Magnetic signal approach to the interpretation of meteorite impact crater at Bukit Bunuh

Bukit Bunuh is situated in Lenggong Valley, north of Kota Tampan, Perak state, Malaysia. The meteor impact crater is also known as a small impact crater and has an approximately circular depression on the surface of the Earth. This paper presents the magnetic map for the Bukit Bunuh impact structure presented in the form of a contouring image. To detect the impact structure and its structural attribute, a series of magnetic profiles were measure across the suspected area. Magnetic measurement was conducted using Geometric G-856 Proton Precision magnetometers to measure the earth's total magnetic field and the data was processed using Surfer8 software. The analytic signal map was produced showing low magnetic value indicating that the crater is filled with sediments, surrounded by high magnetic value, which interpreted as a rebounds zone. Crater dimensions are estimated at about 5 km with central uplift at the Bukit Bunuh area.
