Abstract : Representative plutonic rock samples from Afif (19 samples) and AI-Hijaz (16 samples) were analyzed for their content of REE. The parameters of these REE were calculated and compared for the two terranes and chondrite-normalized values plotted on various spider diagrams. LREE have a higher variation range than HREE. The sum of REE content is higher in Afif terrane-than in Hijaz terrane. The gabbro-dioritic rocks in Afif terrane show more fractionation and enrichment. REE patterns for gabbro-dioritic rocks are different in the two terranes. This suggests different evolutionary mechanisms as well as differences in the composition of their parental magmas
