     The study area is located in the northeast of Iran. Miankuhi Formation is 500m thick and comprises homogeneous shales, brown granular sandstone and siltstone. In this study, 45 samples were taken from Miankuhi shales and sandstones in order to determine their tectonic origin by using a polarizing microscope. Samples were analysed by X-Ray Fluorescence (XRF) method to determine their chemical compositions and tectonic origin. Twelve shale and siltstone samples were also analysed by the X-Ray Diffraction method with the aim of identifying their mineral composition. According to the investigations conducted, the type of sandstone is greywackes. Based on XRD results, quartz, albite, orthoclase, calcite, kaolinite, and illite have existed in shales and siltstones. Chemical analysis of the rocks indicated the source of these clastic rocks as oceanic arc areas and active peripheries of a landmass. The corrosive rocks of this formation are believed to originate from intermediate felsic igneous rocks and to a lesser extent from clastic quartz-containing rocks in the region.  Manuscript profile

  Kopet-Dagh basin is located in north and northeast of Iran. Khangiran Formation is one of the most importantformations of Paleogene deposits. For study of Khangiran Formation, Chehelkaman Syncline section wasselected. This section located in southwest of Sarakhs city, east of Kopet-Dagh basin. Thickness of this section is136 meters and lithology of this section composed alternation of olive green Marl and limy yellow Marl. In thisresearch foraminifera fauna of Khangiran Formation was studied. The age of this section is Early-MiddleEocene, and planktonic foraminifera fauna of this section shows anomaly. Based on this anomaly, lack ofMorozovellids, that are index fossils of Eocene, was observed. Eutrophic condition of this Formation as for theplanktonic and benthonic foraminifera study is the reason of this subject that it's the result of changes in thepaleoceanographic conditions such as situation of stratification of water column and nutrient changes. As far theMorozovellids can't accordance with eutrophic condition, lack of the species mans of this genus observed forKhangiran Formation. Khangiran Formation condition is comparable with Caucasus basin and this subject can beindicating of same condition of this two basin at least during the Eocene time. Manuscript profile
