Western Sector of the Fuegian Andes Deformed Complex (FADC-WS)

Abstract

The Mesozoic complex starts here from the simplest chrono-stratigraphic chart, consisting of a thick marine layer of Late Jurassic-Early Cretaceous age, superimposed to Jurassic volcanic and sedimentary rocks and overlain by Late Cretaceous marine sedimentary rocks, the whole sequence folded and metamorphosed. The marine Tertiary, folded as well, is overlying all the aforementioned units. Underlying the whole group there is a possible metamorphic basement. In this sense, several formations have been proposed, what in certain ways make much more complex the matter at the same time that they contribute to build a richer system of order and classification.
