Аннотация
We review the results of different-scale airborne geophysical survey performed in the territory of Rwanda. Such parameters as the total magnetic field, electromagnetic sounding data in time and frequency domain, as well as data from a gamma-ray spectrometer with a total scintillator volume of 32 liters were continuously recorded during the flight. Automated execution of flight tasks allowed to exclude an operator from the surveying process. It took only 6 months of field works to perform the survey. The total workscope amounted to 57,718 line km. Based on the results of map interpretation we selected prospective sites for further study. Detailed airborne survey was performed for 5 sites, and ground geological and geophysical survey was performed for 3 sites. Based on the detailed survey results we selected new local objects associated with quartz-magnetite veined mineralization, dyke bodies, and mafic rock intrusions. Multiple pegmatite intrusions were identified. The information about magnetic, electrical and radiometric characteristics of rocks allowed to reliably classify the identified objects.
