Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

Terra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

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,

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,

Looking Under the Orogenic Lid—Assessing the European Basement Beneath the Alpine Wedge by U‐Pb Zircon Geochronology

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Following continental collision, the distal European margin was overridden by the Alpine wedge and is now largely concealed beneath the mostly intact orogenic lid. Consequently, the geological evolution and nature of the hidden basement domains remain poorly constrained.

First data on Th–REE mineralization in mafic-ultramafic igneous rocks of the western slope of the Southern Urals

Georesursy
The article presents the first data on rare earth mineralization in differentiated intrusions on the western slope of the Southern Urals. When studying the mineralogy of the rocks of the Shuida, Misaelga, Ishliy and Lysogorsk complexes, minerals of rare ...
