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

Chemie 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.

Mantle flow influence on subduction evolution [PDF]

, 2018
The impact of remotely forced mantle flow on regional subduction evolution is largely unexplored. Here we investigate this by means of 3D thermo-mechanical numerical modeling using a regional modeling domain. We start with simplified models consisting of

Flow cytometry‐based monitoring of chimeric antigen receptor (CAR) T cells: Reagent selection, assay design, and clinical utility

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Accurate quantification of chimeric antigen receptor (CAR) T cells is essential for monitoring post‐infusion CART expansion and persistence and for real‐time clinical decision‐making. Multiparameter flow cytometry (MFC) enables rapid, live‐cell detection with absolute quantification and concurrent immunophenotypic characterization. This review

Cu‐Isotope Evidence for Subduction Modification of Lithospheric Mantle

Geochemistry, Geophysics, Geosystems, 2022
Ultramafic xenoliths from southeastern Arizona, USA, provide evidence for Cu‐isotope heterogeneity in the lithospheric mantle. We report new data on Type I (Cr‐, Mg‐rich) peridotites, but also the first Cu‐isotope data for Fe‐Ti‐Al‐rich Type II ...

Carbon-driven Chemical Interactions between Alumina and Iron: A possible reaction pathway in Earth's interior [PDF]

, 2008
Seismological and geochemical observations have revealed a complex structure for the earth's core-mantle boundary (CMB) region, with lateral and chemical heterogeneities.

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

Deep 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.

Effects of Heat‐Producing Elements on the Stability of Deep Mantle Thermochemical Piles

Geochemistry, Geophysics, Geosystems, 2020
Geochemical observations of ocean island and mid‐ocean ridge basalts suggest that abundances of heat‐producing elements (HPEs: U, Th, and K) vary within the mantle.

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

Seamounts in the Subduction Factory [PDF]

Oceanography, 2010
The “Subduction Factory” is a metaphor for the geochemical processing of subducted oceanic crust and sediment into components that are either incorporated into the volcanic arc or recycled into Earth’s mantle.

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

Geological 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.
