Introduction
REE accessory minerals play the important role in metamorphic petrology. Their significance is related to their hosting of trace elements in metamorphic rocks and, therefore, providing important information about evolution that these rocks experienced. Phosphates (especially apatite, monazite and xenotime) are probably the most important group of metamorphic minerals, because they might be used in wide range of investigations, including geochronology and geothermobarometry (see e.g. Spear and Pyle 2002 and references therein). Moreover, reactions in which these minerals took part might provide significant information about history a rock experienced (e.g. Finger et al. 1998, ...
