Geology and Geochemistry of the Early Proterozoic Kortejärvi and Laivajoki Carbonatites, Central Fennoscandian Shield, Finland [PDF]
This paper provides for the first time extensive petrological, mineralogical and geochemical data on the early Proterozoic Kortejärvi and Laivajoki carbonatites, northern Finland, which form metamorphosed and highly strained bodies 2 and 4 km long within

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.

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.

REE Zoning in Allanite Related to Changing Partition Coefficients During Crystallization: Implications for REE Behaviour in an Epidote-Bearing Tonalite [PDF]
Allanite is present in most samples of the tonalitic Bell Island Pluton, with an average mode near 0.05 wt.%. Allanite occurs as cores in igneous epidote-clinozoisite and exhibits characteristic and consistent zoning patterns.

CONCENTRIC-ZONAL AGGREGATE OF REE MINERALS IN FELDSPAR PEGMATITE OF THE VISHNEVYE MOUNTAINS, SOUTH URALS [PDF]
A concentric-zonal texture of mineral aggregate observed in alkali pegmatite of the Vishnevye Mountains was formed as a result of melt-fluid crystallization in a closed system.

RARE EARTH MINERALS IN ALKALINE AND SUBALKALINE ROCKS OF THE BALBUK COMPLEX (SOUTH URALS) [PDF]
Mineral composition of alkaline and subalkaline rocks of the Balbuk complex (South Urals) is characterized. The major REE minerals are monazite-(Ce), allanite-(Ce), and rhabdophane-(Ce).

Allanite Geochemical Response to Hydrothermal Alteration by Alkaline, Low-Temperature Fluids
Allanite is one of the main rare earth elements (REE)-rich accessory minerals in composite dykes from the granitoid pluton of Karkonosze. These dykes differ in composition from the bulk of the pluton by elevated rare earth elements (REE), Y, Zr, and ...
