Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Magnetic Reversals During the Deccan Volcanism: Paleomagnetic Insights From the Pachmarhi Dykes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The three main dyke swarms that are linked to the Deccan Continental Flood Basalts are the Nasik‐Pune, Western Coastal, and Narmada‐Satpura‐Tapi (N‐S‐T) swarms. Encompassing approximately 244 mapped basaltic dykes, mainly trending E‐W and positioned along an ancient tectonic zone, the Pachmarhi dyke swarm is situated in the eastern N‐S‐T ...

Electron Spin Resonance Thermochronometry Indicates Quaternary Activity of the Brenner Fault (Eastern Alps)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Brenner Fault is one of the most important normal faults in the Eastern Alps as it accommodates uplift and lateral extrusion of the Tauern Window. Consequently, understanding its kinematic history is important for studying the dynamics of the Eastern Alps, in particular the Tauern Window.

Rapid Slab Rollback Drives Early Cretaceous Back‐Arc Extension in NE China: Implication for Crustal Growth and Episodic Porphyry Mineralization

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Eocene Lamproitic Magmatism in Gangdese: Melting Sub‐Arc Lithospheric Mantle and Implications for the Early Cenozoic Magmatic “Flare Up” in Southern Tibet

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).

Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined. We present new geochemical data from the middle crust of the Kohistan Arc and use existing geochemical and geochronological literature data from this arc to ...

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

Tectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

A database of detrital zircon U–Pb ages in the North China Craton from the Paleoproterozoic to the early Palaeozoic

Geoscience Data Journal
U–Pb dating of detrital zircon is widely used in geology to identify the source of sediments and constrain palaeogeography and tectonic history. We collected the detrital zircon from the Paleoproterozoic to early Palaeozoic strata to understand the North

Slumping and Sediment Storage at the Shelf‐Edge: A Case Study From the Kookfontein and Waterford Formations, Tanqua Karoo Depocenter, South Africa

Basin Research, Volume 38, Issue 2, March/April 2026.
Block model of Tanqua shelf‐edge delta formation at Katjiesberg, illustrating key stratigraphic features and system relationships interpreted from the Kookfontein‐Waterford formations. Schematic lines A‐E correspond to locations of measured sections. ABSTRACT A low‐gradient shelf‐edge delta system preserved at the Katjiesberg outcrop in the northern ...
