Kazakhstan is among the world leading countries in terms of reserves and production of lead and zinc. There are large ore regions with polymetallic mineralization; these are the deposits of the Atasu and Uspensky ore regions in Central Kazakhstan. The former are genetically related to the final (taphrogenic) phase of the development of the large orogenic structure in the Central Kazakhstan (the Devonian volcano-plutonic belt), with the period of Late Frasnian-Famenian-Early Carboniferous formations of thick carbonate and carbonate-terrigenous sediments, including significant reserves of stratiform lead-zinc ores. Polymetallic mineralization of the Uspensky zone is singled out as an independent genetic Alaygyr type, and the tectonic nature of the ore-bearing Uspensky zone, as well as mineralization of this type, is still the subject of constant discussions. In this regard, the comparative characteristics of the Dalnegorsky and Uspensky ore regions, which have certain similarities in geodynamics, magmatism and metallogeny, are of great importance not only for solving the issues of the general patterns of formation, factors and criteria for controlling lead-zinc mineralization but also for an objective assessment of the ore potential of these and similar areas with polymetallic mineralization. Research methods: comparative analysis of the results of petrographic, chemical and mineralogical studies of ores enclosing near-ore metasomatically altered rocks and intrusions of different age and composition.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"114 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139134686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation comprises of rhythmic alternation of medium to thick-bedded marly limestone with marls. Petrographic investigation of marly limestones is on 60 thin sections and showed a variety of pelagic (open sea) faunas such as; ammonites, planktonic forams (Globigerina), radiolarians, calcispheres, ostracods, bioclasts, echinoderm plates and rare calpionellids. Peloids are the only non-skeletal grains components. Depending on detailed microfacies analysis of limestones, three main microfacies types and nine sub-microfacies are identified in the studied sections of the Sarmord Formation, these facies were incorporated into one facies association type relating to their environmental interpretation, that is basinal facies association. X-ray diffraction analysis of selected marl samples, displayed that the main clay minerals in the Sarmord Formation are illite, kaolinite, chlorite and mixed-layers of illite – chlorite. The high abundance of illite indicates that hot-arid climatic conditions prevailed during the deposition of the Sarmord Formation in the study area. From all of the petrographic, facies, textural and mineralogical analyses, it is concluded that the Sarmord Formation in the northeastern Iraq, was deposited in deep water, basinal (outer ramp) environment.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"62 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139130716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rocks of the latter are used as the raw materials in five cement plants in Sulaymaniyah Governorate. The rocks of the Khurmala Formation were sampled near Kalka Smaq village along the road which crosses Haibat Sultan Mountain to perform an industrial assessment of the rocks. The sampled section is 65 m thick; 13 samples were collected as channel samples with regular intervals of 5 m. In the field, the samples were lithologically described and checked with HCl acid. The samples were powdered, and subjected to XRF to detect the main oxides in the samples. The obtained results of CaO, MgO, Fe2O3, Al2O3, Na2O, K2O, SiO2, SO3, Cl, and L.O.I. as weight percentages were checked with Iraqi standards to find for what industrial uses can be suitable.

A stormwater retention pond was built as a part of the construction plan to prevent the occurrence of floods downstream of the development sites. However, poor monitoring and maintenance of the pond caused water contamination, which had bad effects on the nearby environment and lake ecosystem. Therefore, this study was conducted to assess the current water quality in the pond by using a combination between Multispectral Unmanned Aerial Vehicle images and in-situ sampling. Four water quality parameters were investigated, namely turbidity, dissolved oxygen, temperature, and pH. Aerial images were taken using a multispectral aerial mapping camera attached to UAV. The in-situ testing was performed on the same day of image capturing at 5 different locations. According to the results, it was found that the pH and water temperature were within the normal levels with maximum and minimum values of 7.34 and 6.94 for pH and 28.39oC and 28.04oC for temperature, respectively. Turbidity readings appaired with a significant variation with a maximum value of 30.9 NTU at the lake outlet and a minimum value of 18.8 NTU at the middle of the lake. Dissolved oxygen concentration was noticed to be low, with an average value of 4.3 mg/l. Water quality mapping showed the concentration distribution of each water quality parameter along the lake surface. In each map, the differences in terms of colours were found to be not significant because of the size of the lake, which is relatively small, as well as because of the small differences in terms of water quality ridings at each sampling point.","PeriodicalId":14847,"journal":{"name":"Iraqi Geological Journal","volume":"19 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139130182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was shown through the degree of contamination of heavy elements in the falling dust that it generally falls into the classification (Considerable contamination). it was found through the hazard quotient and hazard index of the elements that there are non-carcinogenic health risks, including the children's category for arsenic and lead elements.
