The andean movements of groeber and the tectonic evolution of the southern central Andes

One of Pablo Groeber’s most significant contributions to the knowledge of the Andes was his study of the tectonic movements associated with the uplift of the Andean Cordillera. The data collected by Groeber in more than 40 years of fieldwork in the Andes of Neuquén, Mendoza and San Juan were systema...
