The Sierra de Comechingones was affected by four major deformation phases (Martino et al., 1995).D 1 is poorly preserved as a gneissic foliation folded by rootless D 2 folds. D 2 deformation is characterized by mineral segregation and folding. It took place during prograde metamorphism, probably close to the metamorphic peak (Gordillo, 1984).This timing is suggested by the observation that ...
