Upper Cambrian–Lower Ordovician conodonts from the southern margin of the Kopet-Dagh Basin, Saluk Mountains, Iran

Alcheringa
A detailed Furongian to Tremadocian conodont biostratigraphy is established from the Saluk Mountains located in southern Kopet-Dagh, northeast Iran. Thirty species assigned to 17 genera were recovered from decimetre-scale limestone beds in a fine-grained

The ammonite family Deshayesitidae in the Kopet Dagh Basin, north-east Iran

Cretaceous Research, 2004
The Iranian part of the Kopet Dagh Basin is located in the north-east of Iran where sedimentation continued throughout Jurassic–Cenozoic times. The ammonite content of the Sarcheshmeh and Sanganeh formations (Lower Cretaceous) has been studied. The following forms are recorded for the first time from the basin: Deshayesites cf.

DIAGENETIC HISTORY OF LATE PALAEOCENE POTENTIAL CARBONATE RESERVOIR ROCKS, KOPET‐DAGH BASIN, NE IRAN

Journal of Petroleum Geology, 2002
The Upper Palaeocene (Thanetian) Chehel‐Kaman Formation in the Kopet‐Dagh Basin of NE Iran is principally composed of carbonates with minor siliciclastics and evaporites. Six stratigraphic sections were measured and more than 1,000 samples were collected for petrographic analysis, together with analyses of carbon and oxygen isotopes and trace element ...

Biostratigraphy of Upper Cretaceous planktonic foraminifera of the Abtalkh Formation in an east-west transect, Kopet-Dagh Basin, northeastern Iran

Micropaleontology, 2020
The Upper Cretaceous Abtalkh Formation of the Kopet-Dagh Basin (northeastern Iran) was studied in four stratigraphic sections (Bahadorkhan, Hammam Galeh, Type section and Shorab). All sections display limestones, shales and calcareous shales.

Seismicity and structure of the Kopet Dagh (Iran, U. S. S. R.)

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975
The region considered under the general term ‘Kopet Dagh’ is located east of the Caspian Sea, and includes Northeast Iran and southern Soviet Turkmenia. The regional tectonics are reviewed with special emphasis on the post-Alpine ‘Diagonal Fault System’.

Two echinoid species from the early Aptian (Early Cretaceous) of the Kopet-Dagh Basin, NE Iran

Zootaxa, 2019
Two echinoid species from the Sarcheshmeh Formation, early Aptian, Lower Cretaceous, of the Kopet-Dagh Basin, NE Iran, are described: a phymosomatoid specimen of Tetragramma sp., and the spatangoid echinoid Miotoxaster collegnii (Sismonda, 1844). This is the first report of echinoids from the Sarcheshmeh Formation from northeastern Iran.
