Late Carboniferous Paleomagnetism From North Qiangtang Block Reveals a Multibranched Paleo‐Tethys Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

The asbian to arnsbergian conodonts and sequence stratigraphy of the Northumberland trough [PDF]

open access: yes, 2001
Yoredale sequences are excellent exemplars of the sequence stratigraphy model; the spacial and temporal variation of these complex shallow marine/fluvio-deltaic/ coastal plain cycles, exhibit all the uiternal facies architecture that would be expected of

Basement Geometry and Cover‐Basement Relationships in the Central‐Western Jaca‐Pamplona Basin (Southern Pyrenees): Along‐Strike Variations and Role of Structural Inheritance

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract This study presents a detailed, geometrical characterization of the central‐western domain of the Jaca‐Pamplona Basin based on a combined interpretation of seismic and surface data and the construction of four serial cross‐sections. For the studied portion of the basin, our results highlight that the basement is notably folded and faulted and ...

FORAMINIFERAL TIMING OF CARBONATE DEPOSITION ON THE LATE DEVONIAN (FAMENNIAN)-MIDDLE PENNSYLVANIAN (BASHKIRIAN) TENGIZ PLATFORM, KAZAKHSTAN

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2003
Calcareous foraminifers provide a time-stratigraphic framework to chronicle the development of the Tengiz carbonate platform that thrived from the latest Devonian (late Famennian) into the Middle Pennsylvanian (late Bashkirian).  Correlative zones, based

Microbially induced sedimentary structures in fluvial settings: the gas domes from the Bolzano Megacaldera (Permian, Italy)

open access: yesSedimentology, Volume 73, Issue 4, Page 914-944, June 2026.
ABSTRACT Gas domes serve as some of the earliest and most persisting indicators of life on Earth, yet their documentation in continental environments remains sparse. This study aims to bridge this gap by examining gas domes within the Permian fluvial succession of Monte Luco, located in the caldera of the Bolzano Supervolcano. These structures occur as
