Resum
The study of facies and sequences of the "Lithiotis" limestones of the Subbetic Liassic outcropping North of Vélez Rubio allows us to propose that they were deposited in a shallow marine carbonate bank which was isolated from the South-Iberian continental margin by a deeper seaway with hemipelagic facies. Two basic types of shallowing upward elemental sequences have been distinguished. A strong ressemblance between the "Lithiotis" lime stones and the Lower Cretaceous rudist limestones is also suggested. The widespread regional distribution of these facies allows to distinguish this Eastern Betic area, during Lower to Middle Liassic times, as an independent paleogeographic realm, including the southern part of the Median Subbetic and the Internal Subbetic.
