Fatemeh Esmaeili; Fardin mousivand; Mahmoud Sadeghian; Seyed Mehran Heidari

Volume 32, Issue 4 , December 2022, , Pages 305-318

https://doi.org/10.22071/gsj.2022.293355.1919

Abstract
  Miandasht copper deposit is located in 110 km east of Shahrood, 24km north west of Abbasabad, and in the Cenozoic volcanic belt of north of Central Iran zone. The major rock units of the study area have Eocene age and include submarine flows (andesite, basalt, and trachyandesit), pyroclastic (tuff breccia ...  Read More

Geology, structure and mineralization of Cu (± Au) hydrothermal-magmatic deposits of Saveh-Razan region

Seyed Mehran Heidari; Sara Safavy; Afshin Akbarpour; Azra Hassanlou; Bahram Mohaghegh

Volume 32, Issue 2 , July 2022, , Pages 89-104

https://doi.org/10.22071/gsj.2021.276571.1894

Abstract
  Saveh-Razan copper (± gold) area, with WNW direction in the northwest of Urmia-Dokhtar magmatic belt, with the highest reaction to right-sided shear zones and structural trend change during the Oligomyocene, leads to the placement of semi-deep Oligomyocene diorite massifs in shallow rock depths. ...  Read More

Geology and mineralization of Zavarian Au-(Cu) deposit (Qom-Salafchegan)

Elnaz Zahmatkesh; Seyed Mehran Heidari

Volume 30, Issue 117 , December 2020, , Pages 39-50

https://doi.org/10.22071/gsj.2020.203242.1707

Abstract
  Zavarian gold occurrence formed within andesitic volcanic units in northwestern Iran. The volcanic complex is in fact a part of magmatism related to Urumieh-Dokhtar magmatic belt crosscutting northwestern rim of Central-Iran zone. This system is a part of the volcanic-sedimentary sequence of the Qom ...  Read More

Sediment-hosted epithermal gold mineralization at Arabshah, SE Takab, NW Iran

S. M. Heidari; M. Ghaderi; H. Kouhestani

Volume 27, Issue 105 , December 2017, , Pages 265-282

https://doi.org/10.22071/gsj.2017.53971

Abstract
  Arabshah gold deposit formed through hydrothermal activity with an age of ~11 Ma (based on zircon U-Pb dating by LA-ICP-MS), in northwestern Iran. This hydrothermal activity is a part of the Urumieh-Dokhtar magmatic arc (UDMA), leading to mineralization in this area, similar to Zarshouran, Aghdarreh ...  Read More

Touzlar Epithermal Au-Ag (Cu) Deposit, Subvolcanic Intrusion-related of Intra-arc Extensional Setting, Northwest Mahneshan, Iran

S.M Heidari; M Ghaderi; H Kouhestani; M Hosseini

Volume 24, Issue 94 , March 2015, , Pages 329-349

https://doi.org/10.22071/gsj.2015.42948

Abstract
  The Touzlar epithermal gold deposit formed within the high-K calc-alkaline (shoshonitic) andesitic volcanic units in northwestern Iran. The volcanic complex is in fact a part of magmatism related to the Urumieh-Dokhtar Magmatic Belt crosscutting northeastern rim of the Sanandaj-Sirjan Metamorphic-Magmatic ...  Read More
