Monazite Microstructures and Their Interpretation in Petrochronology
Frontiers in Earth Science, 2021 The phosphate mineral monazite (LREE,Y,Th,Ca,Si)PO4 occurs as an accessory phase in peraluminous granites and Ca-poor meta-psammopelites. Due to negligible common Pb and very low Pb diffusion rates at high temperatures, monazite has received increasing ...

Zircon to monazite phase transition in CeVO
, 2011 X-ray diffraction and Raman-scattering measurements on cerium vanadate have been performed up to 12 and 16 GPa, respectively. Experiments reveal that at 5.3 GPa the onset of a pressure-induced irreversible phase transition from the zircon to the monazite

Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization [PDF]
Journal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Thorium zoning in monazite: A case study from the Ivrea–Verbano zone, NW Italy
Journal of Metamorphic Geology, 2022 Metamorphism and partial melting of the lower crust is commonly assumed to cause depletion in heat producing elements (HPEs; K, U, Th). In the deep crust, volumetrically subordinate metasedimentary layers, which are source to crustal granites (sensu lato)

Journal of Metamorphic Geology, 2022 Rare earth element (REE) signatures of high‐U/Pb and high‐Th/Pb accessory minerals are typically used to link their ages to specific petrological processes (‘petrochronology’)—most notably the growth or breakdown of garnet.

Frontiers in Earth Science, 2021 We have dated the South Delhi orogeny, Aravalli-Delhi Mobile Belt (ADMB), NW India, using the tectonic fabric, geochemistry, and zircon-monazite geochronology as the proxies. The South Delhi Terrane (SDT), a passive margin domain in the ADMB, consists of

Evaluating preservation bias in the continental growth record against the monazite archive
Geology, 2021 Most recent models of continental growth are based on large global compilations of detrital zircon ages, which preserve a distinctly episodic record of crust formation over billion-year timescales.
