Data for: Two kinds of authigenic xenotime overgrowths in response to an Early Paleozoic tectonothermal event in South China [PDF]
, 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 ...

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization
Journal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
Terra Nova, Volume 38, Issue 1, Page 65-76, February 2026.ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Geoscience 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 ...

Distinguishing xenotime and zircon in ores and estimating the xenotime content for on-site analysis
Spectrochimica Acta Part A: Molecular and Biomolecular SpectroscopyEstimation of the content of the major minerals containing rare earth element (REE) (e.g., xenotime, monazite, and bastnäsite) to extract metal REEs is a critical task for efficient exploration of mines with REE reserves. X-ray-excited optical luminescence (XEOL) imaging is a promising method for estimating the REE-bearing mineral content on-site ...

Decomposition of Xenotime with Sulfuric Acid
The Journal of the Society of Chemical Industry, Japan, 1962 マライ産ゼノタイムを試料として用い,硫酸によって分解するときの最適条件を求めることを目的とし,微粉砕試料について硫酸量,硫酸濃,処理温度,処理時間などと希土類元素の抽出率との関係について検討した。小規模な実験において,微粉砕試料ではつきのような条件でほとんど完全に分解する。(1)試料:硫酸1:2.0,(2)硫酸濃度95%,(3)処理温度250℃,(4)処理時間30分。ゼノタイム試料についてはX線分析によっても検討した。
