Abstract
The Sol Hamed (SH) area is a part of the Arabian-Nubian Shield (ANS) ophiolites occurred within Onib-Sol Hamed suture zone in the southern Eastern Desert of Egypt. The ophiolitic assemblages in this area are represented by serpentinite, metagabbro and arc assemblages represented by metavolcanics. They later intruded by gabbroes and granites. The compatible trace elements (Cr = 2426-2709 ppm, Ni = 1657-2377 ppm and Co = 117-167 ppm) enrichment in SH serpentinites indicate derivation from a depleted mantle peridotite source. They show affinity to the typical metamorphic peridotites. The normative compositions reflect harzburgitic mantle source. Their Al(2)O(3) contents (0.05-1.02 wt %) are akin to oceanic and active margin peridotites and Pan-African serpentinites. The Cr and TiO(2) contents indicate supra-subduction zone (SSZ) environment. Their Al(2)O(3)/SiO(2) and MgO/SiO(2) ratios support the SSZ affinity and are similar to ANS peridotites with fore-arc setting. Moreover, their Al(2)O(3) and CaO depletion is typical of fore-arc peridotites.
