Geological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Journal of Quaternary Science, Volume 41, Issue 4, Page 645-659, May 2026.ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

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.

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...

Effect of Composition on Grain‐Boundary Chemistry and Fracture Behavior in High‐Entropy Carbides
Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.ABSTRACT High‐entropy carbides (HECs) are often treated as a single material class defined by configurational entropy; however, their properties are governed by composition‐specific defects and grain‐boundary chemistry. This study demonstrates that substituting a single element can qualitatively change grain‐boundary structure and fracture behavior in ...

Ryugu reference project: Recommendations from the measurement definition team
Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,
