Monazite, xenotime, and allanite are REE 1-minerals sensu stricto because lanthanides
(La… Lu) and yttrium are critical constituents in them. Apatite does not require REE, but …

In this chapter, an overview of the findings to date from laboratory measurements of diffusion
of cations in the accessory mineral phases zircon, monazite, apatite, titanite (sphene) and …

Low-temperature alteration of monazite is documented in three centimeter-sized monazite
crystals from Norway (Arendal), Madagascar (Ambato), and Sri Lanka. The three crystals …

Monazite is a light rare earth element (LREE)-rich phosphate mineral that occurs as a trace
phase in a wide variety of rock types, where it forms in response to different geological …

The synthesis methods, crystal structures, and properties of anhydrous monazite and
xenotime (REPO4) crystalline materials are summarized within this review. For both …

Alteration experiments on natural monazite crystals (Manangotry standard, Madagascar)
under alkali conditions at 300, 400, 500 and 600° C and 200 MPa were conducted to clarify …

Monazite [(LREE) PO4], a common accessory mineral in magmatic and metamorphic rocks,
is complementary to zircon in U–Th–Pb geochronology. Because the mineral can record …

U–Pb geochronology of shocked monazite can be used to date hypervelocity impact events.
Impact-induced recrystallisation and formation of mechanical twins in monazite have been …

A significant effort has been made by the scientific community to evaluate the potential of
phosphate minerals and glasses as nuclear waste storage hosts. Radioactive waste-bearing …

The conditioning of radioactive waste from nuclear power plants and in some countries even
of weapons plutonium is an important issue for science and society. Therefore the research …
