Summary: This study examines the active tectonics along the Bamo anticline through quantitative analyses of geomorphic indices. The results indicate that the region exhibits high to moderate tectonic activity, with 38% and 56% of the area classified as high and moderate activity, respectively, and 6% classified as low activity.

Summary: This study focuses on the Chia Gara Formation in Northern Iraq, which is considered a major source rock for the Kirkuk oil field. The formation consists of bituminous limestones and calcareous shales deposited during the Late Jurassic - Early Cretaceous. The study reveals that the formation was deposited in a shallow marine environment, with significant terrestrial input. The results provide insights into the organic matter characteristics and maturation of this prolific Formation.

Summary: This study investigated the geogenic sources of arsenic and fluoride in groundwater in the Kurdistan Region of Iraq using the hydrogeochemical method. The analysis showed that arsenic concentrations ranged from 0.19 to 7.8 micrograms per liter, while fluoride concentrations ranged from 0.01 to 2.1 milligrams per liter. The concentrations of arsenic and fluoride were related to their geogenic sources and aquifer conditions. Some samples also indicated the presence of contamination sources. The study found that while arsenic levels were within WHO guidelines, some samples showed a higher concentration of fluoride, indicating a serious risk of fluorosis in certain areas.

Summary: This study presents a clear case of seismic activity caused by the Quaternary reactivation of a seismogenic blind basement fault. The findings suggest that earthquakes in the Sheladiz area are mainly produced by left-lateral strike-slip movements along a seismically active basement fault. The stress inversion results indicate a predominant N-S oriented maximum compressive stress in the area, supporting active deformation rates along the Arabia-Eurasia collision zone.

Summary: This study provides a detailed investigation of the tectono-stratigraphy, regional structure, and mesoscopic fractures in the Duhok region of the Zagros fold-thrust belt in Northern Iraq. It examines key structures through field studies, remote sensing-GIS analyses, and cross-section restorations. The study reveals the characteristics of the Duhok fold belt and its two main detachment levels, as well as the deformation processes that have occurred in the region over time.

Summary: The study in the NW Zagros region of Kurdistan, Iraq, reveals the basin dynamics and tectonic controls of the foreland wedge-top units and intermontane units, as well as the shift in sediment provenance from west to east in response to ophiolite obduction and continental collision. The detrital zircon provenance data suggest a decrease in magmatism around 36 Ma and a connection of drainages with the Neogene foreland basin following the incipient Arabia-Eurasia continental collision during the latest Eocene.

Summary: This study investigated the microfacies analysis and depositional environment of the Jeribe Formation in the northwestern part of Kurdistan region-northern Iraq. Field observations and petrographic analysis of thin sections revealed the presence of various shallow marine derivative fossils and different microfacies types. Based on environmental differentiation, two facies associations were identified: intertidal and lagoon. The Jeribe Formation was found to have been deposited in a shallow marine environment, transitioning from an intertidal setting to a semi-restricted lagoonal environment.

Summary: The study focused on the Sarvak Formation in the Zagros Basin of Iran, specifically at the Pyun Anticline section. A rich fossil assemblage and five biozones were identified, while 13 carbonate microfacies were also recognized based on petrographic and sedimentological analyses. The microfacies confirmed a ramp-type paleoenvironment.

Summary: This study focuses on the geological characteristics of the Sarab structure in southwestern Iran and its major exploration target, the Asmari Formation, using the magnetotelluric method for detection and analysis. The results indicate that the electrical contrasts of sedimentary rock layers have a significant impact on exploration, and highlight the resistive structure characteristics of the Sarab Anticline in the region.

Summary: This article reports the discovery of gossanite-type hematite and magnetite ore associated with sulfide mineralization in the Rayat area of NE Iraq. Detailed petrographic, mineralogical, and geochemical data define the features of the gossanite and the associated sulfide-rich rocks, providing an assessment of the mineralization and its relation to hydrothermal, microbial and alteration processes. The potential economic significance of the ore body in addition to Fe is the silver-nickel (Ag-Ni) and cobalt (Co) mineralization, highlighting NE Iraq as a potential mineral-rich domain.

Summary: The study of the origin and evolution of diagenetic fluids in Upper Jurassic carbonate rocks along the Zagros thrust-fold Belt revealed two major diagenetic stages involving a mix of seawater and freshwater in the initial stage, and a blend of meteoric water and hot fluids in the second stage. The high resolution analysis involved in-situ strontium isotope ratios, stable isotopes, petrography, and fieldwork to provide a comprehensive understanding of the diagenetic processes.

Summary: The ongoing shortening between the Eurasian and Arabian plates is primarily accommodated within the Zagros Fold-Thrust Belt, but the distribution of active shortening within the belt, particularly in its NW part, is not well constrained. Depositional ages of uplifted river terraces and kinematic modeling were used to calculate long-term slip rates during the Late Pleistocene to Holocene, providing insights into faulting and folding rates in the area. Different slip rates were observed in various faults and folds, with distinct deformation patterns both in the NW and NE parts of the Zagros belt.

Summary: A sedimentological investigation in the Kurdistan Region of NE Iraq revealed a cyclical facies arrangement of carbonate-evaporite ramp facies, with each cycle showing a shallowing-upward trend from lower-energy to higher-energy facies. The environments included various lagoons and coastal settings, with an increase in siliciclastic supply and decrease in carbonate and evaporite production towards the top of the succession. Progradation and shoreline migration caused lateral and vertical facies changes over time.

Summary: The Upper Triassic Baluti Formation in the Kurdistan Region of northern Iraq has been identified and evaluated for its source rock potential based on log response in selected wells. The formation consists of thinly interbedded shales, carbonates and anhydrite, with low to moderate total organic carbon (TOC) content. However, the presence of solid bitumen and the relatively low T-max values suggest limited organic matter preservation and migration. Further analysis is needed to fully assess the formation's hydrocarbon potential.
