Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were used to explain a viable geodynamic hypothesis on the development of the southeastern Zagros Orogenic Belt. Supra-subduction zone ophiolites have been of particular importance in the reconstruction of regional tectonic evolution andformed near a main subducting oceanic plate. The history of the southeastern Zagros Orogenic Belt is composed of development of two oceanic crusts, referred to as the Neo-Tethys 1 and Neo-Tethys 2. The process of reconstructing of the plate tectonic evolution of the southeastern Zagros Orogenic Belt was proposed on the basis of "Latest Cretaceous-Neogene collision" hypothesis. The supra-subduction zone ophiolites in the southeastern part of the Zagros Orogenic Belt can be classified into "pull related fore-arc Neyriz ophiolites" and "back-arc Naien-Baft ophiolites".
