Depositional Interplay Between the Ancestral Rocky Mountains and Ouachita–Marathon–Sonora Orogenies: Insights From Provenance Records in the Late Palaeozoic Marfa Basin, West Texas, USA

Basin Research, Volume 38, Issue 2, March/April 2026.
Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

Geostandards and Geoanalytical Research, Volume 50, Issue 1, Page 181-199, March 2026.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 389-404, March 2026.
Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to

Braincase anatomy and palaeoneurology of Venetoraptor gassenae, a lagerpetid pterosauromorph from the Late Triassic of southern Brazil

Palaeontology, Volume 69, Issue 2, March/April 2026.
Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by

New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.
