Mineralization and geochemical characteristics of ore-forming fluids in Bahr Aseman area, southeast of Kerman magmatic belt

M. R. Hosseini; S. Alirezaei; J. Hassanzadeh

Volume 27, Issue 105 , December 2017, , Pages 143-156


  The Bahr Aseman volcanic-plutonic complex is located to the southeast of the Kerman magmatic belt. Unlike Kerman magmatic belt which formed and evolved during Cenozoic in a dominantly continental arc and post-collision tectonic setting, Bahr Aseman complex formed during Late Cretaceous in an oceanic ...  Read More

Eocene Masjeddaghi porphyry Cu-Au deposit; an example of island arc porphyry type deposit in NW Iran

S Hassanpour; S. Alirezaei

Volume 26, Issue 104 , September 2017, , Pages 43-58


  The Masjeddgaghi Cu-Au deposit is located to the southeast of the Arasbaran zone, NW Iran, to the south of the Lesser Caucasus. Mineralization in Masjeddaghi is associated with an Eocene dioritic subvolcanic pluton intruded into older volcanic and sedimentary rocks. The Masjeddaghi intrusive body is ...  Read More

Mineralization, Alteration and Ore Fluid Characteristics in Cheshmeh Hafez Base and Precious Metals Deposit, Torud-Chahshirin Range, North-Central Iran

E. Haghighi; S. Alirezaei; E. Ashrafpour

Volume 22, Issue 88 , December 2013, , Pages 99-110


  The Cheshmeh Hafez deposit in Torud-Chahshirin Range, north-central Iran, consists of a polymetal vein mineralization in Cenozoic volcanic host rocks of dominantly basaltic andesite and dacite compositions. The main ore vein, 1800 m long and <1 – 5 m wide, occurs discontinuously in a north-south ...  Read More

Alteration Mapping at Saridoon Porphyry Copper Prospect Using Short Wave Infrared Spectrometry (PIMA), ASTER Satellite Image and XRD

Ahmad Kazemi Mehrnia; I. Rasa; S. Alirezaei; H. Asadi Harooni; J. Karami

Volume 20, Issue 79 , January 2011, , Pages 3-12


  The Saridoon porphyry system is located 3 km northeast of Sarcheshmeh copper mine. Alteration mapping of the area was carried out using PIMA (Portable Infrared Mineral Analyzer) analysis of 145 samples, ASTER satellite images, XRD analysis of 22 samples, field observations and petrographic studies. The ...  Read More

Sulfur, Carbon and Oxygen Isotope Variations of Sulfide and Carbonate in Arghash Gold Prospect, Southwest Neishabour, Northeastern Iran

E. Ashrafpour; K. M. Ansdell; S. Alirezaei

Volume 18, Issue 70 , February 2009, , Pages 173-183


        Arghash gold district includes five gold-bearing vein systems, (Au-ItoAu-V) and one antimony-rich vein hosted by intermediate to silicic volcanic rocks, tuffs, granite, and diorite. Pyrite is the main sulfide mineral consisting of four generations (Py-ItoPy-IV). Py-I toIII are intimately ...  Read More

Ore Geology and Fluid Inclusion Studies of Arghash Gold Prospect, Southwest Neishabour, Northeastern Iran

E. Ashrafpour; S. Alirezaei; K.M. Ansdell

Volume 18, Issue 71 , January 2009, , Pages 129-136


  Arghash gold district is located in the eastern Sabzevar zone. The basement of this zone consists of Precambrian metamorphosed rocks and Paleozoic-Mesozoic epicontinental sediments. The basement is covered by Upper Cretaceous ophiolitic mélange and Tertiary magmatic and sedimentary rocks. Arghash ...  Read More

Fluid Inclusion and Mineralogical Studies of the Sharafabad Epithermal Gold Deposit, NW Iran

S. Ebrahimi; Y. Pan; S. Alirezaei; M. Mehrpartou

Volume 18, Issue 71 , January 2009, , Pages 149-154


  The Sharafabad auriferous epithermal vein system is located in the Alborz-Azarbaijan magmatic assemblage in northwestern Iran. The veins are hosted by Eocene andesitic volcanic and pyroclastic rocks and tuffs. Wall rock alteration includes an inner silicic zone often bordered by argillic and propylitic ...  Read More
