bouin- miandasht granitoid pluton (bmgp), which outcropped to the north of bouin-miandasht- aligoudarz road, was emplaced into low to medium grade of triassic to early jurassic metapelitic rocks of sanandaj-sirjan structural zone. in this study we do provide the first investigations of bmgp by means of anisotropy of magnetic susceptibility (ams). most km values for the main felsic compositions ...

The study area is located in northwest of Isfahan, 25 km northwest of Daran. Buin-Miandasht intrusive rocks consist of granite and granodiorite. Based on geochemical diagrams, these granitoids are I -type calc-alkaline and evolved in volcanic arc environments. The Buin-Miandasht intruded into the metamorphic basement (Paleozoic?) and a small skarn and hornfels occurred along its contact. Based ...

Understanding the quality of groundwater resources, which are the largest available freshwater reservoir, is one of the needs in planning and developing water resources. The purpose of this research was to study the quality changes of groundwater resources in the upstream aquifers of Zayandehrood Dam (1995-2016) and to evaluate water quality in terms of drinking and agricultural consumption and...

Many endangered species are distributed in narrow geographic ranges, often at severe risk of extinction. Ecological niche modeling can be used to identify suitable areas, which surveyed detect additional populations. We combined remotely sensed data (Normalized Difference Vegetation Index) and field sampling increase distributional knowledge the improve understanding its conservation status. id...

Wind erosion is important in areas with less than 150 mm of rainfall Measuring the extent and severity of wind erosion in many countries, including Iran, there is no station to measure wind erosion sediments and so the deposition estimation methods rely on empirical models so that in many cases there are measurement errors. With estimates wind and water erosion and deposition potential compared...

Introduction Water resources are maybe the most important and the most necessary available resource for human and agriculture section. Agriculture section with almost 11 percent of gross domestic production, 23 percent of employment, and more than 80 percent of feeding the people of the country has a vital role in Iran's economy. Water as the most important factor in agriculture section, has...

Noghan granitoid intrusion is located at the NW of Boin- Miandasht and lies in the Sanandaj-Sirjan structural zone (SSZ). Based on field evidence and petrographic studies, the pluton is considered as two-mica granite that has been strongly affected by deformation and shows a good mylonitic foliation study area. The main minerals in the pluton are quartz, alkali feldspar (microcline and perthite...
