Rare-earth mineralization in ores of the Gurvunur apatite-magnetite deposit (Ozerny ore cluster, Western Transbaikalia)

Руды и металлы
The Gurvunur apatite-magnetite deposit is located within the Ozerny ore cluster in Western Transbaikalia. A peculiarity of this object is the presence of rare-earth mineralization in the ores. The main REE concentrator minerals include monazite, allanite,

REE AND SR MINERALIZATION WITH PERRIERITE-(CE) IN ALKALINE SILICATE-CARBONATE ASSEMBLAGE OF THE CONTACT ZONE OF THE VISHNEVOGORSK BLOCK (SOUTH URALS) [PDF]

Минералогия, 2016
The REE and Sr minerals (perrierite-(Ce), allanite-(Ce), ankilite-(Ce), monazite-(Ce), «cerphosforhuttonite») were identified in the apatite-albite-phlogopite-calcite veins of the contact zone of the Vishnevogorsk miaskite block.

Tracing Orogenic Evolution From Multi‐Detrital Mineral Records: U‐Pb Geochronology and Trace‐Element Constraints From Glacial Diamictites

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Monazite-(Ce) formation as a product of hydrothermal chevkinite-(Ce) alteration: Experimental constraints

Mineralogia
Chevkinite-group minerals are rare earth element (REE) carriers in alkaline magmatic and metasomatic systems, yet their hydrothermal stability and alteration pathways remain poorly constrained.

NEW FINDINGS OF RARE MINERALS IN PEGMATITES OF VISHNEVYE MOUNTAINS IN THE SOUTHERN URALS [PDF]

Минералогия, 2019
In addition to previously known 221 minerals, 11 new rare minerals were identified in alkali pegmatites of the Vishnevye Mountains. Yttrialite-(Y)Y2(Si2O7) and huanghoite-(Ce) aCe(CO3 2F were found for the first time in the Urals.

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

A Raman spectroscopic study on the structural disorder of monazite Ce

, 2012
This study addresses whether Raman spectra can be used to estimate the degree of accumulated radiation damage in monazite Ce samples whose chemical composition was previously determined. Our results indicate that the degree of disorder in monazite Ce ,

Monazite-(Ce) and xenotime-(Y) from an LCT, NYF tertiary pegmatite field: Evidence from a regional study in the central alps (Italy and Switzerland) [PDF]

, 2016
Monazite-(Ce) and xenotime-(Y) from tertiary pegmatites of the central Alps (Italy and Switzerland) were studied by EMPA and SCXRD analytical methods. The REE-phosphate minerals analyzed are from LCT and NYF pegmatite dikes of the Central Alps, which ...

Role of Post‐Collisional Magmatism in Continental Growth and Reworking Since the Late Archean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The mechanisms responsible for the formation and compositional evolution of continental crust remain central questions in Earth science. Post‐collisional magmatism is widely preserved in the continental record; however, its contribution to crustal growth may be underestimated because enriched isotopic signatures obscure juvenile mantle input ...

Extraction of Ce and Th from Monazite Using REE Tolerant Aspergillus niger

, 2017
In the present study, bioleaching of monazite, one of oldest and most water-resistant mineral to microbial attack, was tested for its amenability toward extraction of Ce, Th, and U using heterotrophic fungal species, Aspergillus niger.
