petrographic and minerologic studies of hornfelses from north of fesharak ucllage (northeast esfahan)

the area under study is located 75 km north of isfahan north of fenshark village.the mesozoic deposits of this area have been metamorphosed in the vicinity of neogene granodiorites and quartzdiorites ,forming hornfelses in three individual facies albit-epidot-hornfelses in three individual facies albit-epidot-hornblende-and pyroxene hornfels. wollastonite,vesuvianite,garnet and calcite are the mjor mineral of the rocks.the wollastonite which is 2m-typ and occurs in hornblende-and pyroxene hornfels.vesuvianite having ferri from have been mainly crystallized in pyroxene facies few are present in hornblende facies too.granots having a composition of grossular and andradite,are associated with calcitquartz in all facies.
