  • The Impact of Limestone Quarry on Bashiqa Mountain, Nineveh Governorate, Iraq
    Batool Al-Juboori, Azealdeen Al-Jawadi, Mohammed Al-Abbasi
    Iraqi National Journal of Earth Science, 2025
    The primary goal of this study is to investigate how limestone quarries affect the natural environment in Bashiqa area, Nineveh Governorate, northern Iraq. The research initially employs a long-term satellite image surveillance to track changes in the area and the growth of quarrying operations. Furthermore, fieldwork is done to ascertain the geotechnical characteristics of the rocks, and sample collection is carried out for laboratory analysis to determine the engineering qualities of the rocks and whether they are worthy of the environmental changes that have taken place in the region. Every geotechnical characteristic is measured in the field including the degree of openness, surface roughness, discontinuity spacing, and rock hardness estimate. The petrophysical characteristics, compressive strength, and slake durability are measured in the laboratory. From an engineering perspective, it is discovered that these rocks are appropriate for construction; however, weathering processes rapidly alter the majority of them. The physical and mechanical characteristics of the extracted stones varied; thus, quarry owners need to identify the different types of rocks and how best to use each type to minimize their influence on the environment.

    Iraqi National Journal of Earth Science, 2025
    Military efforts to evict terrorist organizations from the governorate caused a widespread destruction in Mosul, particularly on the right side of the Tigris River. The city required a complete reconstruction of its buildings and infrastructure. Geotechnical investigations were carried out in the majority of the right-side areas in preparation for the sewerage projects. 64 boreholes were drilled to a depth of 5 m. During the drilling, the physical and engineering properties investigations of soil have been studied, and the vertical soil depths are divided into three beds (1.5, 3, and 5 m). The investigation was done by Al-Mawarid Bureau for geological and engineering geology investigations. The data are interpolated by spatial analysis tools in the ArcGIS application using the Ordinary Kriging Method (OK), which is the better method to represent distribution values nearest to the actual values compared with other methods of interpolation. The results appear that the soil was distributed into three groups: high plasticity clay, low plasticity clay, and low plasticity silt. Most areas have a liquid limit between (30-50%), a decreased plasticity index toward deeper layers, and low clay activity, while the swelling potential is high except in the southeastern part of the study area, where the bearing capacity increases with the depth. In the northeast, the foundation type is compact footing with 1.8 m depth, and in the southwest, it needs a deep pile with 5 m depth. While the chemical test of the soil in study area has an intensive sulfate environment and the chloride content is between (0.03-0.04) %.
  • The Quantification of the Geological Strength Index (GSI): A Review
    Azealdeen Al-Jawadi, Fahmy Mohammed, Iman Jaafar, Colin T. Davie
    Iraqi National Journal of Earth Science, 2025
    The first Geological Strength Index (GSI) Chart was invented to classify rock mass properties. The GSI Chart developer assumes that qualified and skilled geologists or engineering geologists would evaluate and record the rock mass properties. Without a robust geological background and field experience, many researchers misuse the GSI charts. Due to the abnormal increase in GSI charts used in the recent decade, the update was necessary to eliminate visualization and assumption problems in GSI charts. The correlation between the quantified GSI charts was fair to reduce the uncertainty in estimating the rock strength properties. Many GSI charts were developed or updated to be quantified rather than visualized charts, which have become more specific and universal. The GSI Chart was modified by including additional parameters such as joint condition, rock quality designation RQD, volumetric joint count (Jv), and block volume (Vb). The modified GSI charts facilitate more practical use and reduce error. However, field observation and visualization are still essential for rock strength property estimation, particularly in the geomechanical classification of the rock mass. Some modifications add too much complexity to the original chart by adding a specific parameter or modifying it, making the decision-making based on the GSI Chart more difficult to find rock strength parameters. In some cases, a rock sample gets a significantly different GSI value for the same outcrop rock. Mixing 3D numerical modeling tools such as synthetic rock mass (SRM) or three-dimensional numerical modeling (3DEC) with GSI values is the most convenient method for estimating joints' strength and assisting engineering geologists in overcoming these obstacles.
  • Tracking Shaft Integrity of Jet Grouting Piles Injected in Soft Soil Layers Based on Sonic Integrity Test Method: A Case Study from Erdemli, Mersin Region, South Turkey
    Ahmed Mohamed, Nihad Aljuboori, Azealdeen Al-Jawadi
    Iraqi Geological Journal, 2024
    Many studies have focused on using the non-destructive testing (NDT) method to determine defects in piles. This paper presents an analytical approach that compares the obtained profiles with typical profiles to confirm the integrity of jet grouting column piles using the cast-in-situ Sonic Integrity Testing (SIT) method. In this context, grouting piles are being constructed within the scope of the under-foundation in Erdemli/Mersin Province, Turkey. SIT testing was performed on jet grouting piles by performing integrity tests on piles manufactured, which varied in length according to the field geology and the thickness of the soil layer. These pile tests are performed to determine changes that may occur in the pile's cross-section for various reasons. In the present study (in 2024) SIT was carried out on a total of 148 jet grout piles. In the SIT performed on the piles, at least six records were taken for each pile, the records were examined, and the evaluations and results were given graphically. The cross-sectional alterations and fractures that can be found in the pile cross-section as well as the subsurface soil condition are the outcomes of the integrity tests, and they have an immediate impact on carrying capacity. Based on the acquired data and comparisons with reference profiles, the 148 piles that were produced and examined at the site exhibit no discontinuities or flaws and are structurally intact. By utilizing this method, the necessity for costly on-site soil replacement or foundation handling will be avoided or prevented.
  • Classification, Hazard Assessment, and Optimization Strategy for Some Critical Rockfall Locations in the Duhok Area, North of Iraq

