The study area is located in northern part of metamorphic belt of
Sanandaj-Sirjan in east of Hamedan Batolith. This area is mainly composed
of regional metamorphic rocks, such as staurolith, andalusite, silimanite and
garnet bearing mica schists and slates, with nearly NW-SE trend. The age of
these rocks (tectonites) are Pre-jurassic and have experienced two stages of
deformation during ductile deformation. The first schistosity (S1) formed at
the first phase (D1). The second phase (D2) was formed by sided forces
where the most of structures have formed by this force. The fabric elements
of second schistosity (S2) and second lineation (L2) formed in this phase. The
subfabric elements of quartz, due to its physicochemical characteristic, was
producted at this phase. Quartz grains, first and second schistosity and axes
of microfolds all have orthorombic symmetry.
