Evidences of amphibole and biotite breakdown can be seen in some volcanic rocks of the Tertiary and quaternary periods of Iran. This paper, investigates the breakdown of amphiboles in disequilibrium conditions. By investigation andesites of Quaternary pyroxenes northeast of Warzghan in northwest Iran, we obtained the combined temperature-pressure conditions of the amphibole crystals. Geothermometry and geobarometry based on amphibole single-phase compositions indicate that most of the amphibole crystals are not in equilibrium with hydrous melts containing ~64-69 wt% SiO2. In the pyroxene andesites of the region, some amphiboles have been breakdown. Investigations showed that the arrival of new and hot magma pulse caused the magma cell to migrate from deep levels (22.5 km depth and 7.5 kbar pressure) to shallower depths (21 km depth and 7 kbar pressure). This increase in temperature and decrease in pressure destroyed the stability conditions of amphibole and created the conditions for the growth of augite.
