Summary:
Resistivity is a well-known method to detect rock resistance value in the subsurface. Its ability to penetrate deep into rock mass have been utilized in various field. In this study, resistivity tomography survey was conducted to identify the present of slime layer in ex-tin mining area which conducted at Kampar, Perak, Malaysia. Slime was a residual material mostly comprise sandy and clayey material. Slime was consider as weak material and can cause problems especially ground settlement. A total of five resistivity survey lines was carried out to cover entire proposed area (Figure 1). Geologically, the study area is underlain by sedimentary and metamorphic rocks which is part of Kinta Formation. Resistivity interpretation shown four different anomalies which are soft layer, compact layer (soil), slime and rock boulder. The present of slime material is deposited 25m below surface.
