Abstract

In the pre-Carboniferous Paleozoic basement of the San Rafael block, rocks located east of Los Reyunos Gondwanan thrust show chanic late-Carboniferous east-vergent structures and were generated in the absence of metamorphism. The rocks located west of Los Reyunos thrust were deformed by two sets of folds, the first usually west-vergent, under low grade metamorphic conditions. That is why the Reyunos thrust must be considered a reactivated chanic structure. Such chanic old thrust could be responsible for the superposition of the western branch of Chanic Orogen over its eastern branch which was produced as a consequence of the Chilenia - Cuyania collision.
