Investigation of U(VI) Adsorption in Quartz–Chlorite Mineral Mixtures

open access: yes, 2016
A batch and cryogenic laser-induced time-resolved luminescence spectroscopy investigation of U­(VI) adsorbed on quartz-chlorite mixtures with variable mass ratios have been performed under field-relevant uranium concentrations (5 × 10–7 M and 5 × 10–6 M)

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

open access: yesJournal 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 ...

Metamorphic Reactivity Influences Amphibole Creep Behaviour

open access: yesJournal 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 ...

Mica-chlorite intermixing and altered chlorite from the Nevado-Filabride micaschists, Southern Spain

open access: yes, 1991
12 páginas, 4 figuras, 2 tablasMinerals with biotite-like optical properties occur in the Nevado-Filabride micaschists. The grains are highly pleochroic, variable in colour from light yellow to deep red, and strongly recall the descriptions given for ...

Dipole in North African Dust Deposition at the Last Glacial Maximum Explained by Shifted Wind Direction Under Steepened Meridional Temperature Gradients

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Geological records strongly suggest that, globally, Earth's atmosphere was much dustier than present during the Last Glacial Maximum (LGM) but the explanation is debated, with greater aridity, stronger/gustier winds and less effective washout from a drier atmosphere all invoked. Yet dust deposition can be spatially complex.

Iron‐Catalyzed Photochemical Degradation of Organics on Mineral Dust Aerosol Particles

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Iron is almost ubiquitous in mineral dust aerosol particles and is known to catalyze the photochemical degradation of organics. For the first time we measured the loss of organics in aerosol particles containing various mineral dusts, using citric acid as an organic proxy.

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface

The Trimouns Talc-Chlorite Deposit

open access: yes
International audienceThe recent results on metasomatism and deformation at Trimouns show unambiguously that the formation of talc-chlorite mineralization is associated with the rifting phase at the beginning of the Alpine cycle (250 Ma current), and ...
