Tectonics, Volume 45, Issue 9, September 2026.Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

Restoration Ecology, Volume 34, Issue 7, September 2026.Abstract Introduction Silicate rock powder (SRP), a slow‐release mineral additive, is increasingly used as a potential mitigation measure against soil acidification in natural areas. SRP addition has led to a higher soil base saturation and small increases in soil nutrient availability.

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.
