ABSTRACT: 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.
