The Minas de Henarejos basin (Iberian Ranges, Central Spain): precursor of the Mesozoic rifting or a relict of the late Variscan orogeny? New sedimentological, structural and biostratigraphic data

[EN] The tiny outcrop of the mining area of Minas de Henarejos is unique among the early post-Variscan basins of the Iberian Ranges, Central Spain, for several reasons: Its age, considered up now to be Late Carboniferous (Stephanian B-C), its syn-sedimentary compressional structures and the thick co...

A re-assesment of the biostratigraphic range of its macroflora shows that it is representative of the hygrophytic assemblage that ranges from the Late Carboniferous to the Early Permian, coeval with the so-called “Autunian” assemblages. Nothing prevents this basin to be considered coeval with other continental basins of Early Permian age in the Iberian Ranges. Compressional structures can be related to a right restraining bend in the sinistral N-S Teruel strike-slip fault system that created a synformal basin in the underthrust block.[ES] El pequeño afloramiento de la zona minera de Minas de Henarejos es único entre aquellos que conforman las cuencas de las primeras fases de los últimos estadios de la orogenia Varisca en la Cordillera Ibérica, en el Centro de España, debido a diferente motivos: su edad, considerada hasta nuestros días como Carbonífero Superior (Estefaniense B-C), sus estructuras sinsedimentarias de tipo compresional y las potentes capas de carbón que aparecen en la parte más alta de la serie. Una revisión del rango biostratigráfico de su macroflora muestra que ésta constituye una asociación higrofítica que abarca desde el fi nal del Carbonífero hasta las etapas iniciales del Pérmico, coetánea con la también denominada “asociación Autuniense”. No hay datos que estén en contra de que esta cuenca sea coetánea con otras cuencas continentales del Pérmico Inferior de la Cordillera Ibérica. Las estructuras compresionales podrían estar relacionadas con un bucle compresivo diestro dentro del sistema de fracturación de desgarre de dirección N-S de la denominada falla de Teruel, creando una cuenca sinformal en el bloque que quedaba hundido.This is a contribution to Research Project CGL 2005- 01520/BTE of the Ministry of Education and Universities, Spain.
