UAV-based geophysics for geological mapping, mineral exploration, and nearsurface investigations

Abstract. The article reviews the current capabilities of unmanned aerial vehicle (UAV-based) geophysical methods for solving a broad spectrum of geological tasks, ranging from regional-scale mapping to shallow-depth investigations. The primary focus is on the authors’ novel UAV-based electromagnetic surveying technology aimed at exploring large areas (covering several hundred square kilometers) at depths of 500–800 meters. The authors concisely describe the methodology and equipment used. Case studies from multiple sites illustrate the practical application of the UAV-based geophysical system. The results demonstrate the potential of the proposed UAV-based technologies. Both international and Russian research efforts facilitate prospects for further development.
