REE- and actinide-bearing minerals contain geochemical and geochronological information, which is important to discuss rock-formation process (cf. Harlov, 2016 review article, Journal of the Indian Institute of Science). In metamorphic petrology, many researchers have focused on the minerals such as zircon, garnet, apatite, monazite and xenotime. Many previous studies of those minerals have been reported (e.g. Hoskin and Schaltegger, 2003, Reviews in Mineralogy and Geochemistry; Meagher, 1982, Reviews in Mineralogy and Geochemistry; Spear and Pyle, 2002, Reviews in Mineralogy and Geochemistry). Here, current understanding of REE- and actinide-bearing minerals is reviewed. Based on the review, future work direction of mineralogical studies on geochronometers is discussed focusing on monazite.
