The story of rare earth elements (REEs): Occurrences, global

REEs are often categorised into two sub-groups as light rare earth elements (LREEs) and heavy rare earth elements (HREEs). The elements from 57 La to 63 Eu are considered as LREEs, whereas the elements from 64 Gd to 71 Lu, including Y are categorised as HREEs. These two categories of REEs occur in same deposits altogether except Sc.
