Estratigrafía del Eoceno Prebético: edad, evolución y organización en ciclos

Abstract

Se han estudiado trece secciones a lo largo de la cordillera Bética (sectores de Alicante, Murcia, Granada y Jaén) en el Eoceno Prebético. Los ambientes sedimentarios en su mayoría consisten en facies marinas someras. Se propusieron tres formaciones estratigráficas informales datadas con foraminíferos planctónicos, nanoplancton calcáreo y macroforaminíferos bentónicos: (1) fm margoso-arcillosa inferior; (2) fm intermedia calizo-calcarenítica y (3) fm margoso-arcillosa superior. La arquitectura estratigráfica muestra límites diacrónicos y pasajes laterales que representan la plataforma interna y externa (talud superior en algunos casos). La fm margoso-arcillosa inferior comienza en el Paleoceno superior en algunas secciones. Tanto el límite inferior como el superior de la fm intermedia calizo-calcarenítica son diacrónicos, y van desde el Ypresiense basal hasta el Lutetiense medio y desde el límite Ypresiense-Lutetiense hasta el Bartoniense inferior, respectivamente. La edad superior de la formación arcillosa-margosa superior alcanza el Priaboniense superior. El Eoceno Prebético en las secciones estudiadas se organiza en secuencias regresivo-transgresivas (RT) formadas a su vez por ciclos RT menores.

Thirteen sections have been studied along the Betic Cordillera (Alicante, Murcia, Granada and Jaen sectors) in the Prebetic Eocene. The sedimentary realms were mostly shallow marine. Three informal stratigraphic formations were proposed and dated with planktic foraminifera, calcareous nannoplankton and Larger Benthic Foraminifera: (1) lower marly-clayey fm; (2) intermediate limestone-calcarenite fm; and (3) upper marly-clayey fm. The stratigraphic architecture shows diachronous boundaries and lateral changes representing the internal and external platform (upper slope in a few cases). The lower marly-clayey fm starts in the Upper Paleocene in a few sections. Both lower and upper boundaries of the intermediate limestone-calcarenite fm are diachronous, ranging from Early Ypresian to Middle Lutetian and from Ypresian-Lutetian boundary to Early Bartonian, respectively. The top age of the upper marly-clayey formation is Late Priabonian. The Prebetic Eocene in the studied sections consist of in regressive-transgressive (RT) sequences made of smaller RT cycles.
