Geothermobarometry of volcanic rocks from N Torud, NE Iran

Najla Saki; Ghasem Ghorbani

Volume 31, Issue 3 , December 2021, , Pages 95-108


  The study area is located in the N Turood, S Shahrood, and NE of Central Iran structural zone. Many basaltic dikes in this area intruded into the Eocene volcanic rocks and they also contain many gabbroic enclaves. Plagioclase (labradorite, bytownite-anorthite), amphibole (calcic, pargasite- magnesiohastingsite), ...  Read More

Mineral geochemistry of clinopyroxene and its application in thermo-barometery of basaltic rocks in Ahmad-Abad, Tahmoures and Gahre-toreh volcanoes (North Qorveh-Kurdistan)

Ashraf Torkian; nafiseh salehi

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


  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

Geochemistry, petrogenesis and tectonic setting of the Sarcheshmeh Eocene mafic lava flows, Southwest of Rafsanjan

S.Z Hosseini

Volume 25, Issue 100 , September 2016, , Pages 209-220


  The Eocene mafic lava flows of Sarcheshmehare cropped out in the southwest of Rafsanjan area at the central part of the Urmia – Dokhtar magmatic belt. The rocks are basalt, basaltic andesite and andesite in composition and consist of clinopyroxene + plagioclase ± olivine ± hornblende phenocrysts. ...  Read More

Back-arc extensional magmatism in the Oligo-Miocene basin of the Northern edge of Central Iran

H Ghasemi; M Rostami Hossuri; M Sadeghian; F Kadkhodaye Arab

Volume 25, Issue 99 , June 2016, , Pages 239-252


  Subduction of the Neo–Tethyan oceanic lithosphere beneath the southern edge of the Central Iran caused development of extensional back-arc basins behind the Urumieh–Dokhtar magmatic belt during Mesozoic and Cenozoic. Some researchers have noted formation of the oceanic back-arc basins in ...  Read More

Geology and Petrology of the Soltan Maydan Basaltic Complex in North-Northeast of Shahrud, Eastern Alborz, North of Iran

M Derakhshi; H Ghasemi; T Sahami

Volume 23, Issue 91 , June 2014, , Pages 63-76


  The Soltan Maydan Basaltic Complex indicates the most important, thickest, and most voluminous early Paleozoic magmatic activity in Iran outcropping in the eastern Alborz structural zone, in the north-northeast of Shahrud. This complex overlies the late Ordovician Ghelli Formation and is overlain by ...  Read More

Various stages of Sulfide Mineralization in Sargaz Volcanogenic Massive Sulfide Deposit, Northwest Jiroft, Southern Sanandaj-Sirjan

zahra badrzadeh; M. Sabzehei; E. Rastad; M. H. Emami; D. Gimeno

Volume 19, Issue 76 , January 2010, , Pages 85-94


  The Sargaz massive sulfide deposit is situated near Jiroft (south-east Kerman), in the southern Sanandaj-Sirjan Zone. The host rocks are Upper Triassic to lower Jurassic(?) pillow basalt. The occurrence of mineralization in basaltic to basaltic andesite, the existence of Jaspilite and Fe-Mn horizons ...  Read More

Petrology of Quaternary Basalts of Tabas (East of Iran)

S. M. Hashemi; M. Emami; M. Vossoughi Abedini; M. Pourmoafi; M. Ghorbani

Volume 17, Issue 68 , February 2008, , Pages 26-39


  In southeastern Tabas there is a 400 square kilometer area of Quaternary basalts, which is geologically located in Lut zone. According to petrographic studies and EMPA analysis, the textures of these rocks are generally porphyric and some times aphyric. The phenocrysts of these basalts are generally ...  Read More
