Abstract
  There are discontinuous outcrops of volcanic rocks in the West Azarbaijan province and in the north of Maku city. These volcanic complex were bimodal and compose of acidic and basic lava and pyroclastic rocks. Mineral chemistry studies show that clinopyroxenes in the studied rocks are diopside. These ...  Read More

Ashraf Torkian; nafiseh salehi

Volume 29, Issue 114 , December 2019, , Pages 15-24

http://dx.doi.org/10.22071/gsj.2018.104562.1303

Abstract
  The Ahmadabad, Tahmoures and Ghareh-toreh volcanoes are part of the volcanic centers located on the Qorveh-Bijar axis and constitute a part of the magmatic outcrops of the northern arm of the Sanandaj Sirjan Zone, Hamadan-Tabriz. Volcanic rocks have basaltic composition and show porphyritic, microlithic ...  Read More

Abstract
  The study area is located in the Ardabil province and in the north east of Meshkinshahr city.More than 200 small and large Eocene age dykes have outcrops in this area with basaltic, tephritic, andesitic and trachy andesit composition. Clinopyroxene, plagioclase, analcime and sometimes coarse olivine ...  Read More

Using Clinopyroxene Composition in the Petrogenesis of the Gabbros from Misho Mountain in SW Marand- Northwestern Iran

Z Azimzadeh; A Jahangiri; E Saccani; Y Dilek

Volume 24, Issue 94 , March 2015, , Pages 61-72

http://dx.doi.org/10.22071/gsj.2015.42743

Abstract
  The Misho gabbroic massif with an east- west trend, 30 Km length and 7 Km wıdth is penetrated in the Infra-Cambrian Kahar  formation. The micro-gabbroic dykes have cut this intrusive massif. Gabbros have homogenous compositions and major phases are plagioclase and pyroxene and minor minerals are ...  Read More
