RT Journal Article T1 Las metamorfitas de Cumbres Calchaquíes, Tucumán (Argentina) y sus texturas deformacionales T1 The metamorphites of Cumbres Calchaquíes, Tucumán and their deformational textures A1 Omil, M. A1 Bobovnikov, J. AB 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 PB Sociedad Geológica de España YR 1999 FD 1999 LK http://hdl.handle.net/10272/9881 UL http://hdl.handle.net/10272/9881 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
