Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Deformation of the Upper Oceanic Crust in the Outer Rise of the Sumatra Subduction Zone: Insights From P‐ and Doubly Converted S‐Wave Arrivals on Downward Continued Streamer Data

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...

Lithofacies, petrography, and geochemistry of the Lamphun oceanic plate stratigraphy: As a record of the subduction history of Paleo-Tethys in Chiang Mai-Chiang Rai Suture Zone of Thailand

Open Geosciences
The Mélange in Lamphun Province, situated in the southern region of the Chiang Mai-Chiang Rai Suture Zone (CMCRSZ), remains inadequately explored. This study employs field investigations and petrographic analysis to delineate the characteristics of the ...

Chrome spinel compositions as evidence for an Archaean ophiolite in the Kuhmo greenstone belt in Finland [PDF]

Bulletin of the Geological Society of Finland, 1994
Investigations into chromite compositions in Archaean ultramafic rocks are rare. Most Archaean ultramafic rocks have undergone a multi-stage history of deformation and metamorphism, and therefore fresh primary chromite is rarely preserved.

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...