    Iraqi Geological Journal, 2024
    Duhok City is characterized by being built in a mountainous area, mostly limited between the Zawa and Bekhir mountains. The city and surroundings have been exposed to many rockslide accidents, especially during the rainy seasons. Some rock slides and falls occurred as a result of earthquakes occurring nearby in Iraq and Turkey. The current study aims to classify and evaluate the risks of landslides, to deal with them, and strategies for improving hazardous sites that may be subject to sliding. Many road cuts have been noticed at different locations in the Duhok vicinity and they were in critical equilibrium. The locations of the road cuts are detected within four major anticlines which are from south to north, Bekhair, Brifka, Chia Gara, and Kham Teer anticlines and they are arranged in echelon patterns extending from east to west, following the Taurus Mountain chains from Turkey. The main rock units seen in these locations consist of limestone, marly limestone, chalky limestone, and dolomitic limestone. Different types of structurally and non-structurally controlled failures have been identified, however, since the study is restricted to carbonate rocks, the structurally controlled failures are most important in this research due to their competence. Three types of slopes have been classified from the field observations, planar, wedge, and toppling failures. During the year 2024, and because of the heavy rain season and earthquake activities, many of these slopes were triggered. Many rockfall accidents have been registered alongside some narrow roads and highways in the city and surroundings.

    Iop Conference Series Earth and Environmental Science, 2024
    The local and central governments focused on the right side of Mosul for urban development, especially after the destruction that occurred during its liberation. The view of the study area on the river and the green spaces on the other side of the river drew the attention of the Municipality of Mosul to develop it into a tourist attraction that reflects the cultural aspect of this ancient city. 26 exploratory boreholes were drilled in the study area, with depths ranging from 10 to 20 meters, and their geotechnical specifications were determined. In this study, the Pearson correlation coefficient was used to identify the parameters that have the greatest influence on the geotechnical specifications of the layers and to classify the engineering classes. Interpolation was used in Arc GIS to compare the distribution of geotechnical properties in the three layers at depths of (3, 6, and 9 m) and to calculate the average values of geotechnical properties from a depth of (1.5 - 9 m). The specifications were classified into five classes using a classification of the different characteristics. Geotechnical maps of the study area were created to show the distribution of engineering properties and their classification into isotropic zones, allowing each application zone to be provided with the appropriate building type. The results revealed that the northwestern part of the area is best suited for towering structures, while the rest of the neighborhoods were considered less suitable.

    Iraqi National Journal of Earth Science, 2024
    The purpose of this study is the find a method of treatment to improve the properties of claystone of the geological formations that are widespread in Northern Iraq by kaolinite addition. Washing clay with different ratios of water is another treatment to find the perfect quantity of water to dissolve the more percent of salts. More improvement was found by adding 10% of kaolinite and the sample was classified as grade A according to Iraqis’ specifications number 24 in 1988. The water absorption of the treated sample is 16.5%, the compressive strength is 34.9 MPa. and low efflorescence. the sample characteristics are good when adding 5% kaolinite, the water absorption of 19.5%, compressive strength of 30 MPa. and low efflorescence. While The non-treated sample has a 22.2% of water absorption, 20.6 MPa of compressive strength, and medium efflorescence. The treatment by water dissolution is good in some manner, where dissolution increased to 3.2% when the water quantity increased to double of sample weight, and it increased to 4.8% when the water quantity increased five-fold. Eventually, the studied rock beds have well characteristics, very large reserves, and adequate to operate eight factories of 50.000 brick/day for 50 years and it has 7.478.258 m3 of clay.

    Iraqi Geological Journal, 2023
    A geological field survey was conducted in Soran District in the Beeston cave located in the Bradost Anticline, northeastern Iraq. The presence of an upper hole in the ceiling of the cave with a diameter of about 3 meters and a main gap dimension is up to 40 x 22 m was found through that. ‎ In combination with an analysis of the remote sensing data, a detailed geological survey of the caves with the surrounding areas and an engineering survey were carried out. The geological survey included the stratigraphic sequence of the area between the lowest and highest levels in the study area. It also contains setting and geotechnical parameters for bedding planes and discontinuities. The engineering survey included the measurement of cave dimensions, the distribution of stalactites and stalagmites, and the height of weathering terraces. ‎‎An analysis of engineering and geological data estimated the approximate timespan of cave formation, and the scenario for cave formation was prepared by adding remote sensing data that could be used in the future to determine other areas where such a cave could be formed. The study reveals the scenario of the cave formation, estimates the age of the cave, and the formation timespan of the cave creation.
