Polycentric city- regions are the result of the increasing processes of growth in different spatial configurations. Such phenomena are particular type of spatial system that have their unique and distinctive characteristics. Misunderstanding the nature of Polycentric city-regions and their specific guidance and control mechanisms especially in developing countries, would prevent them of experiencing sustainable spatial development. Traditional planning approaches are unable to face challenges presented by such city- regions, while insisting on their continuation would lead to inextricable problems. This is despite the fact that the strategic spatial planning might address the challenge properly. The purpose of this article is to explain and to clarify the concept of city- region in developing and developed countries; to thinking about the consequences of city- regions’ expansion; and to discuss the eligibility of spatial strategic planning as a responsive and applicable procedure to face the challenging nature of Polycentric city- regions. This article is based on explanatory research methodology, which is followed by an analytical description of events in order to explain their relationship within the framework of systems approach. So, firstly, the theoretical and experimental frameworks related to the “polycentric city region” would be reviewed; secondly, the spatial strategic planning approach would be explained; then the challenges of guidance and control mechanisms in polycentric city- regions would be clarified; and finally, the key and strategic issue to address those challenges would be discussed. The output of this article is the analysis of major characteristics of polycentric city- regions and the explanation of how the guidance and control mechanism of such city- regions can be assumed to be within a spatial strategic planning approach.

In order to study the effect of urbanization growth on temperature and precipitation in Babolsar Station in the period 1989-2008 and show differences, two types of urban and non-urban stations were selected. According to the criterion of distance up to 500 meters from the city border, Babolsar Station was selected as the urban station, and based on the criterion of at least 2 km away from the nearest town, Gharakheil, Sari, and Nowzarabad stations were selected as non-rural ones. Urban development index and Shannon entropy were used to measure urban development and Mann-Kendall was used to study changes in climatic parameters. The results of the physical condition of Babolsar Station indicate a dramatic fragmented physical development. Analysis of the trend of temperature and precipitation showed that total monthly precipitation indices, the number of days with precipitation of 1 mm or more, the average temperature, and the average minimum daily temperature follow a significant trend and gradient of their changes in the urban station of Babolsar is more specific and steep than non-urban stations. Kendall Tau of the temperature and precipitation changes show that climatic data of Babolsar Station are influenced by the urban microclimate and the environment around the station. Since Babolsar Stations was formerly located outside the urban area and then became an urban station and urban development of Babolsar caused changes in temperature and precipitation of this station, many studies cannot use these changed data as a result of urban development around the station and the results obtained from data of Babolsar Station will be generalizable to urban conditions expanded around it.

Over the past decades, global warming has undergone significant changes in weather and climate cycles, such as increased water vapor in the atmosphere, increased Precipitation and reduced Precipitation. This research was designed with the aim of modeling Precipitation in the region of West Asia under the influence of climate change. For this purpose, the Precipitation data of the West Asia region for the period 1961-2015 and 2016-2045 was downloaded under the A1B scenario of the HADCM3 model from the Canadian Climate Change Center (CCCSN). In the next step, using the R2 and RMSE statistics, the accuracy of the model was evaluated and the modeling results were of great accuracy. The slope of precipitation, using the sen's method, showed that in January, February, July and August, precipitation would increase and decrease in other months of the year. The Precipitation season with the Man-Kendall method also shows that the prevailing trend is decreasing throughout the year, and the incremental precipitation will only be related to precipitation and 24-hour Precipitation. Also, the results of this study showed that Precipitation in the Mediterranean and Sudanese systems is increasing, and this increase will not have a good prospect for the aquatic environment of the region, as 1 - areas with increasing trend during the warm year will evaporate the Precipitation received from the surface and An increase in precipitation in the cold season also causes flooding of the rainforest.

