Geoengineering Evaluation of Dammam Formation Rocks-Bahr Al-Najaf Depression-Middle of Iraq
The Dammam Formation, 250-meter-thick geological formation in the Bahr Al-Najaf Depression that is part of the Salman Platform, comprises re-crystallized limestone mixed with nummulite near the base. It was deposited in a shallow marine environment and extends from Al-Qaim to Samawa along t...

| description | The Dammam Formation, 250-meter-thick geological formation in the Bahr Al-Najaf Depression that is part of the Salman Platform, comprises re-crystallized limestone mixed with nummulite near the base. It was deposited in a shallow marine environment and extends from Al-Qaim to Samawa along the Euphrates River. The formation is part of the secondary Salman Zone of the main outstanding Stable Shelf. The engineering evaluation of the Dammam Formation in Bahr Al-Najaf depression was determined by ten samples which were chosen to represent the study area. The study includes both field and laboratory components. On the field side, data on the study region and samples were obtained. Physical, engineering, chemical, and mineralogy tests were carried out in laboratories. The total density ranges from 1.848 to 2.664 gm/cm3, the porosity value ranges from 5–20 %, while the water absorption of limestone rocks values 1-7.7 %. Engineering tests were performed, including uniaxial compressive strength, which ranges between 59 and 177 Mpa. The rocks of the Dammam Formation are suitable for the manufacture of Portland cement according to global standards, as supported by chemical analysis. |
