Abstract

The airborne magnetic+  and  gamma spectrometric  surveys have been applied in Vietnam for basic geological survey and mineral prospecting. The effectiveness of the method has been confirmed. However, there are still some limitations. In order to improve the effectiveness of the methods, it is necessary to arrange proper density of survey grid, to equip the advanced airborne-magnetic and gamma spectrometric devices and to carry out   more ground check of the magnetic and gamma anomalies detected by the airborne survey.
