【 摘 要 】

Magnetic susceptibility and morphology of magnetic minerals have been explored to some samples from the different environment near the vicinity of human's living, such as hot spring, apple plantation, paddy plantation, and reservoir. Magnetic susceptibility ranged from - 0.0009 × 10-6m3/kg (Peat in central Borneo) to 98.27 × 10-6m3/kg (Polluted Soil in Jalan Sukarno Hatta Malang). The grain size of magnetic mineral not more than that of 300 μm. Data analysis informs us that each environment where the magnetic minerals were deposited, influenced the two physical properties both of magnetic susceptibility and morphology of magnetic minerals. Regarding the environment process, magnetic susceptibility depends upon the grain size beside the kinds of magnetic minerals. So, it can be concluded that in every environment, the magnetic minerals have specific properties including magnetic susceptibility and the morphology of magnetic minerals.
