        Structural and morphotectonical evidences of the Golpayegan Region show that there are twoactive faults systems parallel and normal to the Main Zagros thrust. The Shazand fault has 190 kmlength and is a major NW-SE-trending fault that stretched from northwest Shazand to More
        Structural and morphotectonical evidences of the Golpayegan Region show that there are twoactive faults systems parallel and normal to the Main Zagros thrust. The Shazand fault has 190 kmlength and is a major NW-SE-trending fault that stretched from northwest Shazand town towardsouthwestern Isfahan. Around Golpayegan town, the Shazand fault and its branch, Hosseinabadfault make an active area. These faults have reverse and right-lateral motions. The Shazand faultcuts and rotate the Quaternary alluvial fans, displaced Golpayegan and Khomein rivers about 4 kmand uplift the Golpayegan depression. Increase of vertical erosion rate in recent years show thattectonically, the Golpayegan Region is active. Manuscript profile

        The studied area is about 360 Km2. To study the clay minerals of Kordan's area the researcherchose samples from the surface of alluvial fan and the interpretation of XRD indicates thefollowing results : 1-The clay minerals of area are mostly Cholorite and Illite . 2-The kind of area'sCholorite is sedimentary.Which is the result of erosion pyroclastics (TUFF). The origin of thementioned cholorite is heredity. 3-In the downstream of Kordan basin due to the analysis ofCholorite, The amount of the Cholorite has been reduced and the amount of Illite has beenincreased. In such a way that in sample (B1) the amount of the cholorite was 60% and it reduced insample (SM2) to 41/4% and the amount of Illite increased from 35% to 58/6%. 4- The amount ofMontmorionite is little in Kordan .5- In this basin the amount of Fe +2 and Mg +2 is most abundantand the amount of K+ ions is a little. And the climate is dry and semi-dry. Manuscript profile

        In this study efforted Using field Sampling and Sedimentary Analysis to display Textural andCompositional of Sefidrud Near shore Sediments. And with the Sedimentological parameters suchas Mean, Skewness and Sorting, sedimentary process and sediment resource distinguished.Sampling and statistical analyses of the grain size distributions of coast (Back shore, Dunes, BeachRidge, Lagoon, Sand plain) and Sefid Rud river mouth sediments at various locations along thecoastline show that they varied in their mean grain size and values of sorting and skewness. Thestatistical parameters of grain size distributions thus allowed recognition of distinct subenvironments. The size distribution of such sediments suggests that the various processes that areresponsible for their transportation and deposition are wave, current and wind action and scatter plotof standard deviation versus skewness distinguished coast samples are bimodal and river samplesare polymodal. Also with detection of heavy mineral and X-Ray and sediment cross section, showthat magnetite and Illmenite and quartz, feldspar and plagioclase are the most important heavyminerals and rock fragments as respectively Manuscript profile

        In order to evaluation of processes are effective on mixture groundwater of Golgir plain,saturated indexes and mixture curves is calculated and drown for dry period (Shahrivar1385) andwet period (Isfand1385). Considering development of Sulfate and Limestone formations around theGolgir plain, values of saturated indexes of sulfate minerals calculated with PHREEQC computercode in the boundary of the Golgir aquifer. The result shows that they are sub saturated in the mostof samples and different seasons. This means these minerals are solutable in the water. In wetperiod saturated index of the most of samples is decreased because of increasing groundwaterrecharge caused from rainfall. As in sampling of dry period, the most of samples were in conditionsaturated to supersaturate from Calcite and Dolomite. On the base of the Mg/ (Mg + Ca) curveagainst to So4/ (So4+HCo3) curve is determined the water samples of Golgir deep drink wells are inCalcite solution domain but Cement factory wells is placed in south of the Golgir plain, is tend todolomite solution domain. Based on the result of mixture curves, Sulfate and Carbonate mineralssolution processes is the main factor controls chemical mixture of water. Type of sedimentation andgeology formations of region is the most important effective factor on chemical mixtured of water. Manuscript profile

        Population growth and increasing of urbanization make the request for extending new roads.High & Heavy traffic of the east of Tehran enters high pressure on transportation. Network of thiscity and old road of Tehran-Rudehen does not meet this need and remove this problem.Therefore, constructing the new highway which is Tehran – Pardis in the east of Tehran would beneeded. But the new highway prasses the protected area of Jajrood and next to Khojir NationalPark. These areas are those regions including ecologic values as well as national importance,which are chosen for supporting the animal and plant life and also for preventing their gradualdepletion. Therefore, constructing the new highway next to or inside these regions, have potentialImpacts. In this study, for anticipating the effects and evaluating them, and comparing withwidening the present road, pastakia matrice method, was used. The resutls of the research showthat constructing the new highway has the negative consequences less and more positive effectscomparing with widening the present road. For making less the negative consequences ofconsidered plan, managetical strategies has been provided. Manuscript profile

        The Dariyan Formation (Aptian- Albian) is one of the important hydrocarbon reservoirs in theSW of Iran. In this investigation, microfacies, depositional environment and sequence stratigraphyof the Dariyan Formation have been studied in the Sivand and Dashtak anticlines in the north ofShiraz. The thickness of the Dariyan Formation in the Sivand section is 330 meters and in theDashtak section is 263 meters. It mainly consists of limestone and shale interbeds. The lowercontact of the Dariyan Formation with the Gadvan Formation is gradational and the upper contactwith the Kazhdumi Formation is disconformity. Field and microscopic studies of the DariyanFormation have led to recognition of 3 groups and 11 microfacies related to open marine, barrierand lagoon environments. These facies groups were formed in a rimmed shelf carbonate platform.Vertical facies variations indicate the presence of one 3rd sequence. The lower part of TST is in theGadvan Formation and the upper boundary of HST with Kazhdumi Formation is SB1 Manuscript profile
