Magnetic susceptibility (χ) measurements are widely used to study soil-forming processes. This study was conducted to determine the role of lithology, geomorphology, and soil processes in soil magnetic properties in an arid region of Southern Iran. For this purpose, ten representative pedons (in 3 zones, based on lithology) on different geomorphic positions, were studied. In addition, 82 topsoil samples were collected to investigate spatial distribution maps using GIS software. The χ_lf range of soils was from 74 to 1495 × 10⁻⁸ m³ kg⁻¹. The average amounts of χ_lf in the soils of the three zones were 1082, 245, and 153 × 10⁻⁸ m³ kg⁻¹, respectively. While the highest value of χ_lf of the soils of zone 1 (with metamorphic parent material), was observed at the bottom-profile, the highest value of χ_lf of the other zones (with fine-grained evaporates and coarse-grained sandstone parent materials, respectively) was observed at the profile-top. Spatial distribution of χ_lf and total Fe values exhibited the highest amount in the soils of zone 1, which were attributed to adjacent iron-rich metamorphic formations. Higher values of χ_fd were observed in the soils of zones 2 and 3, suggesting a higher proportion of pedogenic ultrafine grains. The maximum value of pedogenic susceptibility (χ_p) was observed in the soils of zones 2 and 3, indicating higher proportions of pedogenic secondary iron oxides; however, the negative value of χ_p in the soils of zone 1, support this hypothesis that most of the χ_lf signal is carried by bedrock magnetic minerals.

磁化率（χ）测量被广泛用于研究土壤形成过程。进行这项研究是为了确定岩性，地貌和土壤过程在伊朗南部干旱地区的土壤磁特性中的作用。为此，研究了十个具有代表性的脚架（在3个区域，基于岩性）在不同的地貌位置。此外，使用GIS软件收集了82个表土样品以调查空间分布图。该χ _LF土壤范围为74至1495×10 ^-8米³ kg的^-1。三个区域的土壤中平均_χlf分别为1082、245和153×10 ^-8 m ³ kg ^-1， 分别。而χ的最高值_LF区1的土壤（与变质母材），在底部轮廓，χ的最高值，观察到_LF其它区的（具有细粒度蒸发和粗粒度砂岩父分别在顶部观察到材料。_χlf和总Fe值的空间分布在1区土壤中表现出最高含量，这归因于邻近的富铁变质地层。χ的值越高，_FD中区2和3的土壤中观察到，这表明成土的超细晶粒的比例较高。成土磁化率（χ的最大值_p）在2区和3区的土壤中观察到，表明成岩性次生铁氧化物的比例更高; 然而，χ的负值_p区1中的土壤，支持这一假设，即大部分的χ的_LF信号由基岩磁性矿物进行。
