Abstract
Postulated fluid-fluid immiscibility of 50–50% CO 2-N 2 mixtures has been checked by high-pressure experiments (<5 GPa; <400 K) and could be rejected. The implications for the interpretation of high-density fluid inclusions (<42 cm 3/mole) in eclogite and granulite-facies rocks are discussed: only models based on LG-immiscibility are applicable for molar volume calculations also in the very-high-pressure range. The position of the critical curve for CO 2-N 2 could be more accurately determined with the help of experimental and fluid inclusion data. The S 2-F isopleth and the three-phase (S 1S 2F) line have been established for 50.6% N 2 composition.
