Major scale structure of the marbles situated between Cóbdar and Macael (Nevado-Filábride Complex, Betic Cordillera, Almería province, Spain), and general stratigraphic arrangement

Zusammenfassung

In the area situated between the localities of Cóbdar and Macael appears one of the best outcrops of the formation of schists and marbles situated in the upper part of the Nevado-Filábride lithological succession. In this sector, several tectonic units were defined, based in metamorphic differences, and also, this formation has been considered as forming a wide shear zone separated by a thrust contact from a lower unit. Our macro scale structural analysis points that the basal contact of the formation seems to be stratigraphic and is partially reversed, describing a NNE verging recumbent synform. The alternation of schists and marbles within the formation is generally well exposed, also with NNE verging folds of minor size, although in the upper part of the formation these folds are larger in several points. Levels of marbles laterally divide in many others or grade to calcschist and then disappear. These data seems to contradict the existence of the above-cited units and that of a general wide shear zone.
