Calizas oolíticas entre facies pelágicas en el Jurásico medio de Iznájar (Prov. de Córdoba, Subbético): significado paleogeográfico y paleobati métrico
On the top of the Zegrí Fm (Aalenian-Bajocian) oí the Median Subbetic in the Iznajar area (south of the Córdoba province) oolitic limestones outcrop, interbedded between pelagic facies. These oolitic limestones were previously interpreted as calcareous turbidites. The detailed study of their microfa...

| Sumario: | On the top of the Zegrí Fm (Aalenian-Bajocian) oí the Median Subbetic in the Iznajar area (south of the Córdoba province) oolitic limestones outcrop, interbedded between pelagic facies. These oolitic limestones were previously interpreted as calcareous turbidites. The detailed study of their microfacies, stratigraphic location, geometry of the sedimentary beds and sedimentary structures has allowed us to interpret these limestones as deposited in isolated carbonate platforms similar to the recognized in other areas of the Median Subbetic. This interpretation asserts that the overlying and underlying pelagic sediments were deposited (o a moderate depth (some hundreds of meters) |
