Paleoenvironmental reconstruction of Miocene clastic sedimentary rocks at Kuh-e Asaki and Horgan sections, Neyriz region, Zagros basin

P Gholami Zadeh; M.H Adabi; M Hosseini-Barzi; A Sadeghi; M.R Ghassemi

Volume 26, Issue 101 , December 2017, , Pages 23-34


  The Miocene sediments in Neyriz region crop out  in Zagros Crushed Zone, between Zagros Main Fault and Zagros Ophiolite Zone. For paleoenvironmental studies of these sediments, two stratigraphic sections (Kuh-e Asaki and Horgan sections) have been measured and sampled. The thicknesses of these two ...  Read More

Palynofacies and paleoenvironment of marl segment in Farokhi formation (Central Iran)

M Allameh; B Torabian

Volume 26, Issue 101 , December 2017, , Pages 57-68


  Farrokhi Formation is a Cretaceous rock unit in Central Iran that lithologically contains lime, marl and marly lime accompanied by layers of fossiliferous limestones. This formation lays conformably over the Haft-Tuman Formation, while its upper boundary is disconformable with Chupanan Formation. In ...  Read More

  Carbonate sedimentary rocks equivalent to Asmari Formation containing thick and thin bedded and massive limestones with a thickness of 160m studied in Posht-Darband, Hamadan.  The base of the sedimentary sequence begun with a transgressive conglomeratic horizon. This horizon is composed of rock ...  Read More

Palaeoenvironmental conditions of Gheshlagh coal deposits (Eastern Alborz) based on evidences of petrography and facies

T Rabani; N Taghipour; R Aharipour

Volume 25, Issue 99 , June 2016, , Pages 271-280


  Gheshlagh district contains coal deposits in a large syncline in Shemshak group sediments in East Alborz. To determine the palaeoenvironmental setting of the coal deposits based on organic and mineral components, eleven samples from coal seams from four active mines are collected. Minerals such as quartz, ...  Read More

Recognition of Paleoenvironment of the Ab-deraz Formation in Sanganeh Section based on Palynoligocal Evidence (Dinoflagellate Cysts) and Ostracoda

F Yousefi Moghadam; M Allameh; S.M Hosseininezhad; L Bakhshandeh

Volume 25, Issue 98 , March 2016, , Pages 117-126


  Ab-deraz Formation is one of the Lithostratigraphic units of upper cretaceous the age of which is determined as touronian-santonian in Kopet-Dagh sedimentary basin located in northeast Iran. Its major lithology in Sanganeh section contains Marl, Marly limestone, and gray shales and light green shale ...  Read More

Study of Small Mammal Remains of Quaternary Deposits of Yafteh and Kani Mikaiel Caves and Paleoenvironmental Implications

N Hashemi; A.R Ashouri; M Aliabadian; M.H Mahmoudi Gharaie

Volume 24, Issue 95 , June 2015, , Pages 3-12


  Paleozoology of Yafteh and Kani Mikaiel caves in center and northwest of Zagros Mountains led to the identification of small mammals' assemblage. Taxonomic determination revealed inclusion of four orders of small mammals including:  order Rodentia with families of Muridea, Cricetidae, Calomyscidae, ...  Read More
