Experimental alteration of allanite at 200 °C: the role of pH and aqueous ligands
Geological Society Special Publication, 2023 Allanite is a major host of rare earth elements (REE) in the continental crust. In this study, reaction mechanisms behind allanite alteration are investigated through batch experiment runs on natural allanite grains in carbonate-bearing hydrothermal ...

Allanite in Variscan Post-Collisional Lamprophyre Dykes from Les Guilleries (NE Iberia) as a Part of Rare Earth Element Recycling in Collisional Orogens [PDF]
Minerals, 2022 Recent studies of Late Permian calc-alkaline lamprophyre dykes located in the Les Guilleries Paleozoic massif of the Catalan Coastal Range have revealed that allanite is present as the main REE-bearing accessory phase, which is the object of this study ...

Allanite Petrochronology in Fresh and Retrogressed Garnet–Biotite Metapelites from the Longmen Shan (Eastern Tibet) [PDF]
Journal of Petrology, 2018 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.

Pre-Alpine thermal history recorded in the continental crust from Alpine Corsica (France): evidence from zircon and allanite LA-ICP-MS dating [PDF]
Swiss Journal of Geosciences, 2020 The pre-Alpine history of the Venaco-Ghisoni Unit, a continental unit belonging to the Alpine Corsica (France), was reconstructed on the basis of U–Pb dating of zircon and allanite.

Non-matrix-matched standardisation in LA-ICP-MS analysis: general approach, and application to allanite Th–U–Pb dating [PDF]
, 2017 To make use of the full geochronological potential of accessory minerals such as zircon, allanite, monazite, and titanite, high spatial resolution isotopic analysis of the Th–U–Pb system is required.

Allanite Geochemical Response to Hydrothermal Alteration by Alkaline, Low-Temperature Fluids
Minerals, 2020 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 ...
