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

open access: yesOpen 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.

SEISMOGENIC NODES DEFINED BY PATTERN RECOGNITION IN THE CENTRAL PART OF THE ALPINEHIMALAYAN BELT [PDF]

open access: yes, 2016
Information on the areas prone to the strongest earthquakes in a region is very important for knowledgeable seismic hazard and risk assessment. We consider the central part of the Alpine-Himalayan Belt (Caucasus–Kopet Dagh-Alburz) for the recognition of ...

Biostratigraphy of the Cambrian–Ordovician boundary beds at Kopet-Dagh, Iran

open access: yes, 2015
A continuous succession comprising upper Cambrian (Furongian) to Lower Ordovician (Tremadocian) conodont biozones is reported for the first time from the Kopet-Dagh Region of northeastern Iran. Seven biostratigraphical units are recognized, including the Proconodontus tenuiserratus and Proconodontus posterocostatus zones; these two lowermost ...

Sclerobionts on organic substrates from the Late Paleocene Chehel-Kaman Formation, Kopet-Dagh Basin, NE Iran

open access: yesAnnales Societatis Geologorum Poloniae, 2018
Molluscs (oysters and gastropods) of the Late Paleocene Chehel-Kaman Formation, Kopet-Dagh Basin, NE Iran were significantly colonized by sclerobionts. The largest area of the shells studied is covered by various borings. The diversity of macro-bioeroding ichnotaxa is rather high, including Gastrochaenolites Leymerie, 1842; Maeandropolydora Voigt ...
