phase diagrams analysis is detailed.
