M. Yazdi; H. R. Pakzad; M. Mashkour; R. Elhami; M. Javeri; F. Biglari

Volume 19, Issue 73 , January 2009, , Pages 177-186

https://doi.org/10.22071/gsj.2010.57223

Abstract
  Determining and studying collected lithic assemblages, biota remains and deposited beds (regarding to sedimentology) of two rock shelters in the age of Late Pleistocene to recent interval in central Iran were the aims of this research. Mobarekeh (Qaleh Bozi) and Yekeh Chah (near Golpayegan) are two sites ...  Read More

Thalassinoides Ichnofabric from Oligocene Sediments in the Ali Abad Section, Qom Area, Central Iran

N. Abbassi; A. Amini

Volume 18, Issue 69 , February 2008, , Pages 86-101

https://doi.org/10.22071/gsj.2009.57542

Abstract
        The Thalassinoides bearing calcareous sandstone and sandy limestones of Oligocene age unconformably overlay the Eocene volcaniclastic rocks and gradually pass into the lacustrine sediments (Miocene? in age) in the study area. These layers are dominated by Thalassinoides ...  Read More

Geochemistry and Petrogenesis of an Alkaline-Calc Alkaline Volcanic Suite North Central Iran: The Role of Crystal Fractionation and Enrichment Processes in a Back-arc Environment

F. Tutti; S. Yazdani; K. Bazargani-Guilani

Volume 17, Issue 67 , February 2008, , Pages 210-223

https://doi.org/10.22071/gsj.2009.57832

Abstract
        South Kahrizak volcanic rocks with Eocene age are located in the north part of Central Iran. These rocks are mainly composed of pyroclastics (tuff and ignimbrites) and lava flows (rhyolite, trachyandesite, basaltic trachyandesite and basalt). Petrographic evidence such as: zoning, ...  Read More
