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 ...

A summary of the Jurassic System in North and East-Central Iran [PDF]

, 2021
The rocks of the Jurassic System in North and Central Iran are represented by very thick sedimentary successions reflecting the deposition during two tectono-stratigraphic megacycles, bounded by three important unconformities.

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.

Study of planktonic morphotype of the Abderaz Formation at type section, Iran [PDF]

, 2009
Abderaz Formation at its type section with an age of Turonian-Early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.

Tectonic Evolution of the Western High Atlas of Morocco: Oblique Convergence, Reactivation, and Transpression

Tectonics, Volume 39, Issue 3, March 2020., 2020
Abstract The High Atlas of Morocco is a double‐vergent mountain belt developed by Cenozoic shortening and inversion of a Triassic‐Jurassic rift. The structural setting, the morphometric features, and the patterns of exhumation through time and space change remarkably both along and across the strike.
