Glass stability (GS) of chemically complex (natural) sub-alkaline glasses [PDF]

open access: yesarXiv, 2018
Glass stability (GS) indicates the glass reluctance or ability to crystallise upon heating; it can be characterised by several methods and parameters and is frequently used to retrieve glass-forming ability (GFA) of corresponding liquids as the case with which such liquids can be made crystal free via melt-quenching.

Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls

open access: yesJournal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022
Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

Komatiites: From Earth's Geological Settings to Planetary and Astrobiological Contexts [PDF]

open access: yesarXiv, 2005
Komatiites are fascinating volcanic rocks. They are among the most ancient lavas of the Earth following the 3.8 Ga pillow basalts at Isua and they represent some of the oldest ultramafic magmatic rocks preserved in the Earth's crust at 3.5 Ga. This fact, linked to their particular features (high magnesium content, high melting temperatures, low dynamic

Diverse Deformation Mechanisms and Lithologic Controls in an Active Orogenic Wedge: Structural Geology and Thermochronometry of the Eastern Greater Caucasus

open access: yesTectonics, Volume 41, Issue 12, December 2022., 2022
Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Permeability of volcanic rocks to gas and water

open access: yesJournal of Volcanology and Geothermal Research, 2018
Abstract The phase (gas or liquid) of the fluids within a porous volcanic system varies in both time and space. Laboratory experiments have shown that gas and water permeabilities can differ for the same rock sample, but experiments are biased towards rocks that contain minerals that are expected react with the pore fluid (such as the reaction ...

Metal Nitride Catalysts for Photoelectrochemical and Electrochemical Catalysis

open access: yesExploration, EarlyView.
Metal nitrides exhibit excellent electrical conductivity and catalytic activity, making them promising for (photo)electrochemical reactions. This review explores their electronic structure, surface chemistry, and synthesis strategies, emphasizing morphology and phase control.

Fine description and geologic modeling for volcanic gas reservoirs

open access: yesPetroleum Exploration and Development, 2010
To understand the geology of volcanic gas reservoir development, research was carried out on volcanic rock, body lithology, lithofacies, fractures, gas and water zones, reservoir classification, and geologic modeling for volcanic gas reservoirs.

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...
