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.

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.

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.

Investigation of Geological Diversity Based on the Degree of Sensitivity and the Amount of Equilibrium and Resilience of the Geosystem (Case study: The Eastern Kopet-Dagh Zone) [PDF]

, 2022
Geomorphological principles show that the earth's surface is not fixed and changes over time. The physical elements of the earth's surface, from microscopic components such as minerals to macroscopic phenomena such as landforms, are all part of ...

Sedimentology and geochemistry of tufa and their relation to hydrochemistry of springs: An example of Abgarm Tufa of Kalat- east of Kopet- Dagh basin [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2017
Tufa is the non- marine carbonates that formed from cold to low temperature freshwater at low depth and low energy flow conditions. Abgarm’s tufa is a typical kind of these deposits.

Petrographical and geochemical evidences for paragenetic sequence interpretation of diagenesis in mixed siliciclastic–carbonate sediments: Mozduran Formation (Upper Jurassic), south of Agh-Darband, NE Iran [PDF]

, 2010
The Upper Jurassic Mozduran Formation with a thickness of 420 m at the type locality is the most important gas-bearing reservoir in NE Iran. It is mainly composed of limestone, dolostone with shale and gypsum interbeds that grade into coarser ...

Sequence and Biostratigraphy of Lower Cenozoic Succession in the Kopet-Dagh Basin, NE of Iran

Open Journal of Geology, 2013
The main purpose of this paper is the sequence stratigraphy and biostratigraphy of lower Tertiary sediments on the base of larger benthic foraminifera in northeast of Iran (Chehel-Kaman Formation). This formation mainly consists of Limestone, dolomite and interbeds of sand, shale and evaporate sediments.

Planktonic foraminiferal turnover across the Cenomanian – Turonian boundary (OAE2) in the northeast of the Tethys realm, Kopet-Dagh Basin

Geologica Carpathica, 2016
Two Late Cenomanian – Early Turonian (C–T) intervals of the eastern part of the Kopet-Dagh basin, NE Iran have been investigated to evaluate the response of planktonic foraminifera to the geological event OAE2. The Gharesu and Taherabad sections with the
