Volume 32, Issue 4 , December 2022, , Pages 163-176


  Numerous vertebrate footprints have been found in the dislocated sandstone slabs in the Mashhad city, northeast Iran. Neogene sediments of Chenaran township are supposed to be provenance of the studied slabs. Identified footprints includes artiodactyl tracks as ichnotaxa Bifidipesvelox, Lamaichnum guanicoe, ...  Read More

Facies changes and sedimentary environment in a pre-arc basin (Nazarkardeh Formation, Kopeh Dagh sedimentary basin, northeastern Iran)

Volume 32, Issue 4 , December 2022, , Pages 379-394


  A unique basement of Kopeh  Dagh sedimentary basin is located and investigated in Agh-darband area, northeastern Iran. The second formation of the Agh- darband group, the Nazarkardeh Formation is cropped out in the area by carbonate and volcanogenic successions. This Formation with Anisian age is ...  Read More

Seismotectonics of the East Alborz and Kopeh- Dagh zones using local seismic network data

M. Kouhpeyma; M. Talebian; L. Chen; A. Ghods; M. Ghorashi

Volume 31, Issue 1 , June 2021, , Pages 199-208


  The Kopeh Dagh and Binalud-Alla Dagh mountains are important structural elements located in the northeastern boundary of Arabia-Eurasia collision zone. Due to existence of large cities with a long history of civilization, there is a relatively rich body of data on historical seismicity in this area. ...  Read More

Identification of Falling Stage System Tract in fluvial successions, an example from Shurijeh Formation

Gholamreza Hosseinyar; Reza Moussavi-Harami; Iraj Abdollahi fard; Asadollah Mahboubi; Hamidreza Mosaffa

Volume 29, Issue 113 , November 2019, , Pages 283-290


  Identification of falling-stage system tracts (FSST) in sequence stratigraphy has important role in sequence boundary recognition and exploration researches. However, formation and preservation chance of its related facies in the fluvial successions is very low. This study pays to signs and evidence ...  Read More

Ammonites of the Aitamir Formation in the Zawin Section (E Kopeh Dagh) and the First Record of Marine Dinosaurs from the Cretaceous of Iran

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

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


  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

Microbiostratigraphy of the Aitamir Formation in North West of Kopeh Dagh Basin (Maraveh Tappeh Section)

M. Motamedalshariati; A. Sadeghi; H. Vaziri Moghadam; R. Moussavi Harami

Volume 22, Issue 85 , December 2013, , Pages 225-236


  A stratigraphic section in west of Maraveh Tappeh town has been selected and measured in order to study the Aitamir Formation in north west of Kopeh Dagh. The Aitamir Formation with 1070 m thickness, consists of sandstone in the lower part and shale and marl in the upper part. The lower and upper boundaries ...  Read More

Comparison of Seismic, Geodetic and Geologic Moment Rates in Eastern Alborz and Kopeh Dagh

M. Talebian

Volume 22, Issue 86 , December 2012, , Pages 183-192


  The north east of Iran, extending from central Alborz to Kopeh Dagh Mountains, is one of the most seismically active regions of Iran. Several large and ancient cities are located in this region and thus provide relatively reach documented history of earthquakes. Numerous active faults have been known ...  Read More

Study and Correlation between Lower Cretaceeous Deposites in Koppeh-Dagh and Central Iran Basins