The Boroujerd granitoid complex is part of Sanandaj-Sirjan structural zone and located in the West of Iran. This igneous complex in the Upper Jurassic (20 ± 167 million years) intruded to older metamorphic schist. Hornblende hornfels and pyroxene hornfels metamorphic facies has created around Boroujerd granite body. Migmatites phenomenon in parts of proximity halo observed that evidence of specially increased geothermal gradient in the Boroujerd aureole contact metamorphism. Quartz, feldspar and biotite is main minerals in leucosome migmatites parts, so orthopyroxene , garnet and sillimanite has fond. In the melanosome migmatites parts orthopyroxene +garnet+sillimanite+cordierite +corundum paragenesis indicated temperature and pressure above the pyroxene hornfels facies and show low pressure bounds of the granulate. Associated garnet-biotite cation exchange, temperatures of 635-720° C, in the 3-4 K bar pressure accepted for migmatites. This temperature and pressure higher than normal and its proximity changes the crystallization of certain minerals such is corundum.

The amount of the Total Organic Carbon (TOC) is one of the most important parameters in geochemical evaluation of hydrocarbon source rocks and subsequent petroleum system modeling. We proposed a three- step approach in predicting and modeling TOC content from well log data. Initially, TOC evaluated for 92 core and cutting samples by Rock-Eval pyrolysis method. In the next step the TOC were predicted using intelligent neural network with back propagation algorithm from well log data. Correlation coefficient between the network output and target data in the training, validation and testing steps for the optimized model is 0.9, 0.88 and 0.91 respectively which indicate the satisfactory approach in predicting TOC. Finally geostatistical methods were used to 3D modeling of this parameter in the field study. The proposed methodology is illustrated using a case study from the world's largest non-associated gas reservoir, the South Pars Gas Field, the Persian Gulf basi

Khak- Sorkh iron deposit lies about 42 km west of the Yazd city. The area is located in the central part of the Urumieh-Dokhtar magmatic belt and is covered by upper Triassic-lower Jurassic sedimentary units and Oligo-Miocene intrusions. Intrusion of Oligo-Miocene granitoids into Cretaceous limestones resulted in iron skarn mineralization. Magnetite is the main iron ore mineral; minor copper mineralization also occurs locally as malachite staining at surface. Two main structural trends can be distinguished: NW-SE which follows the main trend of the Urumieh-Dokhtar belt, and NE-SW trend that transects the former one and dissects magnetite bodies in some places. In this study Euler deconvolution and analytical signal methods have been used for interpretation of geophysical data. Depth of magnetic anomalies determined by Euler deconvolution clarified that magnetic bodies are located at shallow depths in the NW of the area. The trends of the detected anomalies correlate very well with the general trend of the Urumieh-Dokhtar belt. This can be used as an exploration tool for magnetic anomalies in the area and likely in other parts of the Central Urumieh-Dokhtar belt. Based on magnetic anomalies 15 diamond bore holes were drilled at the NW part of the region which cut the ore bodies at predicted levels with average ore assay of 39 percent total iron.

The relationship between surface and ground waters and their impact on each other is very important. The aim of this study was to determine the exchange of water between River jaban and Damavand aquifer. Invention Permeate, measuring the water exchange between river and aquifer was built and is being used in this study for the first time. Invention permeate was the ability of measureing the actual rate of infiltration from the river bed. This device can be used on a local scale and rivers which have low flow. Four stations to measuring the infilteration rate from the bed jaban River. Among station, station 1, in the upstream,has the lowest infiltration rate which it could be attributed to te loe permeat of shale and dense limestone below the river bed. Station 3 has the largest water infilteration water due to the high depth to water table. The resolts show that the discharge of jaban river to the aquifer is about 495 L/S .

Abstract The Gurpi Formation at Anaran Anticline in SE of Lurestan province.consists of 269.5 meters of marl with intercalation of limy marl; two formal members of Seymareh limestone and Emam-Hasan argillaceous limestone are also exposed. Studies reveal presence of 70 species belonging to 38 genera of calcareous nannofossils based on which 8 global biozones were differentiated. Consequently, the Gurpi Formation was attributed to middle Campanian through Paleocene. There is a distinct hiatus in Cretaceous-Paleogene boundary based on paleontological evidence, as deduced from the absence of nannofossil biozones NP1-NP4. It seems that the reactivation of Anaran linement as paleohigh caused facies changes and hiatus in Gurpi Formation in SE of Lurestan province.
