Abstract

The lithological sequence of the Nevado-Filábride Complex (Betic Cordillera, S Spain) in the sierras Nevada and Filabres can be divided into four formations. From bottom to top the first corresponds to dark schists and quartzites of about 3600 m thick. Above lie the quartzites of Benitagla and then the Tahal light schists, and at the top lies the schists and marbles Fm. The thickness of the upper formations is on the order of 2000 m. The passage between the formations is stratigraphic and transitional. The metamorphism is inverted, being of higher grade to the top. This feature led to the proposal of superposition of tectonic units, with a higher grade of metamorphism in the upper ones, but the tectonic contacts between these units, according to our data, simply do not exist. The deposit of the lower formation had a syntectonic-compressional character while the other ones formed in extensional and post-tectonic environment in relation to the Variscan orogeny. New faults then formed permitted the extrusion of igneous rocks, including some ultrabasic ones, which according to our scheme were extruded together with basic rocks, not linked to an oceanic crust.
