        Planners and development policymakers mention tourism as the main pillar of development in different countries. Today, tourism can create employment, increase income and ultimately prosperity and improve the livelihoods of the people. This research, which aims to determine the strategic position of the tourism industry in Takab, is an applied research and Delphi descriptive research method. The model used in the research is a comprehensive strategic management model based on SWOT technique. Research data was collected using the Delphi technique from 16 experts, officials and administrators of the tourism area of Takab city and analyzed. In the results section, while outlining the vision, mission and objectives of the proposed development, the results of the evaluation of internal and external factors have also been presented. This result suggests that the tourism industry of this city is in a defensive position and requires special attention of the authorities. Manuscript profile

        The presence of hot springs, travertine outcrops, hydrothermal altered area and active tectonic in the north-east of Takab city in the West Azarbayjan province indicate that there is a geothermal system in the area. In order to characterize the geological structures associated to the geothermal system in the region, a gravity survey was carried out in 140 stations which covered an area about 600 km2. Necessary modifications such as Bouguer, topography and free air were applied over data to obtain complete Bouguer anomaly field. Then, residual gravity anomaly field was calculated by subtracting the regional gravity field from complete Bouguer field. The regional gravity field was calculated by fitting a three-order polynomials surface over the complete Bouguer field. The calculated residual gravity map shows two negative anomaly zones (A1 and A2) in the study area. In geothermal exploration, negative gravity anomalies are considered as probable reservoir of geothermal systems. The horizontal and vertical derivative maps show complicated fracture zones in the study area. To obtain more information, the depth estimation carried out using Euler method. Estimated depth for the top of negative anomaly source in zone 1 is between 1000 and 2000 m. Finally, 3D inversion of the data was performed using Li and Oldenburg algorithm to show an image of the reservoir in the depth. The results of 3D inversion show a significant negative density contrast that occurred only in zone 1. Therefore, the reservoir of the Takab geothermal system is located in the depths between 3000 and 5000 m in A1 anomaly zone. Manuscript profile

        3 - The Study of mineral chemistry, tectonomagmatic setting and petrogenesis of plutonic bodies in Sursat Complex, NW Takab, Iran

        The plutonic bodies occurring in Sursat complex are some parts of plutonic rocks of Sanandaj- Sirjan Zone. Based on the field observations and microscopic studies, rocks of the study area are consist of hornblende gabbro, quartz diorite, monzodiorite, granodiorite and tonalite. The EPMA analyses of minerals such as amphiboles (in granodiorite and monzodiorite), plagioclases and alkali feldspars indicate that amphiboles are magnesiohornblende, plagioclases are albite and oligoclase and alkali feldspares are orthoclase. Geochemical studies indicate that monzodiorite unit (Turke Dare and Khangholi bodies) are metaluminous I-type and calc-alkaline in nature. They are plotted in volcanic arc granite (VAG) region with 87Sr/86Sr and εNd values equal to 0.70448 and -0.12. All evidence represent that the monzodiorite were generated from a magma which was derived from mantle affected by assimilation and contamination processes. Granodiorite unit (Pichaghci, Hamzeh Ghasem and Northeast Khangholi bodies) represents I-type, metaluminous to peraluminous and calc-alkaline characteristics and is plotted in VGA field of magmatic arc. The 87Sr/86Sr and εNd values are equal to 0.70529 and -2.82 respectively. So these granodiorites were generated through mixing processes of a mantle magma with crustal sources. Tonalite–trondhjemites group are I-type, tholeiitic, peraluminous according to the low value of Mg# (2.9-11.6), Cr (20-46 ppm) and Ni (1-2.4 ppm) contents. They are also low in LA/Yb, Sr/Y, and Nb/Ta. The slight negative anomaly in fractionated patterns of the rare earth elements (REE) and very low depletion in Eu, indicate that these rocks were resulted from amphibolitic crustal source that were previousely generated from thickened mafic crust or from basaltic plate in low pressures at shallow depth in the presence of abundant plagioclase.

        Arsenic is one of the heavy metals having harmful effects on human health if enters into the environment and water resources, so the major challenge of arsenic exposure is related to drinking water. The study area is Takab watershed in West Azarbaijan, which includes two large Zarshouran and Agh Dareh gold mines in Carlin type. Carlin gold mines are sulphidic that are able to pollute the downstream environmental resources such as arsenic. In this work, the carcinogenic and non-carcinogenic health risks associated with arsenic was evaluated for the human community, who are living in Takab watershed and are exposed to arsenic through oral and dermal pathways with contaminated water sources . 45 water samples were randomly collected from surface and groundwater resources in the study area with regard to expert judgment and the distribution points, analyzed by ICP-MS method. Then, the health risk was assessed using by target cancer risk (TR), risk coefficient (HQ) and index hazard (HI). The total results showed that arsenic contamination is derived from volcanic activities and Quaternary alteration and gold mining activities in the east and north of the region. Most of the samples were revealed a range of 9-10 and -100 to -250 mV as pH and oxidation-reduction potential, respectively, which indicates the predominance of arsenate species (As5+) in the form of H2AsO4-. HQ and HI values are more than 10 in 52% of the samples, which indicate the high health risk in people living in the study area. Carcinogenic risk level varies from 0 to 2×10-7, which shows no carcinogenic risk to very high risk by arsenic contamination in water resources. Overall, there are both risks of carcinogenesis and non-cancerous impact in the east and north of the region for intake by ingestion, drinking and skin contact due to water contamination from the natural and anthropogenic sources. Therefore, it is recommended to pay special attention to continuous monitoring for potential contaminant, different methods for preventing exposure to polluted water resources and treatment methods in order to minimize the health risk of the population.
