Xenotime is a rare phosphate mineral primarily composed of yttrium and phosphate. It typically appears as yellowish-brown to greenish crystals and is often found in granitic and pegmatitic rocks. Xenotime is significant for its use as a source of rare earth elements, particularly yttrium, which is important in various high-tech applications. This mineral is commonly associated with other minerals such as zircon and monazite. Due to its rarity and unique properties, xenotime is of interest to mineral collectors and researchers studying geology and mineralogy. Its formation occurs under specific geological conditions, making it a valuable indicator of certain geological processes.
