Surface waters usually" because of contact with different geological formations, relationship with groundwater and surface water resources are associated with highly variable chemical composition. threaten the risk of contamination of water resources. The Shavour River with a long of 90 km in the North West province of Khuzestan is located between the two Karkheh and Dez River's. In this study, understanding of water quality of Shavour River based on different parameters of food, agriculture, as well as its environmental impacts are considered. The case study based on available data on the two water year 90-92 on Shavour Bridge station using graphical methods such as Piper diagrams, Scholler, Wilcox comparing with international standards for water quality analysis was conducted. The results showed that, according to the Wilcox diagram of the river's water is of C3S1class and is pretty good for consumption and agriculture. The Scholler diagram showed that all of the river's water cations and anions are fairly good and the ranges are good and drinking. The Piper diagram of water quality indicated calcium bicarbonate type of water.

For protection of Urmia lake causeway embankment, were used Zanbil and Eslami mountains rocks. Study of these protecting rocks in point of view weathering and demolition are important. The Urmia lake water is very saline and penetrating saline water to rocks texture and salt crystallization is the one of main reasons for rocks weathering and demolition. In this paper the influence of litological aspects on the strength and durability of volcanic rocks in Urmia Lake Causeway based on field studies and sampling and pertographical studies and some physical and mechanical tests was considered. Rocks of west side of the causeway were obtained from Zanbi Mountain and the rocks of east side of the cause way were obtained from Islamic island. The most of used rocks are consisted of trachyte, andesite, basalt, tephrite, agglomerate and latite. The Islamic island rocks, except andesite, experienced more weathering. Texture properties like particle size and weathering type has more effect on strength and durability on used rocks. Increasing of particle size is causing decrease of strength and durability. The rocks of eastern side of the causeway due to porphyry texture and the occurrence chemical weathering before using in causeway, with high porosity and high water absorption is severe and deeper than weathering of western part rocks. Also the existence of clay minerals that was produced from weathering is caused low density in the Islamic island rocks.

The studied section (Guri Member) is located at Mansour-Abad area, SE of Jahrum. This section, with a thickness of 175 m, consists of cream, thin to medium bedded limestone and gray marl. The lower boundary with green marls and red silts of Razak Formation is conform and the upper boundary changes gradually to Mishan Formation. The thin sections and washed samples studies lead to recognition of 40 genus and 21 species of foraminifers. Based on the association of index species such as Operculina complanata, Neorotalia vennotti and Miogypsinoides dehaariti an assemblage biozone number 1 was recognized Operculina-Nephrolepidina-Miogypsina assemblage zone. which is the compareable with biozone- 64 of Wynd. The red alga Lithophyllum sp. was also recognized. Based on the foraminiferas, the age of Guri Member in the studied section was determined as Aquitanian- Burdigalian. Based on Facies and sedimentary environment, 13 micofacies were recognized which have been deposited in three environments- outer, mid, and inner ramps, and can be referred to restricted marine, shoal, lagoon and tidal flat. Therefore, the sedimentary environment of Guri Member is a carbonate platform of a homoclinal ramp which begins from the coast, then crosses a bioclastic barrier and ends in semi-deep marine environment.

The Khanik-Qazan placer deposit is located at 82 km northwest of Urmia city, western Azarbaijan province. This area is a extremity northwest part of the Sanandaj-Sirjan structural zone. Microscopic studies show that ilmenite, ilmeno-magnetite and magnetite are the main ore minerals and layered gabbros are the main source rocks of these ore minerals. The prospecting activities in this area indicated good results relating to the existence of economic potential of ilmenite and titano-magnetite placer resource. Investigation of particles size distribution of representative total sample of the placer, indicated that 68 vol% of placer sample has sand size (< 2.36 mm), and the residual portion has gravel size (> 2.36 mm). An exploration plan was designed according to field geology studies, preliminary chemical analyses and prepared topographical and geological maps (1/5000 and 1/2000 scales). Eight trenches (a total length of 778.5 m and 1747 m3 total volume with 131 representative samples) and 43 test pits (a total depth of 140.3 m and 362 m3 volume with 121 representative samples) were drilled during the exploration phase. Geochemical analyses (carried out by XRF method) show that the grades of TiO2, ranges from 0.6 to 3.29 wt% (1.72 wt% in average) in exploration trenches and 1.01 to 4.83 wt% (2.39 wt% in average) in test pits. Vertical cross sectional method and geostatistical methods were used to reserve estimation of the placer ore. The estimated ore (in proved category) were measured 12 Mt with TiO2 grade of 2.338 wt% by classic method. Based on liberation degree study, suitable particle size for grinding of sand and gravel fractions were determined -500 µm and -250 µm for sand and gravel fractions, respectively. Mineral processing (ore dressing) studies show that the fraction +70 mesh (+210 micrometer) of sandy part of the Khanik-Qazan palcer ore have high concentrability, so that, an ilmenite concentrate containing 40.11 wt% TiO2 and recovery percentage of 86.41 are produced by using spiral classifier as primary concentrator and shaking table as final concentrator.

