![]() In the two samples collected close to the major Wenchuan Shear Zone-deformed up to mylonitization and retrogressed under greenschist-facies conditions (3–4 ± 1 kbar, 350–400☌)-allanite still preserves the peak metamorphic ages ( c. The timing of allanite appearance strongly correlates with the biotite-in reaction predicted by the models and observed in microstructures. 200 Ma, whereas syn- to post-garnet allanite has ages of c. This relative chronology is confirmed by in situ U–Th/Pb allanite dating: pre-garnet allanite shows ages of c. In the two samples where allanite is observed as inclusions in garnet, garnet shows no textural zoning and a low Y content ( 520☌). Garnet is, along with allanite, critical to reconstruct the REE budget of these rocks. Allanite is the main rare earth element (REE)-bearing accessory mineral but it exhibits different textures, such as epidote rims with distinct REE contents as well as late inclusion-like dissolution features. All samples experienced similar peak temperatures of 560–600☌. Microstructural observations were combined with whole-rock compositions, detailed mineral characterization, phase equilibria modelling, and in situ U–Th/Pb allanite dating to gain insights into the allanite reactivity relative to other rock-forming minerals. This study focuses on five garnet–biotite metapelites retrogressed to different extents, from the internal domain of the Longmen Shan (eastern Tibet) from which few petrochronological data documenting the metamorphic ages are available. Memorial contributions may be made to the Shriners Hospitals for Children.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. until the time of services Monday in the church.
