The study area is located within the shear zone of north Shahrekord. There are many small and medium granitoid plutons that have intruded in the metamorphic rocks with Middle Jurassic in age. These rocks show sharp mylonitic foliation and lineation as the results of undergoing strong deformation.  Most of these granitoid plutons contain the assemblage of quartz + K-feldspar + plagioclase + biotite + hornblende + allanite + titanite + magnetite + magmatic epidote + apatite + zircon ± garent in apparent textural equilibrium. Epidotes exhibit textural and compositional characteristics implying their magmatic origin. The granitoid plutons bearing magmatic epidote must have formed under moderately high pressures, corresponding to lower crustal depths. The Al – in – hornblende geobarometry yields pressures of 7.3 - 8.1 kbar (average 7.7 kbar) corresponding to a depth of about 28 Km. Also, amphibole–plagioclase geothermometry gives temperatures from 663 to 711 °C. The geothermobarometry results are in agreement with the presence of magmatic epidote in the granitods.
