Surface structure of natural muscovite

, 2010
The aim of this project is to study the atomic surface structure of a natural muscovite crystal thanks to the synchrotron radiation light and the grazing incidence X-ray diffraction (GIXRD).The muscovite studied [(K0.92Na0.08) (Al1.86Fe3+0.01Mg.0.07 Fe2 ...

Shies Protest: Blocking Moscow's Waste to Defend Northern Russia's Environment

Area, Volume 58, Issue 3, September 2026.
Short Abstract The Shies protest in Russia demonstrates how grassroots mobilisation can reshape extractivist projects by halting the construction of a massive landfill planned for Moscow's waste. From 2018 to 2020, local residents and environmental activists used blockades, protest camps and legal action to oppose ecological damage and governance ...

Assessment and Correction of Non‐Linearity Effects for In Situ Rb‐Sr Geochronology Applied to High 87Rb/86Sr Mica

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 601-624, September 2026.
Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.

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.

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 585-610, September 2026.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

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%).

Metamorphic Reactivity Influences Amphibole Creep Behaviour

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 611-632, September 2026.
ABSTRACT The rheological behaviour of solid‐solution minerals may play an important role in determining how metamorphic crust accommodates deformation. Whether or not a mineral's deformation is diffusion or dislocation‐mediated depends on a range of extrinsic variables such as stress, strain rate and temperature, as well as intrinsic variables such as ...

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2233-2257, September 2026.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...
