Distribución paleogeográfica de las unidades del Pérmico y del Triásico en el sector Molina de Aragón-Albarracín

Journal of iberian geology: an international publication of earth sciences (1987)

Marta Pérez‐Arlucea

En los sistemas Permico y Triasico del sector Molina de AragonAlbarracin (Cordillera Iberica) se pueden diferenciar dieciseis unidades litoestratigraficas. La inferior no ha podido datarse en esta zona, por su posicion estratigrafica y caracteristicas litologicas puede pero ser equivalente a unidades descritas como «Autuniense por autores previos, en areas proximas. Por encima aparece una unidad terrigena correspondiente a las facies Saxoniense, que al SE es concordante con el Buntsandstein, pero se separa en el NO por una suave discordancia cartografica. En el Buntsandstein se pueden diferenciar claramente las cinco unidades que definio RAMOS (1979) en la zona adyacente hacia el NO. Estas unidades presentan, sin embargo> una distribucion muy irregular dentro de la region estudiada (fig. 2). El Muschelkalk presenta, en el E, dos barras carbonaticas separadas por un tramo terrigeno-evaporitico. Sin embargo, hacia el N la barra carbonatica inferior se acuna apoyandose, directamente sobre el Buntsandstein, el tramo intermedio antes mencionado. Por ultimo, tambien pueden diferenciarse cuatro unidades litoestratigraficas en el Keuper. La descripcion detallada de estas unidades se ha presentado ya en publicaciones anteriores (p. e$: PEREZ ARLUCEA y SOPENA, 1985) y, por tanto, se obviara en este trabajo. Se exponen, sin embargo, algunas de las caracteristicas mas destacables, haciendo especial mencion a la distribucion paleogeografica de las unidades y a su evolucion * Departamento de Estratigrafia, Facultad de Ciencias Geologicas, Universi dad Complutense> Madrid. 607 general. La distribucion espacial de estas unidades esta muy condicionada por los movimientos tectonicos contemporaneos con la sedimentacion, sobre todo> en el caso de las unidades clasticas inferiores. Uno de los rasgos paleogeograficos mas notables dentro de este area es el «Umbral del Tremedal», que permanecio durante gran parte del Permico y del Triasico como una zona de «horst. Un hecho destacable es Ja existencia de un importante nivel de alteracion en la parte superior del Buntsandstein. Esta alteracion implica un momento generalizado de «no previo a la primera transgresion del Tethys, que dio lugar a la sedimentacion de la barra carbonatica inferior del Muschelkalk. El nivel de alteracion esta mas desarrollado sobre el Umbral del Tremedal, donde la sedimentacion finalizo con anterioridad. Las unidades del Muschelkalk presentan una disposicion en «onlap'> debido a que la segunda transgresion tuvo un mayor avance hacia las areas continentales que la primera, cuyo limite queda registrado dentro de la zona estudiada.

Textural characteristics and facies of sand‐rich contourite depositional systems

Sedimentology (2018)

Rachel Brackenridge Dorrik A. V. Stow Francisco J. Hernández‐Molina Claudia Jones Anxo Mena

Abstract This work presents a detailed study of CONTOURIBER and Integrated Ocean Drilling Program 339 sediment data targeting sand‐rich contourites in the Eastern Gulf of Cadiz. All of the collected sediments are interpreted as contourites (deposited or reworked by bottom currents) on the basis of oceanographic setting, seismic and morphometric features, and facies characteristics. A variety of sandy and associated facies are found across the study area including: (i) bioturbated muddy contourites; (ii) mottled silty contourites; (iii) very fine mottled and fine‐grained bioturbated sandy contourites; (iv) massive and laminated sandy contourites; and (v) coarse sandy/gravel contourites. The thickest sands occur within contourite channels and there is a marked reduction in sand content laterally away from channels. Complementary to the facies descriptions, grain‐size analysis of 675 samples reveals distinctive trends in textural properties linked to depositional processes under the action of bottom currents. The finest muddy contourites (<20 μ m) show normal grain‐size distributions, poor to very poor sorting, and zero or low skewness. These are deposited by settling from weak bottom currents with a fine suspension load. Muddy to fine sandy contourites (20 to 200 μ m) trend towards better sorting and initially finer and then coarser skew. These are typical depositional trends for contourites. As current velocity and carrying capacity increase, more of the finest fraction remains in suspension and bedload transport becomes more important. Clean sandy contourites (>200 μ m) are better sorted. They result from the action of dominant bedload transport and winnowing at high current speeds. The results highlight the importance of bottom current velocity, sediment supply and bioturbational mixing in controlling contourite facies. Despite growing interest in their hydrocarbon exploration potential, contourite sands have remained poorly understood. This research therefore has important implications for developing current understanding of these deposits and aiding the correct interpretation of deep marine sands and depositional processes.

The Ortegal spur contourite depositional dystem (Bay of Biscay): the implications of the Mediterranean Outflow Waters in sedimentary processes and cold-water coral ecosystems

F. Javier Hernández‐Molina Miguel Ãngel Nombela David Van Rooij Gabriel Rosón Gemma Ercilla

This study illustrates the occurrence of a Contourite Depositional System (CDS) at Ortegal Spur (northern Galicia margin, Bay of Biscay), between 43.7oN-44.35o N and 8.25o W-9.25oW. The study area corresponds with a fishing ground named “A Selva” which extends 70 miles northwest from Ferrol. This area is characterised by a well defined upper and middle slope, under the influence of the Mediterranean Outflow Water (MOW).
