In the present study, geochemical characteristics of sequences Gachsaran Formation, located in west Kermanshah province, Iran - Iraq border zones, were studied. order to determine concentration elements, XRF and ICP-mass techniques employed, XRD technique was used identify mineralogical composition finally, evaluation level pollution caused by these elements carried out using statistical index ...
The aim of this study is to investigate the feasibility of using waste bricks powder of Gachsaran Company in concrete. Cement is replaced by waste bricks powder in different proportions until 40 percent by weight. pozzolanic properties of bricks powder and compressive strength of concrete were investigated. The results demonstrated that the bricks powder show pozzolanic properties. Results also...
A total 7 species and 13 genera of marine gastropod assemblages are reported for the first time from the Varehh Zard section (Asmari Formation), north of Pole Dokhtar, Lorestan Basin. The section under study, the Asmari Formation, lies between the Shahbazam Formation at the base and Gachsaran Formation at the top. According to the distribution of index foraminifera, the Asmari Formation is Earl...

importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. to determine the contribution of each geological formation in sediment input of gachsaran floodwater spreading station after 12 years of flood spreading, sediment sampling was conducted in 16 points and 0-15 cm depth of the field. using dry sieve analysis, all samples were anal...
Abstract Local P-wave tomography is an efficient method to study geologically complex areas where the seismic exploration methods are not ideal for unraveling shallow crustal heterogeneity due great thickness of evaporitic deposits. Despite geological features in salt-rich DehDasht region, SW Iran, we used more than 11 000 micro-earthquake events, which have been recorded by a temporary network...
Water stress is one of the most important factors limiting the growth and yield of plants in many parts of the world. In order to evaluate the effects of water stress on some morphological, physiological and antioxidant enzyme activity traits of lentil, four lentil cultivars (i.e. Gachsaran, Kimia, Ziba and Robat) in four water deficit treatments including 25%, 50%, 75% and 100% of the field ca...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
The purpose of this study was to investigate some environmental factors of Zagros forest dieback. In this regard, raster layers of elevation, slope, aspect, hillshade, toposhape and the land formation of Zagros forests in Ilam province were prepared. The distribution map of live and dieback forest cover were also prepared, using Landsat 8 panchromatic images. Then, the percentage of dieback for...
Soils are severely damaged by acid rain; acid rain also leads to excessive dissolving of minerals and valuable nutrients in the soil, which weakens vegetation. In this study, in order to determine the interaction effect between the slope aspect and precipitation intensity relative to acid rainfall in the Aghajari and Gachsaran formations, a part of Margha and Kuhe Gach watersheds of Izeh city w...
