A database of detrital zircon U–Pb ages and Hf isotopes for the Middle East (Iranian and Arabian plates)

Geoscience Data Journal
The detrital zircon records significant information in the ‘source‐sink’ system. With the application of in situ laser ablation technology, a large number of high‐quality detrital zircon data have been published since 2000.

Something Old, Something New: Revisiting Terranes of the Western Paleozoic and Triassic Belt, Klamath Mountains, Northern California

Geosciences
The age, provenance, and evolution of some terranes in the Klamath Mountains are poorly constrained because of low detrital zircon yields. We present petrography and 947 new detrital and igneous zircon U-Pb ages from the North Fork (NFT), Eastern Hayfork

Ediacaran–Cambrian High‐Strain Melt‐Present Deformation of the Archean Charcot Province, East Antarctica

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The assembly of Gondwana involved several Pan‐African orogens, although their extension into ice‐covered Antarctica remains contentious. Particularly problematic is our understanding of the Kuunga orogenic system in East Antarctica, including its eroded architecture and temporal evolution. The remote Charcot Province, at the easternmost extent

Longevity and Reactivation of Intracontinental Walled Basins: Thermochronologic Evidence From Western Mongolia

Basin Research, Volume 38, Issue 4, July–August 2026.
Permian–Jurassic tectonism produced cooling ages preserved in Mesozoic strata of the Dzereg and Dariv basins. Thermal modeling indicates mid‐Cretaceous and late Cenozoic basin inversion and cooling synchronous with bounding‐range exhumation, supporting a long‐lived source‐to‐sink relationship and persistent inherited relief since the Jurassic ...

Thermal and Structural Reconstruction of an Eroded Foreland Basin: Central Appalachian Basin, USA

Basin Research, Volume 38, Issue 4, July–August 2026.
New low‐temperature thermochronology and modelling reveal a complex thermal history for the central Appalachian Basin. Results indicate Carboniferous exhumation of the fold‐thrust belt and Mesozoic heating in the foredeep linked to the Rome Trough. Deeply buried Devonian source rocks were consequently pushed past the peak oil and gas windows.

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, Volume 73, Issue 5, Page 1631-1663, August 2026.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

Sedimentology, Volume 73, Issue 5, Page 1842-1866, August 2026.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

A synthesis of available detrital zircon data from Turkey, Cyprus and Greek peninsula

Geoscience Data Journal
This paper describes the assembly of an updated dataset of detrital zircon geochronology and Lu–Hf isotopes for Turkey, Cyprus and Greek peninsula. This first version of the dataset documented 286 samples with detrital zircon U–Pb data and 70 samples ...
