An organic geochemical investigation combined with sequence stratigraphy was performed in the Ceará Basin, an offshore basin located Northeastern Brazil. The information available from 30 well logs (gamma-ray, resistivity, density), besides (TOC, and pyrolysis indexes) isotopic (?13C) data, aided preparation of a dataset for this study. application sequence-stratigraphic methods helped classify...

Abstract In the Alpstein massif of north-eastern Switzerland, a complete succession uppermost Hauterivian to Barremian condensed hemipelagic sediments crops out. This is known as Tierwis Formation, comprising in ascending order, Altmann and Drusberg members. The sedimentary bears number fossiliferous glauconite- or phosphate-rich beds. A large newly discovered ammonites from these key beds seve...

Abstract Despite the previous interpretations of evolutionary scenarios Qatar Arch, present study aimed to a new complementary scenario lay out probable effects another basement fault, corresponding physical shape Arch. A remote sensing was carried based on geological and geophysical data interpretations, obtained from some national international databases, including GIS-based global geology Ha...

New material of an iguanodontid styracosternan ornithopod from the Lower Cretaceous Iberian Peninsula is described. The cranial and postcranial skeletal remains are Barranco del Hocino-1 site. These fossils (Iguanodontidae sensu Xu et al., 2018) represent first medium-sized Upper Sequence Blesa Formation (Barremian). new characterized by a unique combination characters that suggest they corresp...

The Aptian sedimentary deposits of the Castro Urdiales area in north Spain record an episode disoxia/anoxia which postdates Oceanic Anoxic Event 1a (OAE 1a). Carbonate platform and overlying facies are analysed for stratigraphy, sedimentology, total organic carbon isotopes. Lower shallow-water limestones covered by deeper-water marlstones organic-carbon-rich black lutites lower to upper Aptian,...
