| Zusammenfassung |
| Monazite (CePO4) and xenotime (YPO4) are widespread accessory minerals in
metapelites and metgranitic rocks and are considered to be important carriers concerning
geochronological and petrological information about a metamorphic overprint. Although the
distribution of rare earth elements (REE) during high-grade metamorphism has
long been a subject of intense research (e.g. Pan and Fleet, 1996), experimental
investigations on monazite solubility at high P-T are scarce (Ayers and Watson, 1991;
Ayers et al., 2001). Therefore, understanding the solubility behaviour of CePO4
and YPO4 under high-grade P-T conditions is essential for the interpretation of
REE distribution patterns in high-grade rocks. In order to set constraints on the
solubility of CePO4 and YPO4 under high-grade P-T conditions, we carried out a series
of weight-loss experiments of single crystals of synthetic CePO4 and YPO4 in a
piston-cylinder apparatus at 800 |
