Geology, geochemistry and petrogenesis of Taftan volcano: An approach to geodynamic of Makran-Chagai magmatic arc

Jalil Ghalamghash; Meysam Akbari; Reza Jamal

Volume 32, Issue 4 , December 2022, , Pages 83-102


  The Taftan volcano hosts an extensive volcanic activity during Late Miocene to Quaternary where took place over Makran-Chagai subduction zone. Taftan rocks are mainly basaltic andesite, andesite, trachyandesite, and dacite that occur as lavas and pyroclastic rocks. They are characterized by basic-intermediate ...  Read More

Petrography and geochemistry of pyroclastic rocks from the Badam area, E- Mahabad- West Azarbaijan Province

Ashraf Torkian; Jamal Abdolahpour; Nafiseh Salehi

Volume 27, Issue 108 , September 2018, , Pages 191-200


  Pyroclastic rocks in the Badam area (E-Mahabad, west Azarbaijan Province), are located at the most extreme northern part of the Sanandaj-Sirjan zone. Petrographic studies revealed that they are basanitic in composition and have porphyric and microlithic porphyric textures. Olivine and clinopyroxne occur ...  Read More

Investigation of Magmatic Processes in the Quaternary Volcanism in NW of Ahar: a Geochemical and Isotopic Study

R Dabiri; M.H Emami; H Mollaei; M Ghaffari; M Vosougi Abedini; N Rashidnejad Omran

Volume 23, Issue 90 , March 2014, , Pages 55-62


  Quaternary volcanic rocks are widely developed in NW of Ahar, NW Iran. Based on geochemical data, these rocks mainly consist of alkali basalts, trachybasalts, basaltic trachyandesites and trachyandesites. The major- and trace-element chemistry indicates that the lavas are dominantly alkaline in character. ...  Read More

Magmatic Origin and Tectonic Setting of the Eocene - Oligocene Volcanic and Plutonic Rocks from the Zand-Abad Area, NW Ahar (Tarom-Qaredagh Zone)

Z. Azimzadeh; M. H. Emami; R. Hajialioghli

Volume 20, Issue 79 , January 2011, , Pages 113-120


  The Zand-Abad area is located in NW Ahar of north Azerbaijan. Magmatic rocks in this area consists of granitoids including monzogranite, granodiorite, monzonite and syenogranite as well as mafic rocks mainly diorite and associated extrusive rocks as andesite, trachyandesite, dacite, trachydacite, rhyolite. ...  Read More

The Origin and Evolution of Quaternary Basaltic Magmas in NW Azerbaijan (Burlan to Gonbad) using Sr- Nd Studies

Monireh Kheirkhah; M. H. Emami

Volume 19, Issue 76 , January 2010, , Pages 113-118


  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
