A Mosavinia; K Seyed-Emami; A.A Aryai

Volume 23, Issue 91 , June 2014, , Pages 39-45

https://doi.org/10.22071/gsj.2014.43761

Abstract
  The Aitamir Formation follows conformably but with a sharp boundary the dark shales of Sanganeh Formation (Aptian-early Albian) and is followed discontinuously by the whitish marls and chalky limestones of the Abderaz Formation (Turonian-Coniacian). 7 species, 13 genera and 2 subgenera of ammonites are ...  Read More

F. Dabbaghi Sadr; K. Seyed-Emami; M. Majidi Fard

Volume 22, Issue 85 , December 2013, , Pages 35-46

https://doi.org/10.22071/gsj.2012.54019

Abstract
  Upper Jurassic rocks are well developed at the western part of the Binalud Range (northeast Iran). These consist mainly of limestone, marlstone and marl with few intercalations of sandstone and conglomerate. The thickness of this succession in the study section (Bormahan, northwest of Neyshabour) ...  Read More

At Parvar the Dalichai Formation, with a thickness of about 70 m, consist of an alternation of grayish silty marls, marlstones, marly limestone and limestone and is subdivided into 5 members. ...  Read More

Introducing of Calpionellid Zonation at the Jurassic-Cretaceous Boundary in the Shal Section (South-East of Khalkhal)

R. Azimi; K. Seyed-Emami; A. Sadeghi

Volume 17, Issue 68 , February 2008, , Pages 16-25

https://doi.org/10.22071/gsj.2009.57835

Abstract
      The calpionellid biozonation within Shal and Kolur Formations in Shal region, SE Khalkhal are accomplished based on standard biozonation of Allemann et al. (1977).  In this study, 5 biozones are introduced from Tithonian to Hauterivian:biozone. Biozone 1 belongs to Shal Formation ...  Read More
