Fluid inclusions in sedimentary basins: Theoretical basis, diagrams, analytical techniques
|
Abstract:
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.
