Not as hot we thought Earth's early oceans appear not to have been some suggested. The oxygen isotope composition of marine carbonates has changed markedly over the past 3.5 billion years. However, it difficult determine whether that is because a cooling seawater (from temperatures high 70°C) or an actual change in water. Galili et al. calibrated temperature-dependent fractionation between iron oxides and aqueous solutions constructed record covering 2 Their findings suggest water, rather...
Abstract Meter-scale, peritidal carbonate cycles are a common feature of the geological record but debate continues about what processes lead to their formation. Three conceptual models, or combination thereof, commonly invoked explain cycle formation; eustasy, tectonics, autocyclicity. These three models tested with large new dataset from different Early Jurassic plate margins western Tethys. Study seven logged sections Spain, Italy, Greece, Tunisia, Morocco, and Gibraltar enables an...
Abstract Lower Priabonian coral bioherms and biostromes, encased in prodelta marls/clays, occur the Aínsa‐Jaca piggyback basin, South Central Pyrenean zone. Detailed mapping of lithofacies bounding surfaces onto photomosaics reveals architecture buildups. Coral lithosomes either isolated or amalgamated larger Isolated are 1 to 8 m thick a few hundred metres wide; clay content within colonies is significant. Stacked form low‐relief buildups, commonly 20 30 thick, locally up 50 m. These...
In the northeastern Gulf of Mexico, Upper Jurassic Smackover inner ramp, shallow-water thrombolite buildups developed on paleotopographic features in eastern part Mississippi Interior Salt basin and Manila Conecuh subbasins. These thrombolites attained a thickness 58 m (190 ft) were present an area as much 6.2 km2 (2.4 mi2). Although these have been exploration targets for some 30 yr, new field discoveries continue to be made this region. Thrombolites best hard substrate during rise sea...
Some aspects on the age and correlation of upper Barremian-lower Aptian stratigraphic units NW Maestrat Basin were uncertain prior to this study, due differing lithostratigraphy marginal Oliete subbasin compared more depocentral Galve Morella subbasins. New magnetostratigraphic, ammonite sedimentological data presented in study refine sequence stratigraphy succession, enabling a direct precise across these Three third-order TR sequences are identified. The lower boundary Sequence 1...
La Cantalera is an accumulation site for fossil vertebrates consisting mainly of teeth and isolated postcranial remains. It has the greatest vertebrate biodiversity any from Hauterivian-Barremian transition in Iberian Peninsula. Up to now, 31 taxa have been recognized: osteichthyan (Teleostei indet.), two amphibians (Albanerpetonidae indet. Discoglossidae a chelonian (Pleurosternidae? lizard (Paramacellodidae? four crocodylomorphs (cf. Theriosuchus sp., Bernissartiidae indet.,...
ABSTRACT This paper reports on the structural and sedimentary evolution of middle to late Eocene Prepyrenean External Sierras (southern Pyrenees, Spain). The initiation, duration kinematics a set growth structures that developed in shallow marine depositional setting is documented. detailed analysis syntectonic sediments not only confirms already known east west progression deformation, but also reveals continued early formed as later ones propagate towards foreland. units coevally deposited...
Abstract A 380 m thick Aptian platform to basin transition has been studied along a 16 km long transect of excellent and continuous outcrops in NE Spain. The series dated using biostratigraphy (foraminifera ammonites) carbon-isotope stratigraphy, subdivided at four scales depositional sequences. marine succession is into two-large scale sequences separated by middle sub-aerial exposure surface. characteristic trend the floral-faunal fossil assemblages present, which evolves from...
Abstract The sauropod Aragosaurus ischiaticus Sanz, Buscalioni, Casanovas & Santafé, 1987 was the first dinosaur to be described in Spain. holotype recovered from site of Las Zabacheras (Galve, Teruel province). This has traditionally been situated El Castellar Formation (in lower part Wealden facies). Recently, it proposed that remains stem Villar del Arzobispo (late Tithonian–upper early Berriasian), which would mean almost 15 million years older than previously thought. Detailed field...
Abstract The complex interplay between shallow-water carbonate production, pelagic sedimentation, and sediment erosion redeposition on a Kimmeridgian ramp is analysed from field data computer modelling. Field come reconstructed cross-sections near Zaragoza Teruel, NE Spain. Inner areas are dominated by coral patch reefs, ooid shoals bioclastic packstones grainstones, whereas middle typified tempestites pinnacle reefs. Outer muds marls. large-scale stratigraphic features of the simulated...
ABSTRACT No counterparts to epeiric‐sea carbonate ramps are known in present‐day environments. This hinders the interpretation of factors controlling growth and evolution these depositional settings. In this study we analyse facies geometries two Jurassic examples both from outcrop through computer modelling. analysis is constrained by important features Oxfordian Kimmeridgian ramps: firstly, they very well exposed, allowing accurate reconstruction a 200‐km section proximal distal ramp...
En Galve (Teruel) hay más de 50 localidades con restos vertebrados continentales en las Formaciones Higueruelas (Titónico), Villar del Arzobispo (Titónico superior-Berriasiense medio), El Castellar (Hauteriviense terminal-Barremiense basal) y Camarillas (Barremiense inferior).Por tanto, «Galve» no es un único yacimiento mesozoicos, sino una localidad numerosos yacimientos intervalo Titónico-Barremiense, que geológicamente pertenecen a la Cuenca cretácica inferior Maestrazgo (Cordillera...
The lateral continuity and facies heterogeneities of metre-scale cycles in a greenhouse Lower Jurassic (Sinemurian) carbonate ramp from the northern Iberian Basin (Spain) was evaluated extensive field analysis carried out on well-exposed 12 km long outcrop. Eleven high-frequency continuous their bounding surfaces are traceable laterally through entire However, three these found to split into discontinuous more limited distribution (up 3 5 extent). have similar expression one-dimensional...
