Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Re-equilibration of detrital muscovite and the formation of interleaved phyllosilicate grains in low temperature metamorphism, Northern Apennines, Italy

open access: yes, 1991
Low temperature metamorphosed clastic rocks of the northern Apennines (Verrucano) contain detrital and metamorphic muscovite along with aggregates of interleaved phyllosilicate grains.

A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

open access: yesGeological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Petrogenesis and Tectonic Setting of Late Mesozoic Felsic Magmatic Rocks in the Wangmushan Mining District, Northern Fujian, South China

open access: yesGeological Journal, EarlyView.
The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Influence of Fracture Volumetric Intensity on Strength Anisotropy of Foliated Rock Masses: Insights From a Synthetic Rock Mass Modeling Approach

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents a synthetic rock mass (SRM) methodology to investigate the influence of fracture volumetric intensity (P32$P_{32}$) on the strength anisotropy of foliated rock masses containing non‐persistent fracture sets. The approach integrates UAV‐based discontinuity mapping, discrete fracture network (DFN) modeling, and lattice‐spring
