A biostratigraphic study based on calcareous nannofossils was performed on the chalky limestone from the Abderaz Formation in the Mozduran section (Kopet Dagh basin, NE Iran). Semiquantitative estimates of total nannofossil and single species abundances showed that calcareous nannofossil assemblages are common and their preservation is good. In this study37species have been identified in chalky...

benthic foraminiferal assemblages from maastrichtian strata, gansserina gansseri-abathamphalus mayaroensis planktonic foraminiferal zone, of the abtalkh formation at aitamir section (west of the kopeh-dagh basin) were investigated in order to evaluate the palaeoenvironmental changes (organic matter flux and bottom-water oxygenation). maastrichtian faunal assemblages are well preserved and diver...

abderaz formation is one of the upper cretaceous formations in the kopet-dagh sedimentary basin. a stratigraphic section from the mentioned formation is selected for detailed systematic description with regard to echinoids. numerous well preserved representatives of the families mircrasteridae wright, 1857 and echinocorythidae lambert, 1920 are described from the ghaleh-zoo stratigraphic sectio...

Abderaz The composition of the essential oil obtained from the seeds of Ammi majus L. which collected from province of Khozestan in the southwest area of Iran.The oils was analyzed by gas chromatography mass spectrometry (GC-MS). Twenty - eight components have been identified in the extract of A. majus L. with Toluene (3.766%), Thymol (12.811%), Carvacrol (37.811%) as major components, respecti...

the kopet-dagh basin extended in the north and north east of iran and consists of marine strata from middle jurassic to paleogene time. abtalkh formation is one of the thickest lithostratigraphic units of cretaceous in the kopet-dagh basin and is composed of light gray, green to bluish marl and silty marl. the abtalkh formation conformably overlies the marls and chalky limestones of the abderaz...
