-The Fawakhir ophiolitic sequence is composed mainly of serpentinites, metagabbros, boninitic metagabbros and metavolcanics. The serpentinites have geochemical features similar to those of depleted-mantle peridotites. Major and trace element characteristics show that the ophiolitic metagabbro and metavolcanic rocks are of tholeiitic to calc-alkaline affinity. REE abundances in the metagabbros and metavolcanics are characterised by flat to fractionated patterns. The Fawakhir ophiolitic sequence… CONTINUE READING
