Variscan metamorphism in the eastern Pyrenees and its relation to Late-Variscan magmatism revealed by U-Pb zircon dating: implications for the configuration of the Variscan Belt in the NE Iberian Peninsula [PDF]
, 2014 Variscan migmatites cropping out in the eastern Pyrenees were dated together with Late Variscan plutonic rocks. Upper Proterozoic–Lower Cambrian series were migmatized during a thermal episode that occurred in the interval 320–315 Ma coeval with the main

Mineralogical MagazineAbstractATO4 compounds are a class of oxides which includes the rare earth element (REE) bearing phosphates and arsenates, REEPO4 and REEAsO4. In this study, we have investigated the isothermal high-pressure and the isobaric high-temperature behaviour of natural samples of xenotime-(Y) (ideally YPO4), chernovite-(Y) (YAsO4) and monazite-(Ce) (CePO4 ...

Synthesis of monazite (RPO4, R=La, Ce, Nd, or Sm) by solid state reaction.
Mineralogical Journal, 1991 Syntheses of monazite (RPO4, R=La, Ce, Nd, or Sm) were carried out by heating the mixture of [RCl3, R2O3, Ce(NO3)3, or CeO2] and [(NH4)2HPO4, K2HPO4, Na2HPO4, or H3PO4)] with the atomic ratio (P/R) of 1 at 200–1000°C for 1 day. Products observed were monazite-(La, Ce, Nd, or Sm), hexagonal RPO4·nH2O, Ce(PO3)3, Ce(PO3)4, and CeP2O7. Single monazite-(La,
