Shima Shomali; Mansour Ghorbani; Mohamad Reza Ghasemi

Articles in Press, Accepted Manuscript, Available Online from 21 June 2024

https://doi.org/10.22071/gsj.2023.410160.2107

Abstract
  The Marphioon pluton in the central part of Urmia-Dokhtar magmatic arc is among the Neotethyan oceanic lithosphere subduction-related intrusions. The composition of this pluton changes from granodiorite to tonalite. Marphioon granitoid gives rise to contact aureole zone with different peripheral thicknesses. ...  Read More
