Low Temperature Leaching Behavior of Allanite-(Ce) in Treating an Allanite-Concentrate by Sulfuric Acid [PDF]
Allanite is a common REE-bearing silicate mineral, which is found in potentially mineable abundances in many areas but has not been economically exploited for the REEs in an industrial scale.

Site splitting at M3 in allanite-(Ce)
We report the crystal structure of allanite-(Ce), with composition (Ca1.0REE0.90.1)(sigma 2.0)(Al1.46Fe0.523+Fe0.762+Mg0.12Ti0.15)(sigma 3.01)Si3O12(OH) from the Xinfeng rare earth element (REE)-bearing granite in Guangdong Province, China.

Strain partitioning in host rock controls LREE release from allanite-(Ce) in subduction zones [PDF]
Combined microstructural, mineral chemical, X-ray maps, and X-ray single-crystal diffraction analyses are used to reveal the rheological behaviour of individual grains of magmatic allanite relicts hosted in variably deformed metagranitoids at Lago della ...

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

Allanite Petrochronology in Fresh and Retrogressed Garnet–Biotite Metapelites from the Longmen Shan (Eastern Tibet) [PDF]
Linking the timing of allanite growth to metamorphic conditions in metapelites is particularly challenging because of the large variety of allanite textures and chemical compositions.
