摘　　要：The Mianrahan’s ophiolitic complex out crops in the northeast of Kermanshah and along with the Zagros thrust zone. In Mianrahan sheet, these ophiolites are located along the NW-SE and parallel to the Zagros Thrust in the ground. The rocks of this ophiolite complex consist of peridotite, serpentinites, gabbro, dolerite dykes, basaltic lavas associated with marine sediments containing the cretaceous limestones, siliceous limestones and radiolarites. Stratification of this ophiolitic complex is similar to lithological facies sequence of the oceanic crust. However, in some parts, it could be seen as scattered and melanged in the ground. Petrographic study of Mianrahan’s ophiolitic complex started with the ultramafic sequence and followed by sedimentary rocks.The Mianrahan’s ophiolitic complex out crops in the northeast of Kermanshah and along with the Zagros thrust zone.
