BASIC program for interpretation of microthermometric data from H 2 O and H 2 O-NaCl fluid inclusions

Abstract Empirical equations fitted to the experimental data of R. Hilbert and M. Gehrig have been used in a BASIC program to locate temperature pressure coordinates of isochores for H 2 O and H 2 ONaCl fluids to 700°C. The program also permits calculation of P-V-T-X relations at homogenization point of fluid inclusions. Isochoric coordinates based on the data of R. Hilbert and M. Gehrig show increasing divergence from other published tables towards higher temperatures, pressures, and NaCl contents.
