Magnetic properties and morphology of magnetic minerals from agricultural soils were identified to evaluate their potential as proxy indicator of pollution. The study was carried out by means of magnetic susceptibility measurement in dual frequencies and scanning electron microscopy (SEM) analysis. The samples were obtained by coring process as well as topsoils samples. The results showed that the low frequency magnetic susceptibility (XLF) of samples from topsoils are in the range of 26.1-104.4 (10-8 m³/kg), whereas core samples has magnetic susceptibility of 11-172.5 (10-8 m³/kg). It infers that the samples are dominated by ferrimagnetic minerals. The relative difference of magnetic susceptibility measured at two frequencies, namely XFD(%), is less than 4% for topsoils samples. The XFD(%) value of 1-4% are often found in soils contaminated by anthropogenic sources. Core samples has XFD(%) of 0-15%. It suggests that magnetic minerals in core sampels are from pedogenic and anthropogenic sources. According to SEM analysis, magnetic minerals with spherules shape was found in sample dominated by anthropogenic source. Magnetic minerals in sample with less contaminated has hedral shape.
