Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, EarlyView.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Major elements geochemistry of chlorite in different ore deposits and its genesis and exploration significance: a case study from Naruo porphyry Cu deposit in Duolong ore district, Tibet

open access: yesFrontiers in Earth Science
Chlorite is present extensively in many types of deposits. The mechanism underlying the chemical variations in chlorite remains unclear. The Naruo porphyry deposit is a giant copper porphyry deposit in the Duolong ore district of Tibet.

Tailoring Defective Tungsten Oxide Aerogel Evaporator for Enhanced Solar Steam Generation and Heavy Metal Adsorption Toward Agricultural Irrigation

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
A cost‐effective defective WO3−x@cellulose aerogel composites that simultaneously convert wastewater into agricultural irrigation water through solar‐driven freshwater generation and heavy metal remediation was proposed. And the precision defect engineering of oxygen‐vacancy modulated WO3−x nanocrystals demonstrate excellent solar absorption efficiency

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 4, Page 265-286, May 2026.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

CULTURAL FUSION IN LATE BRONZE AGE GOLDWORK: DIADEMS AND MOUTH‐PIECES FROM HALA SULTAN TEKKE, CYPRUS

open access: yesOxford Journal of Archaeology, Volume 45, Issue 2, Page 151-179, May 2026.
Summary This study investigates recently discovered gold diadems and mouth‐pieces from seven chamber tombs and one shaft tomb at the Late Bronze Age cemetery of Hala Sultan Tekke, dating from the fifteenth to the thirteenth centuries BC. The chamber tombs, all containing multi‐generational burials, yielded a variety of ornaments, which are analysed in ...

ENSO‐Mediated Linkage Between the East Asian Summer Monsoon and Cordilleran Ice Sheet Discharge During MIS 3

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)
