The evolution of ore-forming fluids and genesis of Nukeh iron deposit, North Semnan based on evidence from fluid inclusions and S, C, O stable isotopes

S. Esmailnezhad; N. Taghipour; A. A. Hassannezhad

Volume 26, Issue 103 , June 2017, , Pages 309-322

https://doi.org/10.22071/gsj.2017.46603

Abstract
  The Nukeh iron deposit is situated at the north of Semnan and at south of Central Alborz structural zone. Volcano-pyroclastic rocks with Eocene age are the host of this deposit. Iron mineralization occurs as massive, disseminated, vein and breccia types in the Nukeh deposit and magnetite, hematite, pyrite, ...  Read More

Genesis of the Hamyerd iron Deposit, NE Semnan: Using Fluid Inclusion and Stable Isotope (S, C, O) Studies

M Hajibahrami; N Taghipour; G Ghorbani

Volume 25, Issue 97 , December 2016, , Pages 61-70

https://doi.org/10.22071/gsj.2015.41366

Abstract
  The Hamyerd iron deposit is located in the northeast of Semnan in the boundary of the southern Alborz and Central Iran structural zones. A sub-volcanic body of monzonite and monzodiorite composition intruded limestone and pyroclastic rocks (equivalent to the middle Eocene Karaj formation). The iron mineralization ...  Read More

Mineralogy, Geochemistry and Origin of Iron Deposits in North of Semnan

A. R. Ghiasvand; M. Ghaderi; N. Rashidnejad-Omran

Volume 18, Issue 72 , January 2009, , Pages 33-44

https://doi.org/10.22071/gsj.2010.57133

Abstract
  The iron deposits in north of Semnan are located in the south of Central Alborz structural zone. Stratigraphically, the area consists of Paleozoic to Quaternary rock series exposures. The area has been affected by Semnan, Darjazin, Attari and Diktash faults. An intermediate to acidic granitoid body of ...  Read More
