Abstract:

Abstract:  Using Diamond Anvil Cell combined with the micro Raman spectroscopy, the author has obtained the quantitative relationships among Raman shifts,  pressure and temperature for the vibration of O—H in H2ONaCl, C—O in CO2-3, S—O in SO2-4 and C—H in nheptanecyclohexane. On the basis of these relationships, we can determine the inner pressure for the fluid inclusion and further determine the isochore. It is not only helpful in obtaining the forming temperature and  pressure for minerals, but also able to provide the information of the chemical composition of the fluid inclusion.

Key words:

Key words: fluid inclusion; inner pressure; isochore; high temperature and high pressure; Raman shift
