Xenotime is a rare-earth phosphate mineral, the major component of which is yttrium orthophosphate. The phosphate ions are described by a tetrahedral shape and coordinate to the center Y3+ metal ion i
Libethenite
…is found in the oxidized zone of copper ore deposits. It is most often formed from the weathering of phosphate rocks such as apatite, monazite, and xenotime. There have been no confirmed findings of primary libethenite, although a probable case has been reported…
