Paleoenvironmental model and sequence stratigraphy of the Asmari Formation in southwest Iran

Historical Biology, 2007
The Asmari Formation is a thick carbonate succession of the Oligo-Miocene in southwest Iran (Zagros Basin). The Zagros Basin was a continental margin attached to the eastern edge of Africa throughout the Phanerozoic. The foraminiferal limestone from the Asmari Formation has been studied to determine its microfacies, paleoenvironments and sedimentary ...

STRONTIUM ISOTOPE STRATIGRAPHY OF THE ASMARI FORMATION (OLIGOCENE ‐ LOWER MIOCENE), SW IRAN

Journal of Petroleum Geology, 2007
The Asmari Formation has been studied in the subsurface at the Bibi Hakimeh, Marun and Ahwaz oilfields and in an outcrop section from the Khaviz anticline. It consists of approximately 400 m of cyclic platform limestones and dolostones with subordinate intervals of sandstone and shale.

Depositional environment and sequence stratigraphy of the Oligo-Miocene Asmari Formation in SW Iran

Facies, 2005
The Asmari Formation, a thick carbonate succession of the Oligo-Miocene in Zagros Mountains (southwest Iran), has been studied to determine its microfacies, paleoenvironments and sedimentary sequences. Detailed petrographic analysis of the deposits led to the recognition of 10 microfacies types.

THE ORIGIN OF DOLOMITE IN THE ASMARI FORMATION (OLIGOCENE‐LOWER MIOCENE), DEZFUL EMBAYMENT, SW IRAN

Journal of Petroleum Geology, 2006
Dolomitisation is an important factor controlling reservoir quality in the Asmari Formation in many producing fields in SW Iran. Dolostones have higher average porosities than limestones. Petrographic and geochemical studies have been used to determine the causes of Asmari dolomitisation at the Bibi Hakimeh and Marun fields and at the Khaviz anticline.

Sedimentary facies and sequence stratigraphy of the Asmari Formation at Chaman-Bolbol, Zagros Basin, Iran

Journal of Asian Earth Sciences, 2007
Abstract The Oligocene–Miocene Asmari Formation of the Zagros Basin is a thick sequence of shallow water carbonate. In the study area, it is subdivided into 14 microfacies that are distinguished on the basis of their depositional textures, petrographic analysis and fauna.

Relationship between the sedimentary microfacies and geomechanical behavior of the Asmari Formation carbonates, southwestern Iran

Marine and Petroleum Geology, 2020
Abstract The objective of this paper is to address the impact of texture (and thus the related sedimentary environments and facies and diagenetic overprint) on the geomechanical behavior of the Asmari Formation carbonates. Three sets of data were utilized in this study; i) sedimentological data including thin section petrography, porosity, density ...
