The Jurassic–Cretaceous Transition in the Slovenian Basin (Alpine Atlantic): Further Evidence for Palaeoenvironmental Record in Pelagic Sediments

Geochemistry, Geophysics, Geosystems
Over the vast area of present‐day Europe, the Tithonian–Berriasian transition was a time of climate aridization, which was supposedly related to the more general trend of the latest Jurassic–earliest Cretaceous cooling and restrictions in atmospheric ...

Paleo-Depositional Environments of Mirdita Zone During the Upper Jurassic–Lower Cretaceous

Albanian Journal of Natural and Technical Sciences
To decipher the paleo-depositional environments and the geodynamic evolution of the Mirdita Zone during the Upper Jurassic–Lower Cretaceous, as well as the timing of the emplacement of the underlying ophiolitic deposits, several areas with different ...

The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200 to ∼3,000 km. These large discrepancies stem principally from two primary

LATE JURASSIC AND EARLY CRETACEOUS AMMONITES FROM THE WEIMEI FORMATION IN GYANGZE, SOUTHERN TIBET

Rivista Italiana di Paleontologia e Stratigrafia, 2004
The Weimei Formation in southern Tibet is a shallow marine sequence accumulated in the northern margin of the Indian subcontinent. It has been dated as Tithonian based on ammonites such as Haplophylloceras strigile (Blanford), Berriasella sp.

Biostratigraphy and microfacies of the pelagic carbonate formations in the Yavorets section (Tithonian–Berriasian), Western Balkan Mts, Bulgaria

, 2019
Calpionellid study has provided new evidence of early and late Tithonian age of the top of the Gintsi Formation, and of late Tithonian and early Berriasian age of the Glozhene Formation in the Yavorets section (Western Balkan Mts, Bulgaria).

Aptychi from the Berriasian/Valanginian (France and Spain) : new stratigraphical and morphological details [PDF]

, 2016
Late Berriasian–earliest Valanginian lamellaptychi (Cephalopoda) are described in detail for the first time. With one exception, all species belong to early representatives of Mortilletilamellaptychus. The majority of the well dated aptychi come from the

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

New crustacean microcoprolites from the Lower Cretaceous (middle Berriasian-lower Valanginian) of the Neuquén Basin, Southern Mendoza, Argentina [PDF]

, 2010
Three new ichnotaxa of crustacean microcoprolites from the Neuquén Basin, Argentina, are described in this paper: Palaxius rahuensis Kietzmann n. isp. (early Valanginian), Palaxius mendozaensis Kietzmann n. isp. and Palaxius malarguensis Kietzmann n. isp.
