A NEW ALGORITHM AND COMPUTER PROGRAM FOR CALCULATION OF MOLAR VOLUME AND BULK COMPOSITION OF CH4-H2O-NACL FLUID INCLUSIONS

摘要

In addition to the CO_2-H_2O-NaCl system, the CH_4-H_2O-NaCl system is also the frequently encountered fluid in hydrothermal system, sedimentary terranes, and low to moderate metamorphic rocks. Thus it is important to determine the bulk composition and molar volume (V-x properties) of CH_4-H_2O-NaCl fluid inclusions for the exploration of ore deposits, oil and natural gases, and for modelling heat and mass transfer in various geological environments.
