The possibilities of paleovalleys mapping using airborne geophysical complex

Advanced airborne geophysical surveys are a key stage in the process of transition from initial searches to the stage of detailed search. Their main task is to reasonably identify local promising areas within large-scale ground geological and geophysical work and subsequent well drilling will be carried out. Examples of such work are given in Rwanda (Central Africa), the Trans-Baikal region and Kamchatka (Russia). The obtained results make it possible to significantly minimize the volume and timing of subsequent well drilling.
