Study Objectives and Findings
​The study aimed to investigate the geological, geochemical, and petrographic characteristics of iron deposits, as well as to determine the origin, formation processes, and economic potential within the study area.
​Key Findings:
​The iron deposits in the study area are classified as Banded Iron Formations (BIF) of marine chemical origin.
​They were formed from hydrothermal ore solutions in a reducing marine environment.
​Deposition occurred through mixing with oxygenated seawater, leading to the precipitation of iron ore in a medium-depth marine environment associated with volcanic rocks formed within active tectonic oceanic island arcs.
​The characteristics of these deposits align with Precambrian BIFs found globally, specifically within the Arabian-Nubian Shield (e.g., deposits in Egypt and Saudi Arabia).
​Recommendations
​The researcher proposed several critical recommendations for future development, including:
​Conducting advanced geological studies using drilling and subsurface exploration.
​Utilizing remote sensing technologies to determine the depth and extent of iron formation layers buried under sand dunes.
​Attracting specialists and investors to initiate exploration projects aimed at the economic exploitation of these resources.
​Conclusion and Result
​Upon thorough examination, the defense committee recommended the acceptance of the thesis. The candidate was awarded a Master’s Degree in Economic Geology with a general grade of 85% (Very Good).
