Callovian to lower Kimmeridgian ammonite successions from West Sicily (Roccapalumba) and Northeast Iberian Range (Ariño, Teruel): A key for palaeogeo…
2010
La comparacion de las sucesiones de ammonites en el intervalo comprendido entre el Calloviense y el Kimmeridgiense inferior en la region de Sicilia occidental (Roccapalumba-Sciacca) y la Cordillera Iberica nororiental (Sierra de Arcos) muestra una clara similitud y paralelismo en el desarrollo estratigrafico. Esto incluye el registro incompleto del Calloviense inferior, una amplia laguna estratigrafica (Calloviense inferior-Oxfordiense medio) y un registro mas completo del Oxfordiense medio-superior (biozonas Transversarium-Bifurcatus) y Kimmeridgiense inferior. Esto permite inferir una evolucion paleogeografica paralela en ambas regiones del Tethys. Las asociaciones registradas de ammonite…

The Messinian salinity crisis in the Mediterranean basin: A reassessment of the data and an integrated scenario
2006
Abstract After a long period of controversial debate about the interpretation of the Messinian salinity crisis (MSC), a near consensus existed since the ODP Leg 42A for a model keeping the major lines of the deep basin-shallow water model initially proposed by Hsu et al. (1973) . The knowledge of the crisis was improved since the 1995s by the availability of a very accurate astronomically calibrated timescale. The debate about its interpretation was then reactivated by several new scenarios that questioned most the major aspects of the previous classical models. The updated re-examination of the most salient features along with consideration of the hydrological requirements for evaporite de…

Paleoecological constraints on reef-coral morphologies in the Tortonian-early Messinian of the Lorca Basin, SE Spain.
2004
Coral reefs represent one of the main carbonate factories that contributed to the control of the stratigraphic architecture of carbonate platforms, which had a widespread development during the late Miocene in the paleo-Mediterranean area. The late Miocene reef complexes of the Lorca Basin in southeastern Spain are composed of five mixed siliciclastic/carbonate units, middle Tortonian to early Messinian in age. The development of coral reefs probably ceased when the first evaporitic event occurred in the basin centre in the early Messinian. This study mainly focuses on the response of reef communities and the modifications of reef organisation to global and regional parameters. At the platf…
