Upper Permian to lowermost Triassic carbon isotope stratigraphy of Iranian open-marine successions

The end-Permian mass extinction is widely interpreted to have occurred in response to a carbon cycle perturbation and its environmental consequences.

Large‐Scale Coherent Southward Displacement of the Indochina Block: Constraints From New Late Cretaceous Paleomagnetic Studies

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract To better constrain the post‐collisional southward displacement of the Indochina Block (ICB) and the crustal deformation of the southeastern Tibetan Plateau, we present a reliable paleomagnetic study of Upper Cretaceous Nanxin Formation redbeds exposed in the Lanping area, at the northern edge of the Lanping‐Simao Terrane (LST).

Observations on the Upper Permian of Wegener Halvø, East Greenland

Rapport Grønlands Geologiske Undersøgelse, 1979
The Upper Permian sediments of East Greenland are exposed from Scoresby Land in the south to Clavering Ø in the north (fig. 30). The deposits on Wegener Halvø appear to be situated on the eastern side of the southern end of an elongated, approximately 80 km wide, sedimentary basin (Birkelund & Perch-Nielsen, 1976).

New constraints on the Upper Permian and Lower Triassic geomagnetic polarity timescale from the Abadeh section (central Iran)

, 2000
International audienceWe present the magnetostratigraphy of the Abadeh section (central Iran). Thermal demagnetization shows two magnetic components: one at low unblocking temperatures, which corresponds to a present day-field direction, and another at ...

A New Physics‐Constrained Neural Network Approach to Retrieve CH4 Vertical Profiles From Hyperspectral Infrared Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Methane (CH4 ${\text{CH}}_{4}$) is a critical greenhouse gas, and accurate monitoring of its vertical distribution is essential for understanding its radiative impact and identifying emission sources. This paper introduces a novel methodology using a physics‐constrained neural network based on soft constraints to retrieve CH4 ${\text{CH}}_{4}$

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, Volume 309, Issue 11, Page 3187-3217, November 2026.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

The Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

The Middle and Upper Permian deposits in Gorski Kotar: facts and misconceptions

Geologia Croatica, 1997
The frequent occurrence of sandstones and other coarse-grained sedimentary rocks in Gorski Kotar indicates molasse-type sedimentation as a consequence of the intensive erosion of an uplifted terrain in a tectonically active area. The indirect assumptions indicate that the age of the Gorski Kotar Palaeozoic complex, with the exception of a limited ...
