        1 - Processing of exploration data in Zarshouran area, modeling of ore body and mineral resource estimation
        Arash Gourabjeiri pour Bahram Abolqasemi Alireza Najafi Mahnaz Taheri
        Zarshouran zone is located in South East of west Azerbayjan. From geological point of view this zone is a part ofAlborz-Azerbaijan zone and Precambrian hostrock forms the prevailing outcrop of Zarshouran zone which iscomposed of carbonates and acidic volcanic rocks to i More
        Zarshouran zone is located in South East of west Azerbayjan. From geological point of view this zone is a part ofAlborz-Azerbaijan zone and Precambrian hostrock forms the prevailing outcrop of Zarshouran zone which iscomposed of carbonates and acidic volcanic rocks to intermediate rocks. This sequence covered by sharpunconformity from red layers of Oligomiocene. The most important structure which effects in forming the oredeposit, is Imankhan anticline and the main structural features in Zarshouran ore deposit is ductile and brittlestructures and among these the main faults with the direction of North-West and South-East are probably inconnected with mineralization. Gold mineralization in this ore-deposit from different point of view is similar toepithermal mineralization in sedimentary rock especially in calcareous rocks (Carlin type gold deposit). Silicic,silicic argillic, sercitic-argillic and alunitic alteration are visible in the zone. The datas of different stages of thiszone have been gathered in GIS base and processed with Data mine Studio 3 software. At first 1427 geochemicalsamples were studied and the highest mineralization potential of the zone was specified and gold paragenesiseswere distinguished. Then based on drilled boreholes and statistical studies of datas sections and estimation spacewere specified and using the best method of estimation, ordinary kriging, and reservoir evaluation have beendone. Finally, based on different parts of mineral ore thicknesses and estimation error, the best drilling points forcomplementary survey of zone in the nets of 50,100,200 meters were specified.

        All countries are trying to reuse the waste water. In this study, in order to feasibility of wastewater reuse,parameters such as temperature, turbidity, pH, EC ,COD ,BOD ,TSS ,TDS, SAR, carbonate, bicarbonate,alkalinity, chloride, nitrate, sodium, ammonia, magnesium, calcium, total difficulty, phosphate, fecal coli inwastewater of Anbaj treatment plant (Shemiranat region) were investigated seasonally between 2010 and 2011and restrictions on the reuse of different uses were identified.Quality of studied wastewater for agriculture was in accordance with Iranian Environmental standards except inmicrobial parameters. EC, TDS and bicarbonate has low to average limitations for irrigation. Based on Wilcoxdiagram, studied wastewater is located at medium stage (C3 S1) considering alkalinity and salinity. The studiedwaste water has some problems for aquifer artificial recharge considering the ammonia parameter. According todischarge standards for surface waters ammonia and calcium have some constraints. BOD and ammonia couldn’tbe used for aquaculture, environment, recreational and wildlife usages. The studied waste water wasn’tappropriate for industrial use and is classified in waters with medium quality by power ministration. Manuscript profile

        3 - Seismic geotechnic and dynamic soil behavior analysis of Bahabad city, South East Yazd
        Ahmad Adib Akram Kosari
        Bahabad city is located in south Yazd province of Iran, about 200 Km far from east yazd city. In this study,seismic microzonation of the city is done based on the area seismicity with specific return period, and by usingobtained data of the 5 boreholes to determinate dy More
        Bahabad city is located in south Yazd province of Iran, about 200 Km far from east yazd city. In this study,seismic microzonation of the city is done based on the area seismicity with specific return period, and by usingobtained data of the 5 boreholes to determinate dynamic soil behavior and ground response against earthquake.To analyze site effect precisely, we used EERA program and provided microzonation maps by Kriging methodand using ArcGIS software. The study showed that the city center has a higher amplification factor than the otherparts. The area classified to two ground type: IIb (hard soil with thickness more than 30 m) and IIIb (moderatedense soil) based on standard 2800 of Iran. Maximum acceleration and amplification factor of the surface arehigher and decrease to go around. The center of the city has hard soil with thickness more than 30 m (IIb) andtherefore, maximum spectral acceleration. This trend decreases into the around. Manuscript profile

        There are several quarry mining methods which are phased out due to lots of difficulties to use and lack oftechnologies. Selecting the proper quarry mining method is a kind of Multi-Criteria Decision-Making (MCDM)problem which needs to be managed appropriately. Selection Process deals with some factors affecting onselection approach such as revenue, safety, environmental issues, losses, mining period, etc. The aim of thisresearch is to choose the proper quarry mining method in Iranian quarry mines using Fuzzy-Topsis approach.There are some conventional quarry mining methods in Iran including Plug and Feather, Controlled BlastingTechnique, Expanded Powder, Diamond Cut Wire methods. Achieved results from analysis and investigationsshowed that the Diamond Cut Wire method is the most proper quarry mining method for Iranian quarry mines. Manuscript profile

        In this paper, geostatistical methods has been used for optimization of groundwater observation wells network inTabriz plain, North West of Iran. Existing network of observation wells in Tabriz plain have been formed of154Wells and the distribution is not optimal. Data of existing observation wells network and also quality andquantity network is used in order to optimization. By Comparison of different geostatistical models, forsimulation of water level changes in Tabriz plain and choosing the best model, three methods of reduce, increaseand change in the location of wells was followed to optimize existing network. The results showed that byreducing the number of wells to 64%, Water levels in areas without information can be estimated withreasonable accuracy. Increasing the number of wells did not improved statistical criteria, but change in thelocation of some wells causes increase of accuracy of kriging fitted to the data. Manuscript profile

        In order to study the stratigraphical correlation and environmental changes of the Ruteh Formation deposits inthe Alborz Region, four stratigraphical sections in the central Alborz Region (South of Nowshahr, Chalus, andAmol) and Eastern Alborz (Ghoznavi) were studied. Lithology of the Ruteh Formation in the Alborz Region arealmost limestone rock and the deposits of the Formation are specified by detrital facies and carbonated facies(limestone and dolomite). The deposits have a great thickness and their thickness is variable in different sections.Therefore the Ruteh Formation thickness in Manjir section (South of Nowshahr) is 493m, and 200m in the North– West Harijan section, 480m in Amol section and the thickness reaches 115m in Ghoznavi (Eastern Alborz)section. Ruteh Formation in these sections was determined at Artinskian- Murghabian age based on the fossilsextracted. Based on the field study, and thin sections, four facies including Tidal flat, Lagoon, Braaier and Openmarine were identified. Manuscript profile
