The Pila Spi Formation is exposed in Permam Mountain forming its carapace, and continuous ridges for few hundreds of kilometers. The rocks of the formation are mainly dolomitic limestone, dolomite, and limestone with various proportions. The thickness of the formation in Permam Mountain is about 100 m. Nine samples are collected from the Pila Spi Formation along a recently road cut across Permam Mountain. The sampling interval varies from 10 to 15 m. The collected samples were subjected to X-ray fluorescence (XRF) spectroscopy test to indicate the percentages of the main oxides in the samples. The results showed that the chemical composition of samples No. 1 and 9 meet the Iraqi standards for cement industry, whereas the remaining samples (Nos. 2–8) do not meet the Iraqi standards, and their total thickness is 80 m. To evaluate the suitability of the exposed rocks for cement industry in the sampled section within the Pila Spi Formation, different ratios of sample No. 1 were mixed with different ratios of a sample called sample No. A, it represents a mixture of samples No. 2–8. The mixing ratios are: (Sample No. 1/sample No. A) 50/50, 60/40, 70/30, 80/20, and 90/10. The same procedure was repeated for Sample No. 9. Another attempt was performed by mixing equal ratios of samples Nos. 1 and 9 with the same performed ratios with sample No. A.The chemical compositions of the samples were indicated using XRF test. The results showed that the best mixing ratios for the cement industry are 90:10, 80:20, and 70: 30 (samples Nos. 1+9: sample No. A).

The Pila Spi Formation is one of the prominent formations forming continuous ridges in Kurdistan Region. The thickness of the formation ranges from 15 to 110 m, consisting of well-bedded limestone, dolomite, dolomitic limestone, and very rare marl beds. The study area is located about 15 km east of Koya town, next to the abandoned tunnel through a deeply cut valley which has exposed 50 m of the formation. However, the uppermost part of the exposed section may belong to one of the Oligocene formations of Kirkuk Group. The study area was selected within the Pila Spi Formation because the rocks of the same formation and along the same ridge, about 45 km west of the study area showed encouraging results for cement industry. The average CaO is about 51%, whereas the average MgO is 1.8%. Therefore, eight samples were collected at constant thickness from the exposed section. The samples were subjected to X-ray fluorescence (XRF) test to indicate the main oxides in the sampled section. The acquired results from the XRF tests showed that the chemical composition of the exposed rocks within the Pila Spi Formation is suitable for cement industry, also for paper and paint but needs some treatment. Accordingly, another eight samples were collected from the same section to increase the density of sampling, totaling to 16 samples.

The main lithological composition of different formations in the Iraqi Kurdistan Region is the carbonate rocks; some of those rocks are suitable for cement production; such as Qamchuqa Bekhme, Sinjar, Pila Spi and Anah formations. However, the six existing cement plants in are using limestone beds, five of those plants are using limestone from the Sinjar Formation, and one plant is using limestone from the Anah Formation. Recently, performed research works confirmed that the limestone beds within the Qamchuqa, Bekhme and Pila Spi formations are very suitable for cement production. The current research work deals with studying the exposed limestone beds within the Bekhme Formation at Hareer Mountain in the central part of IKR to check their suitability for the cement industry. Accordingly, we collected 12 rock samples from a section within the Bekhme Formation at an almost constant sampling interval (5 m); however, for two samples the sampling interval was 6 and 8 m (sample No. 2 and 12, respectively). Each sample represents a channel sample for the concerned sampling interval to be representative for the thickness of the sampled interval. The total thickness of the sampled section is 64 m with a covered interval of 30 m, totaling up to 94 m. The collected 12 samples were prepared at the laboratory of the University of Kurdistan Hewler and were subjected to XRF test at Mass Cement Plant (Sulaimaniyah) to check the concentration of certain oxides that are used in the Iraqi Standard for cement production. The acquired concentrations of the main oxides (CaO, MgO, Al2O3, Fe2O3, Na2O, K2O, SO3), and Cl and L.O.I. at each sample were changed to weighted averages and the results were compared with the Iraqi standards for cement industry. The result was the sampled rocks are excellent for cement production.

Covered Area

A stream survey was conducted in the Sidakan vicinity in the northeastern part of the Iraqi Kurdistan Region, which covered the catchment area of the main stream. The covered area is about 450 km2. The exposed rocks in the study area are mainly igneous with subordinate sedimentary and metamorphic rocks. The catchment area was divided into 14 sub-basins using Global Mapper software. The junction point of the valleys at the end of each sub-basin was sampled. From each junction point, 2 stream sediments were collected. The samples were sieved using the wet method into 2 mm fractions, before the fractions were subjected to x-ray fluorescence (XRF) and x-ray diffraction (XRD) analysis. The results obtained from both tests were used to calculate the concentrations of 9 elements (Cr, Ni, Co, Cu, U, Ag, V, Zn, and Cd). The element concentrations are presented in 9 concentration maps after normalizing the concentration values. Some anomalous results were found. The average concentrations of Ag and Cd were nearly 120 and 266 times higher than the background concentrations (6 mg/kg and 16 mg/ kg, respectively). The acquired data also showed interesting average concentrations for the elements Co, Cr, Ni, and U (280 mg/kg, 999 mg/kg, 375 mg/kg, and 12 mg/kg, respectively). All of these anomalous concentrations are discussed and possible reasons for their existence are given.

