Rare Earth Elements in Plants of the Peak Range Volcanics (Queensland), Australia Exploration Target: A Biogeochemical Prospecting Tool

open access: yesEcological 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.

Xenotime dissolution dynamics under neutral and acidic conditions [PDF]

open access: yes, 2013
Dissolution dynamics of synthesized xenotime was experimentally studied in a discontinuous flow–through reactor. The dissolution rate constants derived from yttrium release were determined as (1.71 ± 0.74) × 10-17 mol/m2/s in near neutral solution (pH ...

Field Mapping and Zircon U–Pb Dating of the Early Paleozoic Amphibolite‐Facies Paragneiss in the South Kitakami Belt, NE Japan: Implications for the Sedimentary and Metamorphic History of Proto‐Japan

open access: yesIsland Arc, Volume 35, Issue 1, January/December 2026.
ABSTRACT The early Paleozoic tectonic setting of proto‐Japan remains poorly constrained. In the South Kitakami Belt in Northeast Japan, Ordovician–early Silurian basement rocks and overlying Silurian–Cretaceous shallow marine sediments are widely distributed.

Optimization of the process of obtaining RE 2 O 3 from xenotime using statistical design

open access: yesCerâmica
The study of the production of the mixed rare earth oxide (RE2O3) from xenotime via hydrometallurgy was performed to evaluate the significance of the effects of three factors including the melting temperature (A), the ratio of NaOH/xenotime (B), and time

Negligible concentration quenching in transparent silica–rare‐earth orthophosphate glass‐ceramic phosphors

open access: yesJournal 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.

Synthesis and properties of anhydrous rare-earth phosphates, monazite, and xenotime: a review [PDF]

open access: yes
This article summarizes the synthesis methods, crystal structures, and properties of anhydrous monazite and xenotime (REPO4) crystalline materials. For both monazite and xenotime, currently available Inorganic Crystal Structure Database data were used to

Fluorapatite-hingganite-(Y) coronas as products of fluid-induced xenotime-(Y) breakdown in the Skoddefjellet pegmatite, Svalbard [PDF]

open access: yes, 2011
The pre-Caledonian NYF Skoddefjellet pegmatite in Wedel Jarlsberg Land, Svalbard, contains xenotime-(Y) that is partly replaced by fluorapatite-hingganite-(Y) reaction coronas.

Geochemistry and U–Pb Zircon Geochronology of Granite at the Pilok Sn–W Deposit, Thailand: Implications for Late Triassic Tin Metallogenesis

open access: yesResource 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

Exsolution of thortveitite, yttrialite, and xenotime during low-temperature recrystallization of zircon from New Caledonia, and their significance for trace element incorporation in zircon [PDF]

open access: yes, 2004
Recrystallized zircon grains in a phengite-epidote-chlorite schist from north-eastern New Caledonia contain as inclusions a mineral assemblage consisting of celadonite, kaolinite, quartz, Fe-oxy-hydroxide,smectite, chlorite, xenotime-(Y), thortveitite ...
