Application of Geoelectrical Resisivity Method for Iron Sand Exploration in Ulakan Tapakis Padang Pariaman

Abstract There is no doubt about the presence of iron sand around west coast West Sumatra. Several studies have been carried out, but in Ulakan Tapakis area still under observation, and investigation its potential distribution. One methods that can provide models subsurface descriptions using goelectrical resistivity method. The geoelectrical application was used Wenner-Schlumberger array into 4 section. section designed perpendicular to beach with a length 47 meters for short lines 470 long line, distance between sections 65 meters. results obtained form pseudosection types. Each describes distribution lithology rocks below surface. combination all gives an overview model at Tapakis. From measurements array, be found along study depth 0.7 m - 3 line 40 values ranging from 52 289 Ωm
