Abstract

The studied area as a part of Urmiyeh-Dokhtar magmatic arc, situated in NE of 1:100000 geological map of Kahak and about 10 Km south of Fordu village.The genetic type of mineralization is intrusion related which a dioritic body influenced the country rocks and produced a pyrometasomatic zone of the following minerals such as: magnetite- hematite, andalusite-kyanite, hydrogrossular garnet, tremolite- actinolite, epidote, recrystallized carbonate and chloritized biotite. The fluxing agent of this dioritic intrusion varies from its marginal boundary to farther parts. Magnetite and hematite are the initial ore-minerals which accompanied by pyrite in places.The metasomatised country rocks are initially Eocene volcanoclastics and associated carbonates. These data have shown that the studied area is a calcic Fe-SKARN and also indicates a hornblende hornfels facies of 460 to 12 650o.The SKARN production by dioritic body acrossed the Qom formation specially limestones in outer parts of the studied area also occurred, therefore the age of the dioritic intrusion seems to be post Eocene probably middle Miocene.The initial factors controlling the metasomatism mechanism are the dioritic emplacement, its related fluxing agents and the lithology of the country rocks.The tectonomagmatic site of the above dioritic body and associated metasomatism indicate a subduction zone of continental magmatic arc (VAG) based on the related described diagrams.
