ABSTRACT. This paper presents the magnetic properties, mineralogy and heavy metals content of
soil and concretion samples taken from areas of Kundasang (K-S1 and K-C1) and Ranau (R-S2 and
R-C2), Sabah. Samples were extracted by a U-formed magnet with strength of 780 Gauss to isolate
the magnetic particles and later characterized using Vibrating Sample Magnetometer (VSM), X-Ray
Diffraction (XRD), and Atomic Absorption Spectrometer (AAS) techniques.
KEYWORDS: concretion, pseudo-single domain, hematite, heavy metals.
