Introduction. Xenotime (YPO 4) is a trace mineral in many rock types (Rasmussen, 2005).Its significance far outweighs its low abundance and small grain size for two main reasons: 1) it forms in many common rock types from a range of high- to low-temperature processes, and 2) it is an excellent mineral for U/Pb geochronology, particularly in-situ geochronology where …
