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.

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]

, 2001
Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

Raman microspectroscopy of monazite-(Ce) and xenotime-(Y): examples from experiments and nature

Annales Societatis Geologorum Poloniae
This work presents an investigation of naturally and experimentally unaltered and altered monazite-(Ce) and xenotime-(Y), as well as secondary phases and synthetic REE phosphates ($YPO_{4}$ and $LaPO4–LuPO_4$) with Raman microspectroscopy, using 488 nm, 532 nm, 633 nm and 780 nm excitation lasers, supplemented by electron probe microanalysis (EPMA) and

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

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.

Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

Journal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Characteristics of Treated Monazite in Different Particle Sizes to Upgrade the Rare Earth Elements Content by Using Mechanochemical and Roasting Processes

International Journal of Technology
Rare earth metals (REE) constitute one of the most crucial groups of elements globally. In Indonesia, deposits of REE have been recognized within monazite minerals extracted from tin mining operations in Bangka.
