“…In the Late Miocene at the studied area, the basin became relatively shallower and coastal. The Euphrates Formation beginning deposited as clastic and calcareous, consisting of fossiliferous oolitic and dolomitic limestone, with a layer of green marls on top (Al-Ghreri et al, 2013). During the Middle Miocene, the basin was growing similar to the Lower Miocene subcycle as shallow water.…”

Portland Cement is manufactured by adding 3% gypsum to clinker which is produced by grinding, pulverizing, mixing, and then burning a raw mix of silica, and calcium carbonate. Limestone is the main source of carbonates, while clay collected from arable land is the main source of silica. The marl in the Euphrates Formation was studied as an alternative to arable lands. Nine boreholes drilled and penetrated the marl layer in selected locations at the Kufa cement quarry. Forty-one samples of marl from boreholes and four samples of limestone from the closed area were collected. The chemical content of the major oxides and the hardness of the marl layer was very encouraging as a raw material for Portland Cement as they are SiO2 (17.60), CaO (37.89), MgO (1.94), Fe2O3 (2.47), Al2O3 (4.21), K2O (0.731), SO3 (0.35), and Na2O (0.062). The marl was used in designing a raw material mix suitable for rotary kiln feed and produced a clinker conforming to the approved specifications. The designing a raw mix consisting of 80.30% of marl with 19.70% of limestone. The investment of the marl layer can be used as an ideal alternative to the arable clay giving fit quality to the international specifications, reducing production costs during quarry operations, reducing the energy consumption and equipment wearing.

“…Recently [7] suggested another section at Al-Baghdadi area as a reference section, because the type section at wadi Fuhaimi submerged by the Al-Qaddisiyah lack. Ever since, many studies appeared for different aim, including those of; [8]; [9]; [10]; [4]; [11]; [12]; [13]; and off course, [7], [14] detailed all these studies.…”

The Euphrates Formation (Lower-early middle Miocene) shallow water carbonates, western Iraq was studied in order to determine its microfacies and depositional environment. According to the benthic foraminiferal assemblage along with other skeletal and non-skeletal components, Fourteen microfacies associations types (F1-F14) are recorded and distributed as: Lime mudstone, miliolids wackestone, alveolinids wackestone, echinoids wackestone, bioclastic packstone, peliods packstone, miliolids packstone, peneroplids packstone, rotaliids packstone, miliolids grainstone, peliods grainstone, ooids grainstone, miliolids-peneroplids grainstone, and peneroplids grainstone that were deposited in three facies belts, restricted marine, shoal, and open marine environments. Based on field observations, microfacies analysis and sequence stratigraphic concepts, the Lower Miocene successions is represented by four order cycles (A, B, C and D) they are mostly asymmetrical showing slightly lateral variation in thickness and symmetry. These cycles represent a succession episode of sea level rises and stillstands. The nature of these cycles reflects variation in the relative sea level resulted from eustatic and tectonic subsidence. Cycle A is underlain by Anah Formation, while cycle C is overlain by SB1 Fatha Formation. According to sequence development, the study area shows low rate of subsidence and the major controlling factor that effect is eustatic sea level fluctuation.

“…The Early Miocene units have been studied by numerous authors in many parts of Iraq, including the central and western areas (Abawi and Hani 2005;Al-MutwaIi and Al-Banna 2005;Al-Youzbaki et al 2005;Al-Juboury et al 2007;Aghwan and Abdulrahman 2009;Al-Ghreri et al 2010;Al-Juboury et al 2010;Al-Ameri et al 2011;Al-Dabbas et al 2013;Al-Ghreri et al 2013). However, the Early Miocene shoreline was not previously defined in the Kurdistan Region of Iraq.…”

A sedimentological investigation of the Early Miocene deposits at the periphery of the Zagros Foreland Basin, Kurdistan Region, around Qishlagh-Sargrma and Darbandikhan, reveals the presence of the Euphrates and Jeribe Formations in this area. A carbonate-dominated unit, comprising four regressive carbonate cycles, at the base of the Fatha Formation, has been investigated to characterize the depositional environments and stratigraphic context of these Early Miocene deposits. Outcrop and thin-section analyses of the carbonate succession reveal a gently inclined, carbonate-dominated ramp based on the depositional lithofacies and microfacies. Eight carbonate microfacies were identified and interpreted to have been deposited in a shallow marine environment. The Euphrates Formation passes up from deposits of restricted lagoon to shoal depositional environments, while the Jeribe Formation was deposited in a hypersaline lagoon to a restricted lagoon. The Early Miocene index fossil Borelis melo melo was identified in the deposits of the Euphrates Formation. Stratigraphic correlation of the studied sections allows the development of a revised palaeogeography for the Early Miocene deposits in the Kurdistan Region.
