Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Pegmatites of the Mokromoskovsk granite pluton

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Introduction. The Mokromoskovsky pluton is composed of light gray granites and dark gray granodiorites. Light gray granites are composed of oligoclase (35-40%), microcline (20-25%), quartz (30-35%), and biotite (2-5%).

Microstructural Controls on Geothermal Reservoir Host Rock Responses to Elevated Pressures and Temperatures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rock microstructure controls geothermal fluid flow within reservoirs hosted in active volcanic environments and as such it is necessary to constrain the microstructural evolution of rocks at elevated pressure and temperature conditions. Despite Andean geothermal systems hosting numerous high enthalpy geothermal plays, there remains a paucity ...

Optimal Location of Vanadium in Muscovite and Its Geometrical and Electronic Properties by DFT Calculation

, 2017
Vanadium-bearing muscovite is the most valuable component of stone coal, which is a unique source of vanadium manufacture in China. Numbers of experimental studies have been carried out to destroy the carrier muscovite’s structure for efficient ...

Thermal structure and exhumation history of the Lesser Himalaya in central Nepal [PDF]

, 2004
The Lesser Himalaya (LH) consists of metasedimentary rocks that have been scrapped off from the underthrusting Indian crust and accreted to the mountain range over the last ~20 Myr. It now forms a significant fraction of the Himalayan collisional orogen.

Análisis del tratamiento en medio ácido de partículas de pizarra

Boletín de la Sociedad Española de Cerámica y Vidrio, 2002
Slate particles were treated in liquid acid medium. The results were analyzed as a function of the disolved ions and specific surface area values. Infrared spectroscopy (FT-IR) and X- ray difraction were also used in this study.

Removal Process of Structural Oxygen from Tetrahedrons in Muscovite during Acid Leaching of Vanadium-Bearing Shale

, 2018
Process mineralogy shows that most vanadium in mica-type black shale exists in the octahedral sites of muscovite. The extraction of vanadium mainly occurs in the acid leaching process with participation of H ions.

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas, Volume 55, Issue 2, Page 542-559, April 2026.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.
