Sumario:Phyllonites which crop out in the northeastern part of Cumbres Calchaquies are the result of regional metamorphism, greenschist facies, with additional cattaclastic metamorphism. They have characteristic deformational textures developed in the ductile and brittle fields, and blastic textures in lesser degree. This textural coexistence is interpreted as the result of polydeformation, with variable physical and chemical characteristics, while the temperature remained in the biotite isograde, according the observed mineral paragenesis
