Resumen

Phase relations in the haplogranitic system have been broadly experimentally studied, but there is still an open field of discussion in experimental petrology concerning phase relations in natural granitic systems, Among other ferromagnesian phases occurring in granitoids, cordierite is controversial and its appearance has not jet been constraint. In this preliminar work, we have studied cordierite stability using a thermodynamic data set for temperatures between 750 and 1 000 °C and pressures from 3 to 6 kbar. From the results presented here, cordierite could be a saturated phase of the studied system, but nucleation problems in experiments carried out under similar conditions do not reproduce this stability
