Ecological Research, Volume 41, Issue 1, January 2026.The Peak Range Volcanics in central Queensland, Australia is naturally enriched with REEs (Rare Earth Elements). Fieldwork was conducted to analyse REEs in plant species occurring in this area. ABSTRACT Rare Earth Elements (REEs) are critical for high‐tech technologies in the green energy transition.

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Even if the concentration of photoactive centers is high, concentration quenching may be avoided when the concentration of quenching centers is sufficiently low, and excitation migration through photoactive centers and subsequent deactivation at quenching centers is the main quenching mechanism.

Electron microprobe technique for U-Th-Pb and REE chemistry of monazite, and its implications for pre-, peak- and post- metamorphic events of the Lutzow-Holm Complex and the Napier Complex, East Antarctica [PDF]
, 2006 Monazites in high-grade metapelites from the Lutzow-Holm Complex and Napier Complex have been examined in terms of U, Th, Pb and rare earth element (REE) chemistry using an electron microprobe.

Resource Geology, Volume 76, Issue 1, January/December 2026.Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

Acta Crystallographica Section E Structure Reports Online, 2005 Yb[AsO4], ytterbium(III) oxoarsenate(V), adopts the xenotime structure type. Single crystals were obtained in an attempt to synthesize a compound with nominal composition Yb3OCl[AsO3]2 by fusing a mixture of Yb2O3, YbCl3 and As2O3 in a 4:1:3 molar ratio at 1123 K, owing to air-intrusion during the reaction.

Tectonics, Volume 44, Issue 12, December 2025.Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...
