Investigation of Organic Matters and their Roles in Deposition and Phosphate Mineralization in the Kuh-e-Sefid Deposit, Ramhormoz

Journal of Economic Geology, 2017
Introduction It has been recently stated that phosphorite deposits are in fact marine biogenic materials, due to bacterial activity producing bio-apatite. In addition, Phosphorites contain 15–20 wt.% P2O5 (Tzifas et al., 2014).

A Numerical Modeling Study for Determining the Optimal Depth of Grout Curtain in Foundation and Abutments of Karun 4 Dam [PDF]

Analytical and Numerical Methods in Mining Engineering, 2017
Some experimental relations have been developed for determining the grout curtain depth, but these relations cannot be applied to any dam with any geological condition.

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

Environmental 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 ...

Chemical Variation during Pabdeh Formation Deposition, Zagros Basin: Gurpi-Pabdeh-Asmari Boundaries determination and Paleoenvironmental Condition [PDF]

Journal of Geology & Geosciences, 2012
Determination of the formation of the Pabdeh boundary is a main challenge in Zagros sedimentary basin area. The work on hand is an attempt to clarify those based on chemical changes. The location under observation is the outcrop of the Pabdeh Formation (Paleocene-Oligocene) in Bangestan Anticline, the southern part of Zagros orogenic belt.

Audio‐Magnetotelluric Survey for Groundwater Investigation in the Al‐Jaww Plain in Eastern Abu Dhabi, Al‐Ain, United Arab Emirates

Earth and Space Science, Volume 10, Issue 12, December 2023., 2023
Abstract The United Arab Emirates (UAE), located in an arid climate zone with low rainfall, relies on shallow aquifers for freshwater. Understanding the depth and extent of such aquifers is crucial for meeting water supply needs. The UAE's hydrogeology is influenced by neighboring mountains in Oman.

Subsidence and Uplift History of the UAE and the Western Flank of the UAE‐Oman Mountain Range

Tectonics, Volume 42, Issue 10, October 2023., 2023
Abstract The western flank of the UAE‐Oman mountain range offers a unique geodynamic setting to study the development of a cratonic rift into a mature passive margin and its subsequent flexure under orogenic load. However, the geodynamic processes driving this evolution are not fully understood. In this study, seismic and biostratigraphic data from 283

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

Earth 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.

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

The 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.
