Abstract
⺠Similar to MORB ophiolites, the metabasalts of Wadi Ghadir are characterized by high TiO2 values. ⺠Enrichment in LREE, Th and U indicate that Wadi Ghadir metabasalts are similar to contaminated MORB. ⺠The variable LILE-enrichment is due to source & crustal contamination & post-magmatic alteration. ⺠The low εNd(t) values of some samples reflect their contamination by slightly older arc crust. ⺠The degree of contamination of the Eastern Desert ophiolites increases from south to north.
