Stratigraphy, facies and geodynamic settings of Jurassic formations in the Bükk Mountains, North Hungary: its relations with the other areas of the Neotethyan realm. [PDF]

open access: yes, 2013
Jurassic mélange complexes related to the subduction of the Neotethys Ocean occur in the Bükk Mountains, North Hungary. This paper characterizes the sedimentary sequence of basin and slope facies that occur in the southwestern part of the Bükk ...

Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

open access: yesThe Depositional Record, Volume 11, Issue 2, Page 537-564, April 2025.
Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

Integrated bio- and cyclostratigraphy of Middle Triassic (Anisian) ramp deposits, NW Bulgaria

open access: yesGeologica Carpathica, 2019
A cyclostratigraphic interpretation of peritidal to shallow-marine ramp deposits of the early Middle Triassic (Anisian) Opletnya Member exposed in outcrops along the Iskar River gorge, NW Bulgaria, is presented.

Nuevos enfoques sobre los vertebrados del Pérmico y Triásico de la Península Ibérica, con énfasis en las cuencas Pirenaica y Catalana [PDF]

open access: yes
Few studies paid attention to the Permian and Triassic vertebrates from the Iberian Peninsula and a re-evaluation of these faunas is needed in order to compare them with other European basins.

Magnetobiostratigraphy of the Spathian to Anisian (Lower to Middle Triassic) Kçira section, Albania [PDF]

open access: yes, 1996
Magnetobiostratigraphic data are presented from three Early/Middle Triassic Han-Bulog Limestone successions from Kçira, northern Albania. A total of 206 standard palaeomagnetic samples were obtained for thermal demagnetization and statisticalanalysis ...

Smithian–Spathian carbonate geochemistry in the northern Thaynes Group influenced by multiple styles of diagenesis

open access: yesThe Depositional Record, Volume 11, Issue 2, Page 616-636, April 2025.
While the Smithian–Spathian boundary carbon isotopic excursion has been traditionally interpreted as capturing global carbon cycle behaviour, recent studies have suggested that at least some Early Triassic carbon isotopic excursions may incorporate influences from authigenic or early diagenetic processes.

NEW DASYCLADAL ALGAE FROM THE ANISIAN (MIDDLE TRIASSIC) OF LIKA (CROATIA)

open access: yesRudarsko-geološko-naftni Zbornik
Two new species of dasycladal algae are described from the Anisian limestones of the Lika region in Croatia. Griphoporella? speleoluka n. sp. is characterized by very small cylindrical thallus and vesiculiform laterals arranged in close whorls.

The neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar

open access: yesPapers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract The enigmatic neodiapsid Thadeosaurus colcanapi (Lower Sakamena Formation, southwestern Madagascar), sole species of the genus Thadeosaurus, is revised here. The attribution of 12 of the 21 referred specimens is confirmed, spanning all ontogenetic stages, and the anatomy of Thadeosaurus is redescribed in detail with comments on ontogenetical ...

Origin of ferruginous coated grains in the Lower Jurassic palustrine limestones of the Pranhita–Godavari Basin, India

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 44-69, February 2025.
In this article, we have proposed a model for the origin of ferruginous coated grains in a continental rift setting. The association of these iron coated grains with limestones and sub‐aerially weathered microbialites have made them suitable for a comparative assessment of various hypotheses of solute supply and precipitation, which can be relevant for

OLENEKIAN TO EARLY LADINIAN STRATIGRAPHY OF THE WESTERN PART OF THE AGHDARBAND WINDOW (KOPEH-DAG, NE IRAN)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
The structural setting and the stratigraphy of the Early to Middle Triassic sedimentary succession exposed in the western part of the Aghdarband window (Kopeh Dag, NE Iran) is described. Six stratigraphic sections in the Sefid-Kuh Limestone, Nazar-Kardeh
