FOSSILIZATION OF AMMONITES AND SEDIMENTARY EVENTS IN DEEP ENVIRONMENTS OF CARBONATE PLATFORM (HIGHEST MIDDLE TO LOWEST UPPER OXFORDIAN, IBERIAN RANGE, SPAIN)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2004
In the Ricla area (Zaragoza, Aragonese Branch of the Iberian Range), at the top of the Yátova Formation, grey-reddish wackestone limestones grade into yellow-green siliciclastic limestones of the Aldealpozo Formation.

The palaeogeographic outlines of the Caucasus in the Jurassic: The Caucasian Sea and the Neotethys Ocean [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2006
The Caucasian Sea, fringing the northern margin of the Jurassic Neotethys Ocean, largely covered the Caucasus. Continental, shallow-marine and deep-marine palaeoenvironments delineate palaeogeographic outlines for three significant time slices: the Late ...

Salt Tectonics and Inversion Style in the Southeastern Iberian Chain

open access: yesTectonics, Volume 45, Issue 11, November 2026.
Abstract The southeastern Iberian Chain is characterized by Mesozoic rift basins that were subsequently inverted during Alpine contraction. We integrate geological mapping, borehole data, balanced cross‐sections, structural restoration, and forward kinematic modeling to evaluate how rift architecture controlled Alpine deformation from basin to crustal ...

Oxygene Isotopes and climatic Control of Oxfordian Coral Reefs (Jurassic, Tethys)

open access: yes, 2010
International audienceStable isotope studies were carried out on shells of reef-dwelling brachiopods and oysters to evaluate the impact of climate changes on coral communities during the Oxfordian (Late Jurassic) in western Europe and northwestern Africa.

Multi-scale modelling of gas flow in nanoscale pore space with fractures

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2020
In this work, a multi-scale pore network with fractures is developed against experimental data in a wide range of degrees of water saturation. The pore network is constructed based on the measured microstructure information at several length scales.

On the Origin of the Tingidae (Insecta, Heteroptera)

open access: yesZoologica Scripta, Volume 55, Issue 6, Page 876-892, November 2026.
ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

A potential stratotype for the Oxfordian/ Kimmeridgian boundary: Staffin Bay, Isle of Skye, UK [PDF]

open access: yes, 2006
A coastal exposure of the Staffin Shale Formation at Flodigarry, Staffin Bay, Isle of Skye, Scotland, UK fulfils the criteria for definition as the Global Stratotype Section and Point (GSSP) for the base of the Kimmeridgian Stage (Upper Jurassic).

Looking Under the Orogenic Lid—Assessing the European Basement Beneath the Alpine Wedge by U‐Pb Zircon Geochronology

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.
