Locations of Deposits

Xenotime preferentially incorporates heavy rare earth elements (HREEs) while monazite incorporates light rare earth elements (LREEs). This is important because LREEs are much more readily available and therefore a xenotime deposit may be more valuable than a deposit of monazite.
