Unveiling of a trans-oceanic arc system diachronous initiation: Easternmost Neo-Tethyan intra-oceanic subduction record from Bornean peridotite

This study identifies geochemically distinct mantle suites in the Meratus Complex of southeastern Borneo as evidence for the easternmost, diachronous initiation of a trans-oceanic intra-oceanic subduction system in the Neo-Tethys, which evolved from an abyssal to a mature fore-arc setting and formed a >8,000-km arc system by the Late Cretaceous.

Wood Quality and Climatic drivers of Chestnut Tree Growth (Castanea sativa Mill.) and Canopy Stress in Central Italian Coppices

This study on a 37-year-old chestnut coppice in central Italy reveals that wood quality is compromised by basal decay and that radial growth is significantly limited by late-summer drought, highlighting the need for timely silvicultural interventions to mitigate the combined effects of climate stress, pathogens, and aging stands.

Fault segment linkage and reactivation drive localized tectonic inversion in the Exmouth Plateau, NW Shelf Australia

This study demonstrates that localized tectonic inversion in the Exmouth Plateau is driven not merely by far-field compression but by the selective reactivation and linkage of inherited segmented fault architectures, which modulate strain partitioning and create specific sites for contractional deformation.

Experimental Investigation of Dike Propagation Influenced by Graben Topography and Magma Viscosity Using Analog Modeling

This study utilizes analog modeling to demonstrate that dike propagation and volcanic vent locations in graben settings are controlled by the interplay between magma viscosity, topographic stress fields, and crustal mechanical layering, which collectively determine whether intrusions arrest, transition between geometries, or reach the surface.

Boundary layer wind turning and cross-isobaric mass flux from an idealised single column model framework perspective

Using an idealized single-column model framework inspired by GABLS1, this study identifies wind speed, roughness length, and ABL thickness as key controls on boundary layer wind turning and cross-isobaric mass flux, revealing that systematic differences in vertical resolution and turbulence closure schemes—particularly under near-neutral mid-latitude conditions—help explain discrepancies between state-of-the-art models and observations.
