Tahereh Parsa; Monireh Kheirkhah; Mir Ali asghar Mokhtari

Volume 31, Issue 3 , December 2021, , Pages 49-60

https://doi.org/10.22071/gsj.2021.229547.1788

Abstract
  Cenozoic acidic volcanic rocks at the south of Qezel Ozan River are located within the Western Alborz-Azarbaijan magmatic zone and northern part of the Iranian-Turkish Plateau. The Oligocene acidic lavas in north part of Zanjan show rhyolitic to dacitic composition.  Hyaloporphyritic to hyalomicrolithic ...  Read More

Petrology

Azad karimi; ali ahmadi; Monireh Kheirkhah; Abdolreza Partabian

Volume 30, Issue 118 , January 2021, , Pages 25-36

https://doi.org/10.22071/gsj.2020.222846.1770

Abstract
  The peridotites from Marivan-Kamyaran ophiolite suite (MKO), outer Zagros ophiolite belt, western Iran, are studied for the petrological and geochemical characteristics. Both mantle and crustal peridotites are present in the Marivan-Kamyaran ophiolitic sequence. Extensive compositional variations in ...  Read More

Volume 22, Issue 88 , December 2013, , Pages 205-218

https://doi.org/10.22071/gsj.2013.53694

Abstract
  Many centres within Iran are Plio-Quaternary in age and so formed 10s of millions of years after initial Arabia-Eurasian collision. Both composite volcanoes and lava fields present from Anatolia to eastern Iran. Basaltic rocks from Maku in the northwest Azerbaijanprovince of Iran are part of a widespread ...  Read More

https://doi.org/10.22071/gsj.2010.55668

Abstract
  At the farthest end of NW Iran, the Quaternary basalts crop out in Azerbaijan province, located in Alpine – Himalaya belt and highly pleatue of Iran-Turkish, eastern Anatolian. The Quaternary volcanic units of NW Azerbaijan cover a broad compositional range from basalts, basaltic andesite, trachy ...  Read More
