R Farokhnejad; B Esfandiari; A Motamed

Volume 26, Issue 101 , December 2017, , Pages 211-218


  In this paper the Fajan Formation of Paleocene age with a thickness of 172.5 meters is studied in northwest Shahroud (Eastern Alborz). Main lithology of this formation, at the studied section, consists of conglomerate and sandstone. The formation disconforably overlain  upper Cretaceous limestones ...  Read More

Z Hamidi Beheshti; H Alimohammadian; M Talebian; A Shahidi; M.R Ghassemi

Volume 24, Issue 95 , June 2015, , Pages 153-164


  Geomagnetism is one of the most applied techniques of geophysics in geology. Today, this method is applied in different disciplines such as Magnetic fabric of rocks, palaeomagnetism and environmental magnetism. Each of these magnetic methods is suitable for a particular lithology. Therefore, the potential ...  Read More

Provenance of the Givetian-Frasnian Sandstones in the Kuh-e-Tizi Section (Northeastern Kerman), Central Iran

S. H. Hejazi; M. H. Adabi; S. R. Moussavi Harami

Volume 20, Issue 79 , January 2011, , Pages 157-164


  The Givetian-Frasnian sandstones in the Kuh-e-Tizi section (25 km NE Kerman), unconformably overlie the Upper Cambrian Kuhbanan and underlie the Lower Carboniferous Hutk Formations respectively, in southeastern Central Iran. Petrographical data show that these sandstones are well-sorted, sub-angular ...  Read More
