Petrography and geochemistry of Silurian Niur sandstones, Derenjal Mountains, East Central Iran: implications for tectonic setting, provenance and weathering
Petrographical and geochemical studies of Silurian Niur sandstones, Derenjal Mountains, Central
Iran, were carried out to infer their provenance and tectonic setting. Modal analysis data of 37 medium sand size and ...

Systematic notes on Burdigalian Echinoids from the Qom Formation in the Bagher Abad area, Central Iran
Echinoids fauna are common and distributed in the Lower Miocene deposits of the Bagher Abad area, northeast Isfahan, Central Iran. There are six Echinoid taxa belonging to the Echinoidea Class that can be described as: Clypeaster intermedius...
Biostratigraphy of Large Benthic Foraminifera from Cuisian and Bartonian Limestones from the Torbat-e- Heydarieh region -Central Iran-
- Heydarieh -central Iran-. Our systematic survey revealed well- preserved alveolinids and nummulitids and led to the identification of 14 species and three subspecies. because the section analyzed has never been studied before we provied a detailed...
Problems of stratigraphic correlation of the Permian-Triassic transitional beds in the Transcaucasus and Central Iran
Permian–Triassic boundary sections in Iran belong to the best exposures of this important time interval worldwide and work as a standard for the transition beds in the Tethyan Realm. Increasing interest in these sections ...
Geometric morphometric study of two species of the psammophilous genus Erodiontes (Coleoptera: Tenebrionidae) from the Lute desert, Central Iran
A geometric morphometric study of the genus Erodiontes was carried out using the Elliptic
Fourier method to demonstrate the effect of vicariance on populations of these
psammophilous species. Four populations ...
Late Santonian-Early Maastrichtian calcareous nannofossils from marly deposits near Kerman (Central Iran)
in the Kerman basin,
Central Iran. In most parts of Central Iran, the Upper
Cretaceous sequence is complete and continuous and is divided
into two groups: Cenomanian–Touronian flysch and
Campanian–Maastrichtian flysch. Flyschs...
PALAEOENVIRONMENT AND BASIN ARCHITECTURE OF THE LOWER JURASSIC AB-HAJI FORMATION, EAST-CENTRAL IRAN
The Lower Jurassic Ab-Haji Formation of the Kalmard, Tabas and Lut blocks, east-central Iran, has been
studied using an integrated stratigraphic-sedimentologic approach. The Ab-Haji Formation is mostly composed of greenish sandstones...
Calcareous nannofossil biostratigraphy of the Qom Formation in Central Iran
The Qom Formation has an extensive distribution in northern
to central Iran, and it is comprised of thick successions
of marine marlstones, limestones, gypsum, and siliciclastics.
This formation, which is composed of six lithostratigraphic...
