Geochemical evaluation and source rock zonation by multi-layer perceptron neural network technique: a case study for Pabdeh and Gurpi Formations-North Dezful Embayment (SW Iran)

open access: yesJournal of Petroleum Exploration and Production Technology, 2023
In this study, using a multi-layer perceptron neural network (MLPNN) model, total organic carbon (TOC) and hydrogen index (HI) values for Pabdeh and Gurpi Formations in the oil fields of Naft Sefid (NS-13), Kupal (KL-36, KL-38, and KL-48) and Palangan ...

High‐Resolution Local Earthquake Tomography Beneath the Zagros Simply Folded Belt (SFB): Implications for an Inhomogeneous Low‐Velocity Layer and Diapirism in the Upper Crust

open access: yesEarth and Space Science, Volume 10, Issue 8, August 2023., 2023
Abstract Hormuz salt formation is considered the origin of the evaporated salt deposits in the Zagros and its ductile behavior has been known as the reason for the inhomogeneous deformation in the Zagros. However, our knowledge about this formation has been limited to the salt domes on the surface.

Mineralogy, geochemistry and depositional environment of phosphates in the Pabdeh Formation, Khormuj anticline, SW of Iran

open access: yesEnvironmental Earth Sciences, 2022
Abstract Phosphate deposits are found in the Khormuj anticline at the end of the Folded Zagros Zone of Iran and are enriched in REE and trace metals. Field survey, petrography, X-ray diffraction and whole-rock geochemistry were used to determine the petrogenesis of these phosphate deposits and evaluate the mechanisms of trace metal enrichment ...

Palaeocene to Miocene southern Tethyan carbonate factories: A meta‐analysis of the successions of South‐western and Western Central Asia

open access: yesThe Depositional Record, Volume 8, Issue 3, Page 1031-1054, September 2022., 2022
One hundred and forty‐four sections of shallow‐water carbonates, deposited between the Palaeocene and the Miocene, from the Levant to the Himalaya, have been investigated to analyse the quantitative distribution of carbonate facies and carbonate‐producing organisms.

Organic geochemistry of Paleogene Pabdeh Formation in northern Dezful embayment, Zagros, SW Iran

open access: yesBoletín de la Sociedad Geológica Mexicana, 2022
In this paper, the organic geochemistry of Upper Eocene-Oligocene Pabdeh Formation, in northern Dezful Embayment, SW Iran, was studied using combination of geochemical measurements including Rock-Eval pyrolysis, Gas Chromatography and Gas Chromatography-Mass Spectrometry. A total of 14 shale samples of Pabdeh Formation were obtained from 14 wells in 11

Eocene to Oligocene nannofossils stratigraphy and environmental conditions in Izeh Province, Zagros Basin, East Tethys

open access: yesJournal of Palaeogeography, 2021
Data obtained from the calcareous nannofossils, distributed in the upper part of the Pabdeh Formation (Priabonian–Rupelian) and the lower part of the Asmari Formation (Chattian) in the Bid-Zard section, were used to investigate the Eocene to Oligocene ...

Biostratigraphic Study of the Gurpi Formation Based on Planktonic Foraminifera In Lar Area (Kuh-e-kurdeh Section) [PDF]

open access: yes, 2009
The study of planktonic foraminifera of the Gurpi formations at Lar area (Kuh-e-kurdeh section) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Five biozones were determined.

Constraint on foreland basin migration in the Zagros mountain belt using Sr isotope stratigraphy [PDF]

open access: yes, 2015
We have constrained the time-space migration of the Zagros foredeep basin by performing Sr isotope stratigraphy on 31 samples of marine macrofossils from Neogene sediments now exposed in the Zagros mountain belt in southwest Iran.
