First report of Mid Ordovician (Darriwilian) cephalopods from the Saluk Mountains, southern Kopet-Dagh Region, north-east Iran

Bulletin of Geosciences, 2021
An assemblage of orthoconic cephalopods collected from oolitic ironstones at the base of the Pelmis Formation (New) of the Saluk Mountains of the southern Kopet-Dahg Region of north-eastern Iran indicate that the base of the Pelmis Formation is likely to

Does the intensive grazing and aridity change the relations between the dominant shrub Artemisia kopetdaghensis and plants under its canopies?

Ecology and Evolution, Volume 11, Issue 20, Page 14115-14124, October 2021., 2021
The manuscript is based on a field study, aiming to compare the canopy effects of an unpalatable dominant shrub (Artemisia kopetdaghensis) in the conditions of biotic stress, represented by intensive grazing and abiotic stress, represented by severe aridity.

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.

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

A story from the Miocene: Clock‐dated phylogeny of Sisymbrium L. (Sisymbrieae, Brassicaceae)

Ecology and Evolution, Volume 11, Issue 6, Page 2573-2595, March 2021., 2021
Morphological variability and imprecise generic boundaries have hindered systematic, taxonomical, and nomenclatural studies of Sisymbrium L. (Brassicaceae, Sisymbrieae DC.). The present study placed the biological history of Sisymbrium L. into time and space and rendered the tribus Sisymbrieae as monotypic.

Paleoecology of the Maastrichtian and Danian sediment at North of Central Alborz, Iran, based on Planktonic foraminifera [PDF]

, 2010
In order to study the fossil contents of the Ziarat-kola section for biostratigraphical purposes the 212 meters was sampled at Central Alborz. The sequence is mainly made up of monotonous grey- green to light grey marl.

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).
