Tectonically driven landscape development within the eastern Alpujarran Corridor, Betic Cordillera, SE Spain (Almerı́a)
The Betic Cordillera is a topographic manifestation of Miocene to recent collision between the African and the European plates. Mountain ranges in the Internal Zone of the Betic Cordillera are exhumed massifs of metamorphic and sedimentary rocks, and are surrounded by low-lying sedimentary basins. The Neogene history of mountain range uplift and basin formation in the Betics is well studied, bu...
متن کاملTiming of tectonic events in the Alpujárride Complex, Betic Cordillera, southern Spain
Ar–Ar and fission-track dating from four low-grade sections in the Alpujárride Complex sheds light on the timing of the early contractional history of these high-pressure metamorphic units, and their subsequent exhumation during the early Miocene extensional collapse of the Betic orogen. White mica grains from the lowest-grade rocks yield partly reset detrital Ar–Ar ages; where deformation and ...
متن کاملLower-middle Eocene benthic foraminifera from the Fortuna Section (Betic Cordillera, southeastern Spain)
Benthic foraminifera were studied as part of an investigation of the Fortuna Section (Betic Cordillera, Southeastern Spain), undertaken to document a candidate section for the Global Stratotype Section and Point (GSSP) for the base of the Lutetian Stage (Ypresian/Lutetian boundary). Benthic foraminiferal assemblages in this section are mostly dominated by calcareous taxa (~50-96%) and by infaun...
متن کاملEnigmatic Fossils from the Lower Carboniferous Shrimp Bed, Granton, Scotland
The Lower Carboniferous (Visean) Granton Lagerstätte (Edinburgh, Scotland) is principally known for the discovery of the conodont animal, but has also yielded numerous crustaceans and other faunas. Here we report on small branching colonies, reaching 10 mm in length. They are small, erect, arborescent, and irregularly branched with predominant monopodial and dichotomous growth. They bud in a si...
متن کاملExhumation of high-pressure metapelites and coeval crustal extension in the Alpujarride complex (Betic Cordillera)
The current configuration of the Alpujarride complex (Befic Orogen) comprises a stack of thinned tectonic units, made up mainly of continental crest. P T path modelling in different levels of an Alpujarride unit (the Salobrefia tectonic unit) reveals a high-pressure metamorphic stage followed by subsequent decompression at nearly isothermal conditions. Nevertheless, the P T conditions differ fr...
