The Crevillente and Abanilla mountain ranges form the same structural lineation but show a quite different
morphology. The first one is made by calcareous rocks mainly jurassic and cretaceous likewise the Abanilla
is made by keuper facies which includes blocks. This keuper facies are not Triassic but Miocene which are
interpreted as an ancient salt glacier. Their different litologies of both sierras is due to the activity of the
Puerto de Barinas Fault, a transverse fault to the Crevillente-Abanilla lineament. This litological difference
in the same structural lineament could be explained as produced before (pre-late Tortonian) the elevation
of both sierras (latest Messinian
