Microfacies and Depositional Conditions of Jurassic to Eocene Carbonates: Implication on Ionian Basin Evolution

open access: yesGeosciences, 2021
In order to decipher the paleo-depositional environments, during the Late Jurassic to Early Eocene syn-rift stage, at the margins of the Ionian basin, two different areas with exposed long sequences have been selected, Kastos Island (external margin) and

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

open access: yes, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

open access: yes, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

Pararhabdodon Isonensis and Tsintaosaurus Spinorhinus: A New Clade of Lambeosaurine Hadrosaurids from Eurasia [PDF]

open access: yes, 2009
We present new anatomical information showing that Koutalisaurus kohlerorum, from the Maastrichtian of Lleida Province, northeastern Spain, is most probably the junior synonym of Pararhabdodon isonensis from the same region.

Scientific Drilling of the Terrestrial Cretaceous Songliao Basin [PDF]

open access: yesScientific Drilling, 2008
Investigations of critical climate changes during the Cretaceous have the potential to enhance our understanding of modern global warming because the extreme variances are the best-known and most recent example of a greenhouse Earth (Bice et al., 2006 ...
