Editing Aragon (section)

==== Depression of the Ebro ====
The Aragonese central depression includes a wide lowland area, which is also the central part of the [[Ebro Valley|Depression of the Ebro]]. North of the river there is the [[Sierra de Alcubierre]] ranges ({{val|811|u=m}}) one of the typical limestone plateaus of the valley.

The [[Ebro Valley]] is a tectonic pit filled with sedimentary materials, accumulated in the [[Cenozoic|Tertiary age]] in horizontal series. In the center, fine materials such as [[clay]]s, [[plaster]]s and [[limestone]]s were deposited. To the south of the [[Ebro]] there are the limestone plateaus of [[Borja, Province of Zaragoza|Borja]] and of [[Zaragoza]].
