Evaluation of Iron‐Phosphate Glass–Ceramic Waste Form for Electrorefiner Salt Waste Simulant Dechlorinated With Phosphoric Acid

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This work investigates the formation of high‐alkali‐iron‐phosphate glass–ceramic waste forms made from the dechlorinated product of a phosphoric acid‐based process. The salt simulant is mixed with H3PO4 to form a slurry, heated, and then the dechlorinated product is vitrified with glass formers to obtain the final waste form. ABSTRACT The importance of

Monazite and Xenotime U‐Pb Geochronology and Thermometry of the Blue Ridge and Inner Piedmont of North Carolina: Implications for the Thermal‐Metamorphic Evolution of the Southern Appalachian Metamorphic “Core”

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The southern Appalachian orogen preserves a complex distribution of metamorphism and deformation varying in timing, magnitude, and spatial extent. These complexities give rise to disparate interpretations for southern Appalachian tectonic evolution, which complicates the testing and interpretation of tectonic models in this system.

Which oxidation state of uranium and thorium as point defects in xenotime is favorable? [PDF]

, 2021
Relativistic study of xenotime, YPO$_4$, containing atoms thorium and uranium as point defects is performed in the framework of cluster model with using the compound-tunable embedding potential (CTEP) method proposed by us recently. The Y-(PO$_4$)$_6$-Y'$

Two metamorphic cycles recorded by monazite in eclogite-facies gneisses (Southern Armorican Massif, France): A Cambro-Ordovician continental crust involved in eo-Variscan subduction

BSGF - Earth Sciences Bulletin
We present U-Th/Pb data obtained for xenotime and monazite from the polycyclic eclogite-facies para- and ortho-gneisses of the Les Essarts Unit (Vendée, southern Armorican Massif, France), which have recorded an HT-LP cycle ending with a first ...

Provenance and Petrological Evolution of Sand Injection Complexes: Insights From Heavy Mineral Analysis in the Paleogene Forearc Succession of the San Joaquin Basin

Basin Research, Volume 38, Issue 3, May–June 2026.
The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

Investigation of Thermoluminescence Characteristics and Kinetics of Natural Obsidian

Luminescence, Volume 41, Issue 4, April 2026.
Thermoluminescence (TL) properties of natural obsidian from the Aksaray region were investigated under beta irradiation. The study identifies optimal grain size, evaluates kinetic parameters via Tm–Tstop and computerized glow curve deconvolution (CGCD) methods, and demonstrates the material's potential for low‐dose environmental and personal radiation ...
