“…A homogeneous sedimentary rock that is predominately composed of microscopic radiolarian organisms (Figure 5c). This fragment is derived from radiolarian chert beds and which are considered as a weathering product of the Cretaceous Qulqula Radiolarites series, NE Iraq that is adjacent to the Sanandaj-Sirjan Zone of Iran (Al-Juboury et al, 2009).…”

The quaternary sediments have been studied in four sections; Garmian area, Kurdistan Region, North East Iraq, which are multi-features, multi-sources, and variable lithological compositional characteristics. The grain size granulometry was used and identified, gravel, sand and mud. Gravel-sized particles are partially producing a greater amount than sand and mud size in both sections (Sar-Qallah-1 and Salih-Agha). Statistical parameters such as (mean, mode, sorting, skewness and kurtosis), have shown that the sediments are very poorly sorted, very fine skewed and platykurtic. Petrographic studies of sediments under polarized microscope investigated that these sediments are predominately consisting of (chert and carbonate rock fragments), with the existence of few amounts of igneous and metamorphic rock fragments, feldspar and monocrystalline quartz. These fragments types are an indication of multiple source rocks originate from Ophiolites and thrust sheets from the Penjween area (North Iraq). Various types of heavy minerals are identified; opaque (hematite and pyrite), and nonopaque minerals (pyroxene, amphibole, epidote and zircon). X-ray diffraction technique is used to interpret clay mineralogy which indicates that chlorite and palygorskite are the main clay mineral with the presence of non-clay minerals such as quartz and calcite.

“…Determination of tectonic location is influenced by factors such as sedimentation, diagenesis and initial composition of sediment (Pettijohn et al, 1987;Bhatia, 1983;Chamley, 1990). Therefore, the main elements of the sand can be used to determine their tectonic position (Bhatia, 1983;Von Eynatten, 2003;Armstrong-Altrin &Verma 2005;Al-Juboury et al, 2009;Sahraeyan & Bahrami, 2012 As shown in Fig. 7, based on changes in the values of the main elements, the cranial rocks of oceanic arch islands,, continental arch islands, active continental margin, and passive margin can be separated from each other.…”

The location of the Fenced Lagoon in the urban basin of Bandar Anzali, which should be considered due to its impact on the lives of the people of the region in terms of the conservation of the wetland and its environmental issues, and, on the other hand, the potential of this area to be introduced as a geotourism center determine the need to investigate the area’s sedimentology and geochemistry. Therefore, to study sedimentary and geochemical properties of the Fenced Lagoon sediments located in Bandar Anzali, 33 samples were taken in the form of 6 cores and 12 grabs, and basic sedimentation tests and heavy metals measurement were carried out on them .Studies show that the sediments range from sand to clay in terms of gradation and have mainly coastal-river origin. The sediments of this lake are classified into four sedimentary types: Muddy Sand, Slightly Gravelly Muddy Sand, Sand and Slightly Gravelly Sand, and sand is the main component of all of these sediments. The most abundant sedimentary types belong to Muddy Sand and Sand and the least abundant sedimentary types belong to Slightly Gravelly Muddy Sand and Slightly Gravely Sand. The nature of the source rock is derived from acidic to intermediate combination and in general, sedimentary rocks of the area under study are within the continental arch islands and, to a lesser extent, the active continental margin.

Therefore, to study sedimentary and geochemical properties of the Fenced Lagoon sediments located in Bandar Anzali, 33 samples were taken in the form of 6 cores and 12 grabs, andbasic sedimentation tests and heavy metals measurement were carried out through XRF. Studies show that the sediments are ranged from sand to clay in terms of gradation and have mainly costal-river origin. The sediments of this lake are classified into four sedimentary types: Muddy Sand, Slightly Gravely Muddy Sand, Sand and Slightly Gravely Sand and sand is the main component of all of these sediments. The most abundant sedimentary types belong to Muddy Sand and Sand and the least abundant sedimentary types belong to Slightly Gravely Muddy Sand and Slightly Gravely Sand.
