A magnetic investigation along a NE–SW transect of the Yasouj Plain, southwestern Iran

摘要: The magnetic susceptibility (χ) of soils varies with the slope position due to some factors such as texture, drainage class, and land use. Limited information is available about properties semi arid regions southwestern Iran. This study attempts link χ Fe oxides landforms, soil characteristics, use (paddy dryland soils) on same parent materials. Ten representative pedons were taken along a NE–SW transect in different physiographic units Yasouj Plain. results indicated that determined mainly by topography In most pedons, highest concentrations poorly crystalline (Feo) observed top types Aquic condition paddy seems main cause for significant decrease amount Fed studied soils. Maximum concentration pedogenic (Fed) was noticed more stable landforms non-aquic moisture regime. Paddy exhibited higher Feo/...
