Comparison of the Thermometery-Barometery methods by using Thermocalc and Theriak-domino to study Calc- silicate Hornfelses in Cheshin, Hamedan

Journal of Economic Geology, 2019
Introduction The pseudo-section method, first proposed by Hensen (1971), is used today by scientists to determine the thermodynamic conditions of mineral crystallization and modeling in metamorphic lithology (Hoschek, 2004; Omrani et al., 2013).
