The Zayanderud metamorphic complex, North of Shahrekord: two entirely different interpretations of a basement complex in the Najafabad and Chadegan maps

R. Jamali Ashtiani; J. Hassanzadeh; M. Rahgoshay

Volume 26, Issue 104 , September 2017, , Pages 95-102

https://doi.org/10.22071/gsj.2017.50174

Abstract
  Two different ages of Precambrian and Jurassic are considered for the Zayanderud metamorphic complex in the Najafabad and Chadegan geology maps, respectively. This disagreement has made these two maps to be the most incompatible adjacent maps. The metamorphic complex is nonconformably covered by fossiliferous ...  Read More

Geochemistry and Petrogenesis of the Orzuieh Volcanic Sequence (South of Iran)

I. Monsef; M. Rahgoshay; M. H. Emami

Volume 21, Issue 82 , December 2011, , Pages 65-76

https://doi.org/10.22071/gsj.2011.54442

Abstract
  The Late Jurassic to Early Cretaceous Orzuieh volcanic sequence is exposed in the southern part of the Sanandaj – Sirjan Zone. Major and trace element geochemistry shows magma evolution from the transitional to the calc-alkaline series. Clinopyroxene compositions are similar to their composition ...  Read More

Geochemistry and Petrogenesis of Andesitic-Basaltic Series in Siah-Cheshmeh Ophiolite, NW of Khoy

M. Poormohsen; M. Rahgoshay; I. Azadi; H. Shafaii Moghadam

Volume 20, Issue 77 , January 2010, , Pages 131-136

https://doi.org/10.22071/gsj.2010.55358

Abstract
  The Siah-Cheshmeh ophiolites at the north-northwest part of the Khoy ophiolites show a dismembered pile of metamorphic units, mantle sequence, and basaltic-andesitic lavas associated with Late Cretaceous pelagic limestones and cherts.  The basaltic-andesitic lavas can be divided into alkaline and ...  Read More
