Volume 30, Issue 118 , January 2021, , Pages 25-36

https://doi.org/10.22071/gsj.2020.222846.1770

Abstract
  The peridotites from Marivan-Kamyaran ophiolite suite (MKO), outer Zagros ophiolite belt, western Iran, are studied for the petrological and geochemical characteristics. Both mantle and crustal peridotites are present in the Marivan-Kamyaran ophiolitic sequence. Extensive compositional variations in ...  Read More

Volume 26, Issue 104 , September 2017, , Pages 149-162

https://doi.org/10.22071/gsj.2017.50183

Abstract
  The Lakhshak granodiorite body with Oligo-Miocene age crops out in flysch sediments of northwest of Zahedan. This body has been intruded by dykes with variable color indices ranging from mesocratic to melanocratic, and NE-SW trend. Based on field observations, , melanocratic dykes have cut mesocratic ...  Read More
