Fluid inclusions, Mineralizing fluids, Fluid evolution, Mineralization mechanismAbstract
Objective: Fluid inclusions are microfluids trapped within mineral crystals during their growth. These fluid droplets are the only direct observational samples which can invert the physicochemical condition and trace back its source as well as reveal the origin of mineral deposit. In order to comprehensively understand the petrographical, thermodynamic data on and compositional characteristics of the included fluids and what they imply for the history of mineralizing fluid evolution. Methods: To make a systematic and detailed division of fluids, use the petrographic division; analyze various microscopic thermometric data. Use laser Raman spectrum detection technology for detection, follow isotope tracing to track its movement, precipitation, etc., with the mass balance method, thermodynamic state equation method; Results: Temperature, Salinity Evolution of Inclusions has the same trend of uniform evolution, it is very accurate to display the mineralization dynamics process such as cooling, boiling (non-miscible), fluid mixing etc. in the fluid system; Volatile Components and Trace Element Composition can reflect the transport and precipitation way of metal complex. Concusions: Fluid inclusion can play an important role of divide the stage of mineralizing, it also can be called "Mineralization Phaze indicator" which give its microfluric Dynamic evidence to prove at mining deep drilling when build a regional scale model of mineralized zone: It is inevitable that the site multiple scale andmultiple methodanalyses of fluid inclusions, if we wantto know about how these minerals form fluids evolvesin the future.
