Stratigraphy and Palaeontology
Statistical analysis of apertural protective structures of the planktonic foraminifera at Abderaz Formation ( Turonian-Earliest Campanian), east of the Kopeh-Dagh basin, (NE Iran)

Meysam Shafiee Ardestani; Mohammad Vahidinia

Volume 29, Issue 113 , November 2019, , Pages 229-244


  Apertural protective structures of the planktonic foraminifera in the Abderaz Formation have been studied in order to determine seal level changes in 4 stratigraphical sections including: Abderaz village, Muzduran pass, Padeha village and Shorb . Lithological study of the Abderaz Formation shown that ...  Read More

Biostratigraphy and paleoecology of Abderaz Formation in Chahchaheh section, East Koppeh Dagh based on Ostracods

S. Sanjary; F. Hadavi; M. Notghi Moghaddam; M. Allameh

Volume 27, Issue 108 , September 2018, , Pages 75-82


  In the present study the Abderaz Formation ostracods were investigated. The thickness  of the formation in this section is 385m, and consists of shale and marl together with three horizons of chalky limestone. Paleontological studies led to identification of 16 genera and 51 species of ostracods ...  Read More

The Cenomanian – Turonian boundary oceanic anoxic event in East of Kopet-dagh basin (Amirabad section) with emphasis on calcareous nannofossils

N Mousavi; A L.Kani; A Mosavinia

Volume 26, Issue 101 , December 2017, , Pages 265-276


  In this study the succession comprising Aitamir and Abderaz Formation boundary is investigated along Amir Abad section in eastern Koppeh-Dagh region. Based on Calcareous nannofossils and NC biozonation scheme, Late Albian to Late Turonian time of deposition is estimated for the measured succession. There ...  Read More

Planktic Foraminiferal Palaeobathymetry of the Santonian-Campanian Boundary in Eastern Kopeh-Dagh Basin, Northeastern Iran

M Shafiee Ardestani; M Vahidinia; A Sadeghi

Volume 24, Issue 94 , March 2015, , Pages 45-64


  In this research, we documented a paleontological study on the basis of planktic foraminifera, in five stratigraphic sections (Type, Padeha village, Shorab, Abderaz village and Qarehso) across the Santonian-Campanian transitional boundary in the eastern Kopeh-Dagh sedimentary basin. In all sections, ...  Read More

Biostratigraphy of the Abderaz Formation at Type Section Using Planktonic Foraminifera

M. Shafiee Ardestani; E. Ghasemi-Nejad; H. Vaziri Moghaddam

Volume 19, Issue 75 , January 2010, , Pages 25-34


  In order to study the fossil contents of the Abderaz Formation for biostratigraphical purposes the 300 meters thick section was sampled at type section. The sequence is mainly made up of grey shales and marls with two units of chalky limestone in upper part. The lower contact of the formation with Aitamir ...  Read More

Study of Planktonic Foraminifera and Biozonation in Abderaz Formation

L. Bakhshandeh; A. Aghanabati; F. Keshani; T. Mohtat

Volume 16, Issue 64 , March 2007, , Pages 126-135


       To revise the Abderaz Formation in Koppeh-Dagh basin, its type section was studied considering stratigraphical properties. The main lithology of Abderaz Formation includes gray to blue shale with a thickness of 286.86 meters. This Formation has an attitude of N 45˚ W and 80˚ ...  Read More
