Biostratigraphy of the upper part of Aitamir Formation based on calcareours nannofossils, Cherli section (NW Kopet-Dagh) [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2017
Introduction The Kopet-Dagh sedimentary basin is located in north-east Iran, southern Turkmenistan and Afghanistan and is composed of Mesozoic and Cenozoic sedimentary successions. Fifteen formations have been introduced in the Kopet-Dagh Basin.

Recognition of Oil Traps in the Kopet-Dagh Basin (Northeastern Iran) Using Fusion of Seismic Attributes, Petrophysical Logs and Geological Data [PDF]

Journal of Petroleum Science and Technology, 2022
Integrated analysis of oil traps, especially those related to facies changes, is far more complicated than reservoirs related to structural traps. The most useful way to identify these complex subsurface structures directly related to facies change is to

Geochemical and Isotopic Evolution of Late Oligocene Magmatism in Quchan, NE Iran

Geochemistry, Geophysics, Geosystems, Volume 22, Issue 11, November 2021., 2021
Abstract Magmatic activity that accompanied the collision between Arabia and Eurasia at ∼27 Ma, provides unique opportunities for understanding the triggers and magma reservoirs for collisional magmatism and its different styles in magmatic fronts and back‐arcs.

Ecological and geological processes impacting speciation modes drive the formation of wide‐range disjunctions within tribe Putorieae (Rubiaceae)

Journal of Systematics and Evolution, Volume 59, Issue 5, Page 915-934, September 2021., 2021
Wide‐range geographically discontinuous distributions have long intrigued scientists. We explore the role of ecology, geology, and dispersal in the formation of these large‐scale disjunctions, using the angiosperm tribe Putorieae (Rubiaceae) as a case study. From DNA sequences of nuclear ITS and six plastid markers, we inferred a phylogeny, obtained an

Slip‐Rate on the Main Köpetdag (Kopeh Dagh) Strike‐Slip Fault, Turkmenistan, and the Active Tectonics of the South Caspian

Tectonics, Volume 40, Issue 8, August 2021., 2021
Abstract We provide the first measurement of strike‐slip and shortening rates across the 200‐km‐long right‐lateral strike‐slip Main Köpetdag Fault (MKDF) in Turkmenistan. Strike‐slip and shortening components are accommodated on parallel structures separated by ∼10 km.

Biostratigraphy of the Tirgan Formation in the Kopet-Dagh basin:Stratigraphic sections of the Tirgan village and Amirabad [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2019
The Lower Cretaceous successions of the NE Iran in the sedimentary Kopet-Dagh basin are result from transgression of the Berriasian-Barremian marine, which are deposited after first erosional cycle (Late Jurassic-Early Cretaceous).

Regional Factors Controlling the Type of Pliocene Deposits in the Southeastern Caspian Basin, NE Iran: Implication for Tectono-stratigraphic Analysis [PDF]

Journal of Petroleum Science and Technology, 2020
Providing information about the role of the major elements controlling the type of Pliocene deposits in the south­eastern part of the Caspian Basin by assessing regional and global parameters is very important to demonstrate the relationship between the ...

Biostratigraphy of the Cretaceous deposits based on ammonites in the southwest of Qayen area (Qumenjan section) [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2021
Ammonite biostratigraphy could be used in age determination and correlation of rock units in different sedimentary basins. Qumenjan section with 125 meters thickness is mainly formed by grey sandy limestone with grey and thick-bedded limestone ...

FIRST RECORD OF CALCAREOUS GREEN ALGAE (DASYCLADALES, HALIMEDACEAE) FROM THE PALEOCENE CHEHEL KAMAN FORMATION OF NORTH-EASTERN IRAN (KOPET-DAGH BASIN)

Acta Palaeontologica Romaniae, 2021
The micropalaeontological inventory of the shallow-water carbonates of the Paleocene Chehel-Kaman Formation cropping out in the Kopet-Dagh Basin of north-eastern Iran is poorly known. New sampling has evidenced for the first time the occurrence of layers

Calcareous nannofossil biostratigraphy of Sarcheshmeh and Sanganeh formations in the west of Kopet-Dagh Basin, Sheikh Section [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2015
The Kopet-Dagh Basin is located in the north and north east of Iran, within the border triangle of Iran, Turkmenistan and Afghanistan. Sediments of Cretaceous age are well exposed in this basin.
