Short-term seismic crustal deformation of Iran [PDF]

Annals of Geophysics, 2014
In this paper the short-term seismic deformation of Iran is determined by the earthquake moment tensor summation. The study areas include the Alborz, Kopeh-Dagh, eastern Iran, Makran and Zagros orogenic belts.

Palynostratigraphy of the Sanganeh Formation at the East and Central Kopeh-Dagh Basin based on dinoflagellate cysts [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2015
The Sanganeh Formation (Lower Cretaceous) has cropped out across the Kopeh-Dagh Basin. The formation conformably overly the Aptian Sarcheshmeh Formation and is in turn overlain conformably by glauconitic sandstone of the Aitamir Formation. The considered

Strike-slip faulting, rotation, and along-strike elongation in the Kopeh Dagh mountains, NE Iran [PDF]

Geophysical Journal International, 2006
SUMMARY The Kopeh Dagh is a linear mountain range separating the shortening in Iran from the stable, flat Turkmenistan platform. In its central part is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometres in the geomorphology and geological structure.

Quaternary slip rates along the northeastern boundary of the Arabia-Eurasia collision zone (Kopeh Dagh Mountains, Northeast Iran) [PDF]

Geophysical Journal International, 2009
P>The Kopeh Dagh is accommodating a large portion of the northward motion of central Iran with respect to Eurasia, involving a major right-lateral strike-slip fault system (Bakharden-Quchan). This fault system corresponds to the northeastern boundary of the Arabia-Eurasia collision, and can be considered as a lithospheric-scale tectonic feature.

Assessment of Climate Change Impacts on the Efficiency of Kopeh Dagh Conserved Area (Case study: Persian Gazella) [PDF]

محیط زیست و مهندسی آب
Persian Gazelle (Gazella subgutturosa subgutturosa) is one of the most important herbivores of the steppes of Iran, which is found in different plains and desert areas. Today, the distribution of this species is limited to special areas, which has caused

Significance of ichnofossils in high resolution sequence stratigraphy: Upper Maastrichtian, Kopeh- Dagh Basin, NE Iran

, 2012
This study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the Kalat Formation (Upper Maastrichtian) in the Central Kopeh- Dagh Basin (NE Iran), Dareh-Gaz section. Field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in ...

Integrated seismic and geodetic strain analysis in the Kopeh Dagh Belt (Northeastern Iran): Implications for intraplate deformation

Journal of Structural Geology
The Kopeh Dagh mountain belt is one of the most tectonically and seismically active regions in the central Eurasian collision zone, having experienced numerous moderate to large earthquakes (Mw ≥ 5.1) in recent decades. This study presents a novel structural and geodynamic analysis of ongoing deformation in the Kopeh Dagh Belt through the integration ...
