pseudosection, experimental petrology, Ollo de Sapo gneissAbstract
During the last years, a couple of softwares to model the behaviour of a rock under P-T-X changes using thermodynamic databases have been developed. The result of this model is a pseudosection or projection in the P-T plane of a phase diagram of a system at a fixed composition, this is, a phase diagram section. Although its utility has been well demonstrated, a comparison between theoretical and experimental data is advisable to see the degree of approximation of the theoretical model to the reality but also to consider the kinetic effects in experiments. In this paper, theoretical and experimental results of the melting of the Ollo de Sapo Gneiss are compared.
