Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, Volume 68, Issue 5, Page 1022-1036, October 2026.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Visualizing Reversible Uranyl (UO22+) Capture and Release With Self‐Indicating Porous Organic Polymers [PDF]

Small Sci
Uranium capture from seawater is a promising sustainable strategy, and the adsorbents showing high uptake capacity and sorption trackability are essential. The work describes self‐indicating porous organic polymers that exhibit visible color changes during uranium adsorption and desorption cycles allow tracking of uranium‐free, saturated states without

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, Volume 68, Issue 5, Page 1050-1061, October 2026.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).