This study was conducted to identify the mineralogical properties of oak forest and un-cultivated soils at 12 locations in the Iraqi Kurdistan region, which included (Brifca, Gara, and Matin) in Duhok governorate, (Awagrd, Bilah, and Malakan) in Erbil governorate, (Badawan, Bardanga, and Chwarta) in Sulaimani Governorate and (Bakhakon, Hawar, and Sartak) in Halabja governorate. Clay minerals were identified from X-ray diffraction data and peaks. Peak height is used as a rough indicator of the relative abundance of minerals. In general, the expansion of 14A to 17A in ethylene glycol treatment was not detected because measuring started from 5 so thats why we cannot be differentiated between Chlorite and Smectite in that treatment. Swelling chlorite was the dominant mineral in these soils. While the miner clay mineral at that locations were Kaolinite. Mica was identified at all locations, while the dominant type of Mica at forest soils was Muscovite which was obtained from 6 sites, while Mica Biotite was obtained from 4 sites, but in un-cultivated sites, both types of mica recorded at 5 sites.

The Qamchuqa Formation is widely exposed in Kurdistan Region (IKR); north of Iraq. The formation along with the Bekhme Formation form the bulk of the main mountains (anticlines) in the IKR. Among those anticlines is the Ranya anticline, which has a NW – SE trend, where the Qamchuqa Formations has a thickness of about 700 m. The main lithological facies of the formation are limestone, dolomitic limestone and dolomite. We have sampled the uppermost 89 meters of the northeastern limb, by collecting 10 samples of different sampling intervals that range from (3 – 12) m. The ten rock samples were tested by an XRF to measure the concentration of the oxides at each sample. The XRF results showed that the 10 rock samples are limestone with different percentages of oxides. The weighted averages of the oxides in the collected samples have been calculated, and the results showed that the limestone beds along the studied section in the upper part of the Qamchuqa Formations are suitable for the cement industry. The average concentration of CaO and MgO is 55.13 % and 0.26 %, respectively.

New Religion

This article examines the emergence of Zoroastrianism in the Kurdistan Region of Iraq since 2015 as a new religion inspired by Kurdish nationalism, feminism, ecologism and humanism. The author argues that the emergence of Zoroastrianism at this particular time is due to a combination of the rise of the Islamic State in Iraq and the Levant in 2014, legislative change and the importance some Kurdish nationalists historically attached to Zoroastrianism as the suggested original religion of the Kurds. The article outlines the historical context of Zoroastrianism in Kurdistan, and then explores the origins, beliefs and organisational structure of Kurdish Zoroastrianism. Also discussed are the legislative changes enabling the rise of the movement since 2015. This study draws on interviews with Kurdish Zoroastrian leaders as well as with representatives from the World Zoroastrian Organization, the Kurdistan Regional Government’s Ministry of Endowments and Religious Affairs and the Alliance of Iraqi Minorities.ABSTRACT IN KURMANJIJi nû ve pêxistina agir: Baweriya Zerduştî li Kurdistana IraqêEv gotar, li ser peydabûna Zerduştiyê li Herêma Kurdistanê ya Iraqê hûr dibe, ku ji 2015an vir ve wek dînekî nû yê ji netewegeriya kurd, femînîzm, ekolojîzm û humanîzmê îlham wergirtî tê dîtin.

Elpidite belongs to a special group of microporous zirconosilicates, which are of great interest due to their capability to uptake various molecules and ions, e.g., some radioactive species, in their structural voids. The results of a combined electron probe microanalysis and single-crystal X-ray diffraction study of the crystals of elpidite from Burpala (Russia) and Khan-Bogdo (Mongolia) deposits are reported. Some differences in the chemical compositions are observed and substitution at several structural positions within the structure of the compounds are noted. Based on the obtained results, a detailed crystal–chemical characterization of the elpidites under study was carried out. Three different structure models of elpidite were simulated: Na2ZrSi6O15·3H2O (related to the structure of Russian elpidite), partly Ca-replaced Na1.5Ca0.25ZrSi6O15·2.75H2O (close to elpidite from Mongolia), and a hypothetical CaZrSi6O15·2H2O. The vibration spectra of the models were obtained and compared with the experimental one, taken from the literature. The strong influence of water molecule vibrations on the shape of IR spectra of studied structural models of elpidite is discussed in the paper.
