以H_2O-CO_2-CH_4-NaCl体系为代表的多气体组分与水、盐并存的流体广泛参与了各种成岩成矿过程,并指示这些地质作用的各种地球化学信息,且保存在矿物在生长过程中所圈闭的流体包裹体中。确定含气多组分盐水包裹体的组成与性质,是揭示地质流体的组成、性质以及相关成岩、成矿条件的重要途径。确定单个包裹体中流体组分和密度,通常基于直接的(如拉曼、红外、LA-ICP-MS)和间接的(如显微测温技术)方法。把显微测温与拉曼光谱技术相结合来确定含气盐水包裹体的总组成具
Hydrocarbon coexisting fluids, such as H 2 O-CO 2-CH 4 -Cl NaCl, are coexistent with various diagenetic mineralization processes and indicate various geochemical information of these geological processes, The fluid inclusions trapped in the growth process. Determining the composition and properties of gas-bearing multicomponent brine inclusions is an important way to reveal the composition and properties of geologic fluid and related diagenesis and metallogenic conditions. Determination of fluid composition and density in individual inclusions is usually based on direct (eg, Raman, infrared, LA-ICP-MS) and indirect (eg, microscopy) techniques. Combining microscopic temperature measurement with Raman spectroscopy to determine the total composition of gas-bearing brine inclusions
