In the southwestern margin of Gondwana, preserved in the Argentinean-Chilean Andes (28-38 S latitude),three subduction events, Famatinian, Chanic and Gondwanan, took place from the Ordovician tothe middle Permian. The first two culminate in collisional orogens in Middle Ordovician and LateDevonian times respectively, while the Gondwanan is a subduction-related orogen, developed in lateCarboniferous-middle Permian times. This model is only valid for these latitudes, which coincide withthe N and S limits of the Chi-Cu continental fragment (Chilenia þ Cuyania subplates). Northern andsouthern limits of this continental fragment coincide with two major Andean lineaments, Valle Anchoand Huincul respectively.
