Abstract
In this study we have analized magnetic properties of soils from landslide potential area. Top soil and four soil cores from Pasir Ipis as study area were taken as samples. All samples measured by rock magnetism method, magnetic susceptibility, to describe the characteristic of the physical property of samples. Magnetic susceptibility values of top soil samples are ranging from 193 × 10-8 m3/kg to 545 × 10-8 m3/kg, whereas for soil cores the magnetic susceptibility values range from 245 × 10-8 m3/kg to 674 × 10-8 m3/kg. It implies that the soil samples are dominated by ferrimagnetic minerals. Relative difference of magnetic susceptibility values measured at two frequencies or χfd f (%) for all samples range from 2 to 10%, indicating that the samples contain a mixture of ultrafine superparamagnetic grains and non superparamagnetic grains.
