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 ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Литосфера, 2016 We present for the first time U-Pb age data and Hf-Nd-Sr-Cu-S isotope signatures for lithologies and associated sulphide ores from the Binyuda and Dyumtaley ultramafic-mafic intrusions located in the limits of the Taimyr Peninsula (Russian Arctic ...

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Cryptic Superfine Placer Gold Populations, Round Hill Mine, Southern New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.Superfine (50–<1 µm) detrital gold and platinum group mineral (PGM) particles at the Round Hill mine near Foveaux Strait were locally derived (<20 km) from as‐yet undefined basement sources. This superfine component contrasts with the dominant coarser (typically >100 µm) gold and PGM particles at the mine that have been transported for >100 km in ...

ChemistrySelect, Volume 11, Issue 33, 1 September 2026.Microwave‐assisted hydrothermal synthesis produces CeVO4/g‐C3N4 heterostructures with enhanced solar‐simulated‐light photocatalytic activity. Efficient degradation of Rhodamine B and Methylene Blue is achieved through improved charge separation and reactive oxygen species generation, highlighting an ecofriendly strategy for environmental remediation ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The anatomy of orogens is difficult to decipher as structural information is usually limited to surface and seismic data. Seismic properties are directionally dependent on anisotropic minerals, especially phyllosilicates. Due to tectonic complexity, the effect of anisotropy in seismic data is difficult to determine.
