14 p, 1013.7 KB Mesozoic-Cenozoic stratigraphy of the Fuegian Andes, Argentina / Olivero, Eduardo Bernardo (CADIC-CONICET. Centro Austral de Investigaciones Científicas) ; Malumián, Norberto (SEGEMAR)
The stratigraphy of the Argentinean Fuegian Andes reveals contrasting Mesozoic-Cenozoic tectonic regimes. The Lemaire Formation, submarine complex of bimodal volcanites, breccias, and sedimentary rocks; the Yahgán Formation, volcaniclastic apron of deep-marine andesite-rich turbidites and mudstones; and the Beauvoir Formation, slope mudstones, all evidence late Jurassic early Cretaceous extension and consequent origination of the Rocas Verdes Marginal Basin. [...]

20 p, 5.3 MB Recalibration of the Tethyan shallow-benthic zonation across the Paleocene-Eocene boundary : the Egyptian record / Scheibner, Christian (Universität Bremen) ; Speijer, Robert P. (K.U. Leuven. Department of Earth and Environmental)
The Galala Mountains in Egypt provide an excellent platform-basin transect with deposits spanning the Paleocene/ Eocene (P/E) boundary. These interfingering deposits enable a recalibration between platform and open marine biostratigraphic schemes. [...]

(Royal Belgian Institute of Natural Sciences. Department of Paleontology) ; Speijer, R. P. (K.U.Leuven. Department of Earth and Environmental Sciences)
In order to unravel faunal and paleoenvironmental parameters in shallow marine settings prior to the Paleocene- Eocene thermal maximum, we investigated the Sidi Nasseur section (NAS) in Central Tunisia. [...]

29 p, 7.1 MB Late Maastrichtian-Early Paleocene sea level and climate changes in the Antioch Church Core (Alabama, Gulf of Mexico margin, USA): a multi-proxy approach / Schulte, Peter (Universität Erlangen. GeoZentrum Nordbayern) ; Speijer, Robert P. (K.U.Leuven. Department of Earth and Environmental Sciences)
The Antioch Church core from central Alabama, spanning the Cretaceous-Paleogene (K-P) boundary, was investigated by a multi-proxy approach to study paleoenvironmental and sea level changes within the wellconstrained sequence stratigraphic setting of the Gulf of Mexico margin. [...]

16 p, 11.6 MB Organic-Rich facies in the Sinemurian and Pliensbachian of the Lusitanian Basin, Portugal : Total organic carbon distribution and relation to transgressive-regressive facies cycles / Duarte, L. V. (Universidade de Coimbra. Departamento de Ciências da Terra and IMAR-CMA) ; Silva, R. L. (Universidade de Coimbra. Departamento de Ciências da Terra and IMAR-CMA) ; Oliveira, L. C. V. (PETROBRAS/RH/UP/ECTEP/PETROBRAS/RH/UP/ECTEP) ; Comas-Rengifo, M. J. (Departamento-UEI de Paleontología, UCM-CSIC) ; Silva, F. (Galp Energia)
The upper Sinemurian to Pliensbachian series of the Lusitanian Basin (Portugal) correspond to marly limestone sediments rich in benthic and nektonic macrofauna. This sedimentary record includes several intervals of organicrich facies, which are particularly well developed in the western sectors of the basin. [...]

23 p, 18.0 MB Earliest Pragian (Early Devonian) corals and stromatoporoids from reefal settings in the Cantabrian Zone (N Spain) / Fernández-Martínez, E. (University of Léon. Faculty of Biology and Environmental Sciences) ; Fernández, L. P. (University of Oviedo. Department of Geology) ; Méndez-Bedia, I. (University of Oviedo. Department of Geology) ; Soto, F. (University of Oviedo. Department of Geology) ; Mistiaen, B. (Université Catholique de Lille. Laboratoire de Paléontologie stratigraphique)
The oldest reefal episode in the Cantabrian Zone (earliest Pragian) consists of small biostromal patch reefs, mainly built by corals and stromatoporoids, and developed on a storm-dominated ramp. Four outcrops provide the stratigraphic framework in which these reef facies developed, and these permitted an interpretation of their depositional setting in terms of a relatively distal or protected shelf. [...]
