 ABSTRACT

Bukit Bunuh is situated in Lenggong valley, Perak (Malaysia) surrounded by mountainous terrain underlain by granitic formation of Bintang range. A few geophysical investigations are carried out to study the unrevealed impact crater for the area. Gravity is one of the methods applied to contour the variations of density distribution. A survey area of 128 km2 was covered using Scintrex CG5 AutoGrav and further processed using Microsoft Excel and Surfer 8. The gravity result shows the bouguer anomaly contour verified clearly the subsurface density. The occurrence of isolated positive and negative bouguer anomaly suggested the area could be a simple crater

Keywords: Bukit Bunuh, gravity, density, simple crater
