        Dalaki sulfur springs (Oba, Garuw and Rahdar), are hot sulfur springs in Bushehr province. The use of these hotwater and sulfur springs for agricultural and some diseases treatment by area residents has a long history. Originof these springs likely is mixing oil saline water of Asmari reservoir rock of Dalaki oil field with water sulphateGachsaran formation place ran out are springs. This saline water has mixed with spring's water by fault systemQatar-Kazeroun that strongly influence on region. For evaluate these springs Hydrochemical state (determinetype of water and identify the major elements and some trace elements) and its therapeutic potential in the 1389sampling of spring water were performed. Type of these springs water is Na-Cl. According to study conductedBalneology of these spring water can be effective in the treatment of gastrointestinal diseases, skin and hairrickets, and the nerves. These springs despite many health benefits, due to downstream water quality degradationand their pollution and their hydrogen sulfide have devastating environmental impacts also. Manuscript profile

        The Dehno granite massive is located in the East Dehno village and southern Khomein city and within themetamorphic Sanandaj–sirjan Zone. The composition of these rocks include: granodiorite, quartzdiorite(tonalite), monzogranite and leucogranite. Quartz, alkali feldspar, plagioclase, biotite, andalusite, hornblendemuscovite, tourmaline, zircon and apatite are examples of the existing major and minor minerals in theseintrusive rocks. This body is host the tourmaline bearing silica veins and dykes and mafic enclave microgranolaraplitic (several) and doleritic (seldom). Mineralogy and geochemical studies this rocks indicated mantlePeraluminium and calc alkaline and mixing origin(melting of the oceanic crust of the Neo-Tethyan belowCentral Iranian Microplate) and anatexi melting (the melting of continental crust sediments) and rocksenrichment LILE elements such as granite(Rb, K, Cs) and the concentration of depleted elements, particularlyHFSE Ti, Nb and P is consistent with the pattern of granites associated with the subduction setting and from thetectonic environment aspect, they are considered as the volcanic arc granitoids (VAG).

        The pollution of the environment with toxic heavy metals is spreading throughout the world along with industrialprogress. Removal of heavy metals needs advance chemical technology and is more expensive too. The cheaperalternative for this is the bioremediation using heavy metals resistant microorganisms. In this study, 5 heavymetal resistant bacteria were isolated from electroplating effluents collected from Islamshahr. The isolates grewwell on nutrient agar containing 1 mM of chromium (Cr). The resistant isolates were identified on the basis ofmorphological, biochemical and physiological properties. Finally its molecular identity was revealed through16S rRNA analysis. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolates belongto the following genera: Comamonas, Acinetobacter and Acicovorax. The minimum inhibitory concentrations(MICs) of the isolates were determined. All the isolates showed high resistance to chromium with MICs rangingfrom 4-6mM. The results suggest that the isolated strains obtained from effluent owing to its high resistance tochromium have a great potential to be employed for bioremediation of chromium contaminated effluents.

        This is 165 m thick Mozduran formation, as a carbonate and siliciclastic strata, in Saleh-Abad section, consistsof carbonate, sandy lime and siliciclastic rocks. Mozduran Formation relates to (Oxfordian-Kimmeridgian) age,locates conformably on Kashafrud and beneath Shourijeh Formation. The purposes of this study are: 1.The studyof vertical and lateral changes in litho strata units, 2. identification, detachment and naming microscopic faciesbased on thin section, 3.The explain ton of digenetic events based on petrography events, 4.The explanationsedimentation history with using lithofacies properties and presentation the sedimentation model. Based onpetrographic studies of 50 thin sections and two facies collection have been recognized. The Limestone faciescollection consists of bioclastic grainstone pessessy Milliolidae (facies A, a lagoonal environment), sandy ooidgrainstone, Bioclactic ooid grainstone, ooid grainstone with bioclast (facies B, a barrier environment), andTerrigeneous facies collection which is mainly composed of chert arenite and sublitarenite (facies C, a tidal flatenvironment). According to lithofacies, Mozduran Formation depositional environment could be interpreted as acarbonate plat form. Manuscript profile

        Base-metals sulfide mineralization in Galena and sphalerite forms with little amount of pyrite, in Mobarak andElika formation have been occurred in the studied region. Chemically, all deposit phases have compositinghemogen region. Mineralization has been followed the fault general process in the region, and the main texturesin the ore are vein texture and open space filing. Genetically, studied deposits are epigenetic.

        The studied region with 3750 km² is located in 65 kilometers in south-east of Tehran and 140 kilometers in westof Semnan. In this study, physical and chemical characteristics and engineering marl which are sensitive toerosion with various forms of Surface, Rill, Gully, and Channel Erosion have been investigated. It was taken 14samples of marl surface with mostly Gully Erosion. The results of chemical analysis showed that the soil of thisregion is salin,alkali soils, from the viewpoint of engineering, soil samples within the SM, SW, SP, and SCM areconsidered. The granulometrie of soils showed that they are loamy to fine loamy. So they are susceptible toerosion. According to analysis to detect physical properties, chemical and mechanical engineering marl markedbetween amounts of salt, gypsum and lime are significant differences and these three factors can be an importantfactor in distinguishing erosion problems considered.

        Koh-e- Siah anticline is located at 20 km NE of Dehdasht city. The studied area is very important from aspect ofwater resources in Kohgilooye & Boerahmad province. So the karstic resources as a strategic resource is noticedthe government’s s province. Structural elements such as, faults, joints, folds and bedding patterns play animportant role in the karstification and development of Karst water resource. In this research emphasis is givento investigating whether structural elements and topographic factors, mapped using remote sensing, aerial photointerpretation and derived from the geologic map can be correlated with hydrologic phenomena. With thisassumption, various types of thematic layers have been prepared and integrated in a GIS environment due to thegood correlation between above mentioned factors and hydrologic phenomena it was concluded that tectonicelements have a positive influence on the groundwater occurrence and they act as transmission routs in thelimestone bodies.

        The Pirtaqi dam will be constructed in 50 km eastern of Miyaneh and 45 km south-western of Khalkhal, onQezel-Oezan River in Ardebil province. For the Pirtaqi site were purposed two dam site, named 15 and 15A. Inthis paper by using multi-criteria evaluation of AHP (Analytic Hierarchy Process), the preferred dam site fordam construction had presented. For selection of best dam site have been descript 8 criteria and 26 sub criteria,then had evaluated by using Super Decision software. On the base of preferred evaluations for sub criteria thathad depended to Q, RMR, and DMR classifications, quantitative values of RQD, SPI and GSI, permeability ofbanks and bed rock, uniaxial compressive strength, deformation modulus's, stability and conditions of powerplant tunnel, major joints and faults in dam axis, excavation volume, depth of weak pyroclastic rocks andalluvium texture, the 15A dam site has higher scores of pair wise comparison matrix and has been presented forpreferred dam site Manuscript profile
