Abstract EN
-Representative plutonic rock samples from Afif (19 samples) and Al-Hijaz (16 samples) were analyzed for their content of REE.
The parameters of these REE were calculated and compared for the two terranes and ehondrite-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 lerrane.
The gahbro-dioritic rocks in Afif terrane show more fractionation and enrichment.
REE patterns for gabbro-dioritic rocks arc different in the two terranes.
This suggests different evolutionary mechanisms as well as differences in the composition of their parental magmas.
