Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Microbial communities are strongly controlled by local nutrient availability, frequently resulting from mineral weathering and erosion. On Earth, basaltic rocks in habitable alkaline lacustrine environments are often initially colonised by ‘pioneer’ communities that induce the precipitation of fine‐scale microbial carbonate ‘coatings’; on Mars,

Tectonics, Volume 45, Issue 10, October 2026.Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.

Tectonics, Volume 45, Issue 10, October 2026.Abstract Detrital zircon U–Pb geochronology from Triassic–Jurassic basins in the New England Orogen (NEO) constrains sediment provenance and episodic continental arc evolution along the eastern Gondwanan margin. Dominant zircon clusters at 270–230 Ma and 340–300 Ma in these basins were likely sourced from contemporaneous magmatism in the NEO ...

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, Volume 68, Issue 5, Page 908-918, October 2026.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Geological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...
