Lower crustal zircons reveal Neogene metamorphism beneaththe Pannonian Basin (Hungary)

Open Geosciences, 2015
Neogene alkaline intraplate volcanic depositsin the Pannonian Basin (Hungary) contain many lowercrustal granulite-facies xenoliths. U-Pb ages have been determinedfor zircons separated from a metasedimentaryxenolith, using LA-ICPMS and SHRIMP techniques ...

Deep crustal electromagnetic structure of Bhuj earthquake region (India) and its implications [PDF]

, 2010
The existence of fluids and partial melt in the lower crust of the seismically active Kutch rift basin (on the western continental margin of India) owing to underplating has been proposed in previous geological and geophysical studies. This hypothesis is

IODP Expeditions 304 & 305 Characterize the Lithology, Structure, and Alteration of an Oceanic Core Complex [PDF]

Scientific Drilling, 2006
More than forty years after the Mohole Project (Bascom, 1961), the goal of drilling a complete section through in situ oceanic crust remains unachieved.

Images of Early Continental Breakup in and around the Gulf of California and the Role of Basal Shear in Producing Wide Plate Boundaries [PDF]

, 2004
Active faulting in the northern Gulf of California occurs over a broad zone, 70 x 200 km, affecting two-thirds of the width of new crust that has formed there starting at 6 Ma.

Stealth Metasomatism in Granulites from Ivrea (NW Italy): Hydration of the (Variscan) Lower Crust by Melt Flow

Geosciences
Granulites and associated dykes from the less well-studied southern Ivrea–Verbano Zone (around Ivrea town) are characterized by combining field, macro, micro and chemical (major and trace-element mineral composition) data to identify chemical and ...

Characteristics and consequences of flow in the lower crust [PDF]

Journal of Geophysical Research: Solid Earth, 2000
In some places, there is strong evidence that the lower continental crust has flowed so as to smooth out variations in crustal thickness caused by differential crustal extension or shortening. In order to better understand the processes involved, we investigate the behavior of a fluid layer over a fluid half‐space to see how such a system responds to ...

Lower Crust Viscosity in Central Tibet Inferred From InSAR Derived Deformation Around Siling Co Lake After Its Rapid Expansion in the 2000s

Geophysical Research Letters, 2023
Constraining the lithospheric rheology of Tibetan Plateau is important for the physical understanding of its tectonics. Siling Co, the largest high‐altitude lake in the world, has experienced a rapid water level increase in the 2000s.

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

Advanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...
