Upper Kellwasser carbon isotope excursion pre-dates the F–F boundary in the Upper Devonian Lennard shelf carbonate system, Canning Basin, Western Australia [PDF]

, 2015
Here we report four high-resolution carbon isotope records in addition to trace element data for the Frasnian–Famennian (F–F) boundary interval in the Lennard Shelf carbonate system of the Canning Basin, Western Australia.

The outcrop of the Middle Ordovician (Darriwilian stage) and Upper Devonian (Frasnian stage) Yakhnovo as a unique geological feature in the East of the Main Devonian Field

Vestnik MGTU
At present, within the Baltic-Ladoga structural-facies zone characterized by the distribution of coastal-marine and coastal-continental deposits of the Lower and Middle Frasnian outcrops of bedrock are practically lost.

High-Resolution Late Devonian Magnetostratigraphy From the Canning Basin, Western Australia: A Re-Evaluation

Frontiers in Earth Science, 2021
Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.

The Frasnian deposits in the Bol’shaya Nadota River region (Sub-Polar Urals) - stratigraphy and depositional enviroment

Литосфера, 2016
The main features of the Givetian-Frasnian shoal deposits of the Sub-Polar Urals (Matyashor formation) are considered. The study part of the section corresponds to varcus - rhenana zones on the basis of conodonts.

Sediment‐stressed reefs over the past 420 Myr

The Depositional Record, Volume 12, Issue 1, February 2026.
In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Neverovsky Palaeoreef and Associated Deep-Marine Facies: High-Value Late Devonian Geoheritage from the Rudny Altai

Heritage
The Rudny Altai is a western segment of the Altai orogenic belt. Its geological richness makes its geoheritage exploration an urgent matter. Investigations in the Loktevsky District (Altai Region, Russian Federation) have led to the finding of three ...
