During exhumation process, the initial information of a fluid inclusion is overwhelmed by various confounding factors such as deformation and decrepitation. These factors can be detected by slight changes in fluid density. Precise measurement of the fluid density at an arbitrary temperature and pressure is expected to elucidate the physicochemical characteristics of paleo fluid. We investigated the relations among temperature, density, and CO2 Raman spectra using CO2 fluid inclusions.
