Palaeobiogeographical constraints on the distribution of foraminifers and rugose corals in the Carboniferous Tindouf Basin, South Morocco

Journal of Palaeogeography, 2013
The northern flank of the Tindouf Syncline in southern Morocco exhibits a continuous, well exposed Carboniferous succession with limestones of Late Asbian to Early Bashkirian age containing rich and diverse foraminiferal and rugose coral assemblages ...

Biostratigraphy and palaeoecology of marine microphytoplankton cysts from Member 4 of the Mila Formation, Mila Kuh, eastern Alborz [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2019
Well preserved and diverse organic-walled marine microphytoplankton cysts (acritarchs sensu lato) occur in Member 4 (comprising mostly of fine-grained clastics with thin carbonate intercalations) of the Mila Formation at the type section, southwestern ...

Geochemistry of metasedimentary rocks from the Eastern Pyrenees (Iberian Peninsula): Implications for correlation of Ediacaran terranes along the Gondwanan margin

, 2023
The North African margin of Gondwana formed by subduction and accretion during Ediacaran to Cambrian times. Sections of this active margin were incorporated during the late Paleozoic to the Variscan and Appalachian orogens.

The appearance of Rosenella (stromatoporoid sponge) in Baltica: new species from the Pirgu Stage (Katian, Upper Ordovician) of Estonia [PDF]

Estonian Journal of Earth Sciences
The Katian Age, part of the Late Ordovician Epoch, was a period of significant stromatoporoid diversification. However, their fossil record is often less continuous, hindering our understanding of their diversity and diversification.

Banded amphibolites in the Alps: a new interpretation in relation to early Paleozoic peraluminous magmatism

Swiss Journal of Geosciences, 2020
The Strona-Ceneri Zone is located south of the Insubric line, where Alpine overprint is mainly brittle and of low grade or even absent. Apart from the unmetamorphic Permo-Carboniferous sediments and intrusiva the Strona-Ceneri Zone is an Ordovician ...

A unique occurrence of a psammosteid heterostracan on the peri-Gondwanan shelf in the Lower/Middle Devonian boundary marine deposits [PDF]

Fossil Imprint, 2016
A rare psammosteid heterostracan (Agnatha) occurrence in the Devonian of the Prague Basin is indicative of a dry land influence in the regional palaeogeography. This argument is strongly supported by the appearance of vascular plants, but the studied vertebrates allow us to presume a local brackish water environment.

Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

Monazite and Xenotime U‐Pb Geochronology and Thermometry of the Blue Ridge and Inner Piedmont of North Carolina: Implications for the Thermal‐Metamorphic Evolution of the Southern Appalachian Metamorphic “Core”

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The southern Appalachian orogen preserves a complex distribution of metamorphism and deformation varying in timing, magnitude, and spatial extent. These complexities give rise to disparate interpretations for southern Appalachian tectonic evolution, which complicates the testing and interpretation of tectonic models in this system.
