 ABSTRACT

Subsurface mapping provides valuable information about the nature, tectonic and extraterrestrial events on earth. In order to explore the uppermost crust in Bukit Bunuh, magnetic survey was conducted using Geometric G-856 Proton Precision Magnetometer with minimum of 250m stations interval and base station reading taken every 10 minutes. Data reduction was done to produce magnetic residual map using Surfer 8. The survey area is generally divided into 2 main zones, positive and negative anomaly. Negatives anomaly showed geophysical contrast due to changes of subsurface structure. Two areas of negative anomaly were identified to be potential post meteorite impact zone.

Keywords: Bukit Bunuh, magnetic, residual, anomaly.
