Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Most detrital zircon studies generate grayscale cathodoluminescence (CL) images, U/Pb dates, and variably extensive trace element concentration data. Yet the combined information contained in these data is rarely used for a higher‐level interpretation of zircon provenance, which still heavily relies on comparison of sample‐wide U/Pb age ...

Occurrence of Rare Earth Elements in Deep-Sea Mud from the Western Pacific Ocean
Kuangchan zonghe liyong, 2022 Deep sea mud is a new type of rare earth elements resources with potential economical significance. However, the occurrence of Rare Earth Elements is contradictory. Through systematic study on mineralogy of the deep-sea mud from the Western Pacific Ocean,

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

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.
