Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes
Communications Earth & EnvironmentSubduction initiation remains elusive because no present example exists. Ophiolites formed over nascent subduction zones in the past provide the key to constraining the processes of subduction initiation.

SECONDARY PLATINUM-GROUP MINERALS FROM A PLACER OF THE BOLSHOY SAP RIVER (CENTRAL URALS) [PDF]
МинералогияThe object of the present study includes grains of platinum-group minerals (PGMs) from a concentrate, which was obtained during mining of a technogenic gold placer near the Pervomaisky duniteharzburgite massif (Central Urals).

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.

Linking rock fabric to fibrous mineralisation: a basic tool for the asbestos hazard [PDF]
, 2011 In recent years, many studies have addressed the effect on human health caused by asbestos exposures. As asbestos is a group of fibrous minerals that mainly occurs in mafic and ultramafic rocks (ophiolitic sequences), a close relationship between ...

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.
