In this study, the subsurface structures of the northern Kontum massif were determined using aeromagnetic data for the first time. The results showed that the area is dominated by E-W and ENE-WSW trending lineaments, with depths ranging from 50 to 550 m. The presence of probable granitic intrusions was also observed. This magnetic interpretation provides valuable insights into the structural features of the northern Kontum massif.
The Kontum massif plays a key role in the tectonic development of the central Vietnam terrane. However, most of the northern part of the Kontum massif is covered by sediments. In this paper, we determine for the first time the subsurface structures of the area using aeromagnetic data. We have evaluated the effectiveness of six enhancement techniques on a synthetic model before applying these techniques to real aeromagnetic data of the study area. The results obtained from these techniques show that the study area is dominated by E-W and ENE-WSW trending lineaments and the depths of most of these structures range from 50 to 550 m. The findings also show some probable granitic intrusions in the study area. Our study provides the first magnetic interpretation for a better understanding of the structural features of the northern Kontum massif.
