Abstract :

The Venarj plutonic body is part of Urumieh- Dokhtar Belt and crops out about twelve squars kilometres. This body Is composed of the following lithotypes:
Quartzdiorites, Granodiorites In part porphyritic, Quartz Monzodiorites, Syenlt.s Quartz- bearing ana Monzonlte.
Monzodioritic dikes are present in some parts of the plutonic body. Rhyodacite enclaves are present in
the granodiorites. The body shows a number of textural types, like porphyritic, coarse to medium- grainec and clastic. Some of the rocks are oriented as a result of syn- intrusive flow. The Venarj plutonic body it calcalkaline in character with Na> k, and all the lithotypes are peraluminous.
Geochemical data indicate that continental collision had occurred.
The Venarj body suite may be interpreted as a I- granite suite, generated from cabcalkaline magmatite! subjected to heating by underplating.
This body is cutting the Eocene volcanic rocks and the Oligo- Miocene limestone of the Qon' Formation, thus it is post- Miocene in aQe.
