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

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 ...

Xenotime from the Podwiśniówka mine pit, Holy Cross Mountains (South-Central Poland) [PDF]
This report presents the results of petrographical and mineralogical (optical microscopy, SEM/EDS) study of xenotime derived from the Upper (Middle?) Cambrian rocks (Wiśniówka Sandstone Fm.) of the abandoned Podwiśniówka mine pit.

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
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

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.
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 MINERALS OF PHYLLITES OF THE MAIN CENTRAL THRUST OF THE TAMOR WINDOW AREA, EASTERN NEPAL [PDF]
A sample of chlorite-muscovite fillite metamorphosed under greenschist facies of metamorphism below biotite isograde of the Lower Himalayan Sequence from the Main Central Thrust zone of the Tamor tectonic window area (Eastern Nepal) are studied.

REE-bearing minerals in the Rapakavi Grante, Southern Finland
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 ...
