Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract In addition to high‐temperature vents, lower‐temperature flow (LTF) (<300°C) is abundant along mid‐ocean ridges and contributes globally‐important fluxes of heat and water along with largely‐unconstrained geochemical influences on the ocean. We examined the impact of on‐axis LTF on the chemical composition of the overlying water column (<40 m ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...

Workshop on Magmatic Processes of Early Planetary Crusts: Magma Oceans and Stratiform Layered Intrusions [PDF]
The significance of the lunar highland pristine cumulate samples were reevaluated with the aid of the additional insights provided by geologically constrained terrestrial investigations.

Tectonics of some Amazonian greenstone belts [PDF]
Greenstone belts exposed amid gneisses, granitoid rocks, and less abundant granulites along the northern and eastern margins of the Amazonian Craton yield Trans-Amazonican metamorphic ages of 2.0-2.1 Ga.

Литосфера, 2016 Xenoliths in the Early Cretaceous alkali basalts of Makhtesh Ramon basin (southern Israel) are represented by essentially olivine rocks: dunite (usually including clinopyroxen) - 5% of the total amount, lherzolite - 21%, wehrlite - 28%, clinopyroxenite -

The Wisconsin magmatic terrane: An Early Proterozoic greenstone-granite terrane formed by plate tectonic processes [PDF]
The Wisconsin magmatic terrane (WMT) is an east trending belt of dominantly volcanic-plutonic complexes of Early Proterozoic age (approx. 1850 m.y.) that lies to the south of the Archean rocks and Early Proterozoic epicratonic sequence (Marquette Range ...

An evaluation of thematic mapper simulator data for the geobotanical discrimination of rock types in Southwest Oregon [PDF]
Rock type identification may be assisted by the use of remote sensing of associated vegetation, particularly in areas of dense vegetative cover where surface materials are not imaged directly by the sensor.

Workshop on a Cross Section of Archean Crust [PDF]
Various topics relevant to crustal genesis, especially the relationship between Archean low - and high-grade terrains, were discussed. The central Superior Province of the Canadian Shield was studied.
