Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Provenance Analysis Based on Cluster In‐Betweenness and Support Vector Machines: Identifying Migrant Candidates Using Multi‐Isotope Fingerprints

Archaeometry, Volume 68, Issue 4, Page 607-619, August 2026.
ABSTRACT Provenance reconstruction using strontium and lead stable isotopes can produce complex multidimensional fingerprints, challenging traditional methods. Identifying nonlocals, who migrated between sites, is a major task. Migrants are identifiable by divergent multi‐isotope fingerprints due to isotopic mixing between origin and destination sites.

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, Volume 68, Issue 4, Page 818-830, August 2026.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Synthetic Seismic Data Generation for Deep Learning Segmentation of Clinoforms: Integrating Process‐Based Forward Stratigraphic Modelling and Ray‐Based Seismic Modelling

Basin Research, Volume 38, Issue 4, July–August 2026.
This study aims to develop a deep learning model for automated clinoform segmentation. The trained model achieved high segmentation performance on a synthetic testing dataset and successfully generalised to real seismic profiles. The proposed approach demonstrates the effectiveness of using forward stratigraphic modelling and point spread function for ...

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

Sedimentology, Volume 73, Issue 5, Page 1403-1420, August 2026.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, Volume 73, Issue 5, Page 1421-1434, August 2026.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

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.

Substantial Accumulation of Chemically Oxidizable Organic Carbon in Continental Margin Sediments

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The balance between organic carbon (OC) sequestration and oxidation regulates the oceanic carbon cycle, and OC reactivity determines its susceptibility to remineralization or long‐term burial. However, the stability of sedimentary OC on continental margins remains poorly understood.
