Abstract The use of percent frequency-dependent magnetic susceptibility (χfd%) is well-established for detecting superparamagnetic (SP) components in fine-grained soils and sediments. This study employs χfd% as a direct indicator pedogenetic processes from the Moroccan Rif region. Three soil transects (T1, T2, T3), each comprising four cores with depths reaching 100 to 120 cm, were sampled distinct lithological formations within an area subject moderate intense erosion. A total 272 samples collected analyzed using MS2 Bartington Instruments, providing values calculate identify ultrafine ferrimagnetic minerals (SP, < 0.03 μm). In Quaternary fluvial terraces (T1) soils, approximately 60% indicate mixture SP, multidomain (MD), Single Stable Domain (SSD) grains, while 30% contained coarser MD grains. Only 10% exhibit predominantly Soils on marly substrates (T2) showed 90% combination MD, SSD, just had SP contrast, Villafranchian sandy deposits displayed exceeding over 50% samples, indicating that almost all iron consist Physico-chemical analyses profiles T1, T3 reveal characteristics, including variations clay content, organic matter, nutrient levels, proportions free iron. These results are important understanding evolution pedogenesis, T1 showing advanced development marked by high mineral iron, clay, matter content. profile T2 reflects weak stage, influencing availability contributing overall dynamics respective profiles. this suggest susceptibilities these primarily originate sources, revealing significantly pedogenesis compared soils. findings align previous research erosion degradation region, demonstrating developed more degraded less stable than those substrates. underscores utility rapid effective initial assessment gauging degree pedogenesis.
