-Sector NW in which they emphasize the ranges of Urbión, Demanda and Cebollera. They are composed mainly by quartzites, shales and sandy, while the depressions that remain among them are covered with limestones. It was affected by the glaciers, for which we can appreciate glacial gaps, morrenics arches and other morphologies related to glacial processes.
-Sector central in which two branches are distinguished: the Castillian(occidental-western) and the aragonese one (eastern-oriental), in which we find the greatest mountain (Moncayo 2315 m). Among both is located the basin of Almazán. As a group, is constituted by a series of syncline and anticline toward the NE. The stones dominant are the calcareous in the mesozoic material and the quartzites in the Paleozoic, origin these of hardly stand out morphological leveled by the erosion and constituting thus a relief of type apalachense.
-Sector SE in which also the aragonese and castillian branches are distinguished, separated by the depression of the Alto Jiloca. This last one binds with the Coastal-Catalonian Chains in the arches of Portalrubio-Calanda. It is an assembly of structures hardly fold with Iberian direction (NW-SE) and Catalonian (NE-SW) extensively devastated. The stone dominant is the limestone, although in some zones remain the slaty.
