F Sarjoughian; A Kananian; A Esna-Ashari; J Ahmadian

Volume 24, Issue 95 , June 2015, , Pages 145-154

http://dx.doi.org/10.22071/gsj.2015.42422

Abstract
  The Kuh-e Dom intrusion with calc-alkaline nature, in the northeast of Ardestan is located in the central part of the Urumieh-Dokhtar Magmatic Arc and includes the felsic and intermediate-mafic units. The felsic unit consists of monzogranite, granodiorite, quartz monzonite and quartz monzodiorite, whereas ...  Read More

2. Compositional Zoning in Feldspars of the Kuh-e Dom Intrusive Rocks

F Sarjoughian; A Kananian; J Ahmadian

Volume 24, Issue 93 , December 2014, , Pages 133-146

http://dx.doi.org/10.22071/gsj.2014.43554

Abstract
  The alkali feldspars and plagioclases in the Kuh-e Dom intrusive rocks show compositionally and microtexturally zoning structure. The feldspar crystals in the various lithologies such as granite- granodiorite samples, diorite- gabbro samples and relatively high frequency microgranular mafic enclaves ...  Read More

Volume 17, Issue 68 , February 2008, , Pages 140-149

http://dx.doi.org/10.22071/gsj.2009.57853

Abstract
      Paleogene basic to intermediate lava flows of Central Alborz, in the northeast of Qazvin city (Zarjebostan), include trachy-andesite, basaltic trachy-andesite and basaltic andesite. These volcanic rocks are high-K calc-alkaline rocks. Based on the high LILE/HFSE and LREE/HREE ratios ...  Read More

4. Petrology and Geochemistry of Qareaghaj Mafic – Ultramafic Intrusion, NW of Urmia

M. Mirmohammadi; A. Kananian

Volume 18, Issue 69 , February 2008, , Pages 177-191

http://dx.doi.org/10.22071/gsj.2009.57572

Abstract
        Qareaghaj mafic-ultramafic intrusion (QMUI) is located in northwest Iran, 36 km NW from Urmia city. The QUMI is composed mainly of non-mineralized mafic and Fe-Ti-P-rich ultramafic rocks (FTP). The mafic rocks, mainly coarse-grained gabbro, microgabbro, metagabbro and ortho-amphibolite, ...  Read More

5. Petrology and Tectonic Setting of Lakhshak Granodiorite, NW of Zahedan, Iran

Volume 17, Issue 65 , March 2007, , Pages 126-143

http://dx.doi.org/10.22071/gsj.2008.58199

Abstract
       The Lakhshak granitoid pluton which is located at 10 km northwest of Zahedan, has intruded into the Eocene flysch sediments with an elliptical shape and NW-SE direction. This pluton after emplacement has been cut by numerous dykes with NE-SW trend. These dykes comprised about ...  Read More
