A studies using the resistivity method have been carried out to determine the potential of iron sand in Ulakan Tapakis West Sumatra. This study aims to establish the potential 3D modelling of iron sand. Wenner array is used to determine location of anomalies by taking 5 sections which has 180 meter length. The distance of the electrode used is 3.9 meters. Generally, Ulakan Tapakis has 3 main components of alluvial deposits, namely a layer of top sand (upper sand), middle sand, and a layer of iron sand which is divided into 2 layers, namely the bottom sand and the iron sand layer which has a resistivity value ranging from 9.53 -14135 ωm. These layers have different resistivity values depending on the constituent material. The existance of iron sand is located at depths of 0-6 meter below sea surface, with range of resistivity is 9.53-1000 ωm. © Published under licence by IOP Publishing Ltd.
