Ground magnetic data assessment of the geology and structural view of Bukit - Bunuh impact crater area, Malaysia

Abstract

Ground magnetic data obtained at Bukit Bunuh area was analyzed using several magnetic data (signal)-processing (magnetic derivative) techniques that include vertical derivatives, total horizontal derivatives, and analytic signal. The study was aimed at providing an insight on Bukit Bunuh geology, structures, and their patterns. The magnetic derivative anomaly maps obtained showed an enhanced high frequency signature related to the surface or sub-surface causative geological bodies. The maps showed the pattern ofemplacement ofgranitic plutons within the Bukit Bunuh crater zone. The research outcome (results) showed a clear distinction between the edges of the granitic plutonsfrom Quaternary sediments as well as the weathered overburden anomalies which were previously not known. The findings of this research were used to update the current lithological/structural map of the Bukit-Bunuh crater area of Peninsular malaysia.