The one of the most important petroleum source rocks in the Zagros basin is the Pabdeh Formation that has been investigated by geochemical techniques. The aim of this study was to assess the quality of organic matter, evaluate thermal evolution and highlight Pabdeh Formation potential as a source rock of Ramin oilfield located in Dezful Embayment. Based on HI versus Tmax and HI versus OI diagrams were used in classifying the organic matter in the formation indicating the presence of Type II kerogen. Most samples of the Pabdeh formation have Tmax values more than 435ºC indicate that the shale of formation is thermally mature with respect to petroleum generation. Hydrogen Index (HI) values range from 150 to 350mgHC/gTOC and S1 + S2 yields values ranging from 11.98 to 31.06mgHC/g rock, suggesting that the shale have oil generating potential.The TOC of shale samples of the studied Ramin Well no. 4 ranges from 1.82 to 3.5%, an indication of a very good source rock of terrestrially derived organic matter. So, investigation of the variation S1 + S2 and TOC parameters indicated that Pabdeh Formation (in the well) is assessed a good source rocks in producing hydrocarbon. Also with T max examination showed that formation is mature enough to generate hydrocarbon and has yet entered oil generation window.

Prediction of the spatial distribution of rainfall is essential for establishing the water balance and a good estimation of water availability, especially in mountainous areas because of complex rainfall gradient and scarce number of climatological stations. This study was conducted to evaluate the rainfall spatial distribution of Urmia region by interpolation methods. Data related to 38 climatological stations were used and three methods, IDW, Kriging, and Co-kriging were investigated. After normalization of data, variograms were computed. The least RSS and the most powerful spatial structure were considered as criteria for selecting the best model for fitting on experimental variograms. Cross-validation and RMSE were used for selection of best interpolation method. Results showed that Cokriging method, with elevation parameter as an auxiliary variable, has the least error which may be attributed to the significant correlation between the elevation and annual precipitation at the study region. Due to the mountains region and suitable condition for rainfed farming, so using cokriging method and GIS, high- resolution maps of rainfall distribution and determine rainfed farming region was prepared.

Zargoli granitoid is located in the northwest of Zahedan and south-east of Iran. This granitoid is composed mainly of granodiorite. Mineral chemistry of biotite was studied in granodioite rocks with the aid of EPMA and the results of this study were compared with the mineral chemistry data of biotite in Zahedan granitoids. Total amount of aluminum in comparison to Fe / (Fe + Mg) ratio in biotites of Zargoli granodiorite indicates the presence of aluminous upper crust materials (metamorphosed sediments) in magma by digestion process. Total Al amounts of biotites of Zahedan granodiorite were lower than those of Zargoli granodiorite and it is indicative that the magma of Zahedan granodiorite is less contaminated by crustal rocks. The study of mineral chemistry of biotite determines that the studied granodiorites were I-type and composed of a calc-alkaline granitic magma. This magma climbed in a subduction environment and contaminated with sedimentary rocks of the upper crust. The chemistry study of biotite determines a relatively high oxygen fugacity (10-12 to 10-13 bar) and an oxidant conditions for granodioritic magmas studied. The amount of oxygen fugacity in the Zahedan granite magma is obtained from 10-14 to 10-15 bar which in fact represents a weak oxidizing condition in the Zahedan granite magma.

Natural hazards such as earthquake is as the nature disasters that have many financial and human losses every year. Today advances in science and technology, provided appropriate fields for the study and reduce these natural hazards. In this respect, the geographic information along with decision support tool used to assess the risk of earthquake. The aim of this study was to investigate the effects of different factors in the creation and earthquake hazard zonation of earthquake in central part of the Semirom city. For this purpose affecting factors were binary compared using analytical method by indicating the weight of each factor as indicator for their effects in occurrence of earthquake. Accordingly, the earthquake regionalization hazard map was prepared to the use of weighed information layer and weighted coefficient of each factor. Results of this study show that the analytical hierarchy method is precise method for evaluation of earthquake potential due to the use of binary comparison affecting factors and considering numerous factors for earthquake evaluation at the same time in comparison to the other prevalent method. The results indicates that the percentage of high and very high hazard class is 49.72 percent in AHP method.

The Chenar area of Khomein is located in the Sanandaj-Sirjan tectonic zone and in the Malayer-Isfahan metallogenic belt.This region has the mineralization of Pb, Zn, Ba, Ag and secondary mineralization such as quartz, hematite, limonite, calcite and malachite. In a geochemical study of drainage sediments, we were taken 127 samples and were analyzed 14 elements such as As Ba, Ca, Ce, K, Mn, Pb, S, Sr Th, U, W, Zn, and Zr and anomaly was determined by Lopiliteh and the singularity index method., The majority of elements are in the background according to anomalous maps by Lopiliteh method and the anomalies are seen only in limited areas of the region. The hidden anomalies are better identified in the maps of singularity index method and there is a good relationship between the derived anomalies and the position of the Sangol Pb-Zn mine in the region. The enrichment of elements such as As, Ba, Ca, Ce, K, Mn, Pb, S, Sr, Th, U, W, Zn, and Zr is shown by the singularity index method in the region. In this study, two districts with anomaly were identified as the future exploratory target.
