Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.

Chromite in the mantle section of the Oman Ophiolite: Implications for the tectonic evolution of the Oman Ophiolite [PDF]
, 2015 Chromite in the Oman ophiolite is located in the mantle section of the ophiolite sequence and forms abundant small podiformdeposits throughout the length of the ophiolite (Rollinson, 2005).The Oman ophiolite has an exposed mantle section of ca 10 000 km2,

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Hornblendite in the Lower Crust: A Possible Source for Porphyry Cu Deposits
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Lower crustal sulfide‐bearing Cu‐rich cumulates, mainly occurring as hornblendite, have been proposed as a critical source component for the development of giant porphyry Cu deposits (PCDs); however, their mineralogical and geochemical nature remain elusive.
