We interpret that these rocks were originated due to a seismic event at great depth (1.4 GPa) under high temperatures (740 ºC). Shear heating would have affected the still hot and mechanically rigid granulites and provoked melt formation. Ambient high P and T would have led to subsequent recrystallization of the previously formed melt giving rise to a weak planar fabricspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/UltramylonitesPseudotachylyteGranuliteCabo Ortegaljournal articleopen access
