This study explores the third stage of the Tigris River terraces at the University of Mosul. Due to its importance, most of its buildings, especially the modern ones, were built on these terraces, and some engineering problems appeared in those buildings. The current study aims to know the petrography of the rocks, the emergence of these terraces,...

The study area is located structurally southwest Makhulplunge. Quaternary deposits overlying unconformably Fat'ha and Injanah Formations. The Quaternary deposits beneath Sallahuddin oil refinery display topsoil and the third stage of Tigris river terraces. The latter is represented by braided to meandering river channels composed of; conglomerates,...

The scarcity of clay and alluvial deposits in the valley of the Tigris River and its tributaries in the northern region of Iraq called for the search for suitable clays for the construction ceramic industry in geological formations. A geological survey of the mudstone layers of the Al-Fat’ha and Injana formation rocks was conducted in the districts...

The last four decades weather forecasting data marks the precipitation declination and increase dry years, in addition to the desertification migration on the west and northwestern Mosul city. This led to studying the Al-Shor Wadi area to try to make use of the karstic spring water flow through it and to harvest the rainfall flow water. These need...

Two types of unconfined aquifers had been recorded within the eastern bank of the Tigris river in Mosul city. These aquifers are present within the flood plain of the river and; Injanah Formation and ancient Tigris river terraces respectively. Slight and short fluctuation in water table level occurred within the first type of aquifers, and general...

Two main areas were chosen to investigate the water quality of Nwaiget spring and hand dug well at Tebba Riyah village. Nwaiget spring is located near the core of Butmah west anticline, it locates stratigraphically within Unit (A1) of the lower member of Fat'ha Formation. Tebba Riayh hand dug well is located in the synclinal area north the Butmah w...

Usually phosphate industry disposed phosphogypsum, as a waste, while in Al-Qaim phosphate industry there is another one which is alkaline waste call (slime), most of it is lime may reach up to 80% CaO), and other ratios of P2O5and Al2O3 may reach up to 15% and 10% respectively, the later makes the phase of the slime jelly having the ability to hold...

To understand the sources of water quality variations of both Abu-Maria spring and Al-Saja'a sinkhole which are located geologically within Afgani anticline, about 55 km. northwest Mosul city, it is important to study the geological and geomorphological nature of the anticline and its associated karstification phenomena. The study revealed that bot...

The Jurassic succession of western Iraq includes the Ubaid, Hussainiyat, Amij, Muhaiwir, and Najmah formations. Each formation is composed of basal clastic unit overlain by upper carbonate unit. Extensive and huge erosional unconformity occurred at the Triassic–Jurassic boundary due to marked shifting of structural (E–W) strike of the Triassic (Rha...

Hardsetting soil is recorded for the first time in Iraq within a claystone bed about 2 meter thick, which is developed mostly as alluvium deposits. A dry medium tough claystone bed collapses, fragmented, and becomes powder within few seconds upon wetting with hearable structural fragmentation. Preliminary mineralogical, chemical and morphological i...

The study aims to evaluate the geological condition beneath concentrated H 2 SO 4 production plant (Unit 200), after the sever destruction in 1991 due to the American shelling. The military operation causes flushing and seeping of the H 2 SO 4 to the underlying soil profile and bedrocks. Consequently, this led to the alteration of the mudrocks, and...

During 1990s, electricity power generation crises had reached its maximum level in Iraq. The government focused on supplying Baghdad by the available power on expense of other governorates. Mosul governorate, for example, suffered 20h/day of electricity shut down. This situation forced people to rely on diesel generators to tackle this problem. Acc...

Several factors contribute to the developing of the ground water problem in the state company for phosphate at Al- Qaim area, Iraq. The most important factor was the bombardment of the sulphuric acid tanks and their pipes in (1991) during the Gulf war. This resulted in the flushing and seeping of concentrated sulphuric acid, mixed with surface wate...

The two Formations Ga’ara and the lower clastic unit of Hussainiyat were deposited in fluvial system of deposition with slight different behaviors like the thickness of fining upward cycles in different times, in addition to, some stratigraphic, structural, paleogeographic and geochemical evidences. The present work aimed to compare between these...

Petrographical and geochemical studies were conducted for phosphorite of Akashat mine which belongs to Hirri unit (Middle Paleocene) within AkashatFormation. It is used in phosphate fertilizer industry after its transportation to Al-Qaim. Additionally, the study investigates in the acidic and basic by-product solid waste (phosphogypsum and slime) r...

The phosphate fertilizer production in AL-Qaim depends primarily on concentrating the phosphates from 21% P 2 O 5 to about 30% during burning and wet sieving processes. Carbonate fluorapatite (Francolite) is the only phosphatic mineral in these rocks persists as pellets, oolites and bone fragments associated with calcite presents as the main minera...

During the course of an investigation to evaluate the area for mapping distribution of deposits , different proposed hydraulic structures and construct ion materials.Terraces within the Valley of the River Tigris were mapped at three locations in northern Iraq. Four stages, ranging in age from pleistocene to Recent have been recognized. The paper r...
