The Depositional Record, Volume 12, Issue 4, September 2026.This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Global Change Biology Communications, Volume 1, Issue 3, September 2026.Multi‐stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperatures. As global and local environmental change increase compound stress events on coral reefs, distinguishing hypoxia‐driven effects and interactive stressor ...

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 ...

Calc-alkaline volcanism and the thickness of the early Precambrian crust in North America
, 1969 Geochemical and geophysical data indicate that the average potash content of young calc-alkaline volcanics increases in approximately a linear manner with crustal thickness. If such a relationship existed during the Precambrian, potash contents of early

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.

SALINE DEPOSITS AND ALKALINE MAGMAT1SM:A GENETIC MODEL [PDF]
Journal of Sciences, Islamic Republic of Iran, 1990 The temporal-spatial coincidence of saline deposits with rifting and alkaline magmatism has now become a commonly accepted fact. The congruency of these three phenomena implies logically, their trilateral genetic interrelation.

Petrogenesis of the Lalezar granitoid intrusions (Kerman Province - Iran) [PDF]
Journal of Sciences, Islamic Republic of Iran, 2015 The Lalezar granitoids crop out within volcanic successions of the Urumieh-Dokhtar Magmatic Assemblage (UDMA). These granitoids have a range from gabbro-diorites to granites in composition.

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
