The Noorabad ophiolite is a part of Eastern Mediterranean-Zagros-Oman Tethyan ophiolites, cropping out in south-southwest of the Main Zagros Thrust fault. In this sequence of the ophiolite rocks, diabase dikes and basaltic lavas are widespread. The chemical composition of these rocks comprise sub-alkaline basalts, andesitic basalt and andesite. According to normalized REE diagrams to the chondrite and trace elements normalized to the primitive mantle, these rocks show calc-alkaline series, the enrichment of LREE and LILE and depletion of HFSE elements. The characteristics of these ophiolites are similar to other exposed Tethyan ophiolites along Bitlis-Zagros suture zone, and their formation is associated with supra-subduction zones.
