Arc Splitting and Back‐Arc Spreading Evolution: The Control of Slab Dehydration and Melting Processes

Geochemistry, Geophysics, Geosystems
Subduction zones are integral to Earth's deep water cycle, influencing magmatism, lithosphere dynamics and seismicity. They often exhibit development of extensional processes in the upper plate, which may lead to volcanic arc splitting and backarc basin ...

Influence of TiC and TiN Ceramic Reinforcements on the Microstructure, Thermal Expansion Behavior, and Tensile Properties of Invar 36 Manufactured by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Emplacement of the Argyle diamond deposit into an ancient rift zone triggered by supercontinent breakup

Nature Communications, 2023
Argyle is the world’s largest source of natural diamonds, yet one of only a few economic deposits hosted in a Paleoproterozoic orogen. The geodynamic triggers responsible for its alkaline ultramafic volcanic host are unknown. Here we show, using U-Pb and

The impact of planetary waves on the latitudinal displacement of sudden stratospheric warmings [PDF]

, 2013
The Northern Hemispheric winter is disturbed by large scale variability mainly caused by Planetary Waves (PWs), which interact with the mean flow and thus result in Sudden Stratospheric Warmings (SSWs).
