An in-situ electron microscopy study of dual ion-beam irradiated xenotime-type ErPO$_4$

open access: yes, 2020
International audienceRare-earth phosphates adopting the xenotime (REPO 4 ; RE = Tb − Lu & Y, Sc) structure are proposed as a potential matrix for the confinement of minor actinides.

Global Copper Deposit Dataset: A New Open‐Source Database for Advanced Data Analysis and Exploration Targeting

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...

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.

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

Data for: Two kinds of authigenic xenotime overgrowths in response to an Early Paleozoic tectonothermal event in South China

open access: yes, 2019
This study has documented two kinds of xenotime overgrowths from the Cryogenian-Ediacaran sedimentary rocks in South China. The identical tetragonal dipyramidal structures prompted one type of xenotime to overgrow detrital zircon grains, whereas the ...

An Evaluation of Dating of Diagenetic Xenotime by Electron Microprobe.

open access: yesMicroscopy and Microanalysis, 2000
Abstract Xenotime is an igneous mineral commonly present in pegmatite and fractionated granite. Recent studies reveal that it also forms as a diagenetic mineral. Minute (0.1-5 μm) xenotime overgrowths typically crystallise on the surfaces of detrital zircon shortly after sedimentation, in a wide range of siliciclastic sedimentary units ...

REE-bearing minerals in the Rapakavi Grante, Southern Finland

open access: yesOpen Geosciences, 2015
The studied rock samples belong to the classic1615–1645 Ma Wiborg Rapakivi granite terrane of southeasternFinland. Geochemical studies show that the rapakivigranites and associated rocks form metaluminousto peraluminous A-type granites and plot in the ...
