Mineralogical and geochemical studies of intrusive body of Ghohroud.

The Ghohroud granitoid body is located 116 km of north-west of Isfahan on the magmatic strip of Urumieh-Dokhtar belt. The body of granodiorite and tonalite with middle Miocene age intruded into the Jurassic shale and sandstones as well as the Cretaceous and Eocene limestone and marls in the north and the south of Ghohroud village caused the contact metamorphic of surrounding rocks lead to formation of skarns. On the basis of the petrographic and geochemical data the Ghohroud body is granodiorite and tonalite in nature and calc-alkaline and meta-aluminous composition which point to I-type granite forms in the tectonomagmatic environment related to continental arc.
