- Abstract
Characterisation of subsurface soil at Guar Kepah, Kedah Tua (Malaysia) was carried out using electrical resistivity tomography for shallow archaeological investigation. Apparent resistivity data were acquired using ten profiles and one additional profile at the edge of an already excavated portion of the study area for correlation of soil types. Subsurface resistivity values obtained in the study area led to four distinct soil types. The first (very-low resistivity of < 20 Ωm) was wet clay; the second (low resistivity of 20-100 Ωm) was sandy clay; the third (intermediate resistivity of 100-200 Ωm) consisted of shell flakes mixed with sandy clay; and sand (high resistivity of > 200 Ωm) was confirmed in the fourth type. A verylow resistivity (< 20 Ωm) anomaly was identified in the resistivity tomograms of the ten profiles, interpreted as wet clay materials associated with archaeological remains.
