Geophysics

The authors pursued their goal to develop a system of approaches in the organization of unmanned magnetometer survey, implemented for structural and geological mapping. The data for the research were collected within the project in the Neryungrinsky district of Yakutia. Based on the obtained materials, the authors carried out the analysis, modified the office analysis of magnetometry data as well as created a physical and geological model of the investigated area.

Given the pandemic environment, not every subsoil user is ready to organize large-scale on-the-ground geophysical works. This is due to both the uncertainty in the future cost of resources and the risk of disruption due to COVID-19. At the same time, we would like to cover large areas with surveys, so as to obtain the data and plan the works for the next field season. One solution is to apply geophysical survey methods using UAVs (Unmanned Aerial Vehicles).

The paper presents the results of high-precision magnetic surveys by a quantum magnetometer using an unmanned aerial vehicle (UAV). The object of research was an area of 10 hectares at the archaeological site of Novaya Kurya in Western Siberia. Magnetic anomalies caused by ancient mounds with amplitude of up to 5 - 10 nT were revealed. The received information makes it possible to plan a strategy for archaeological study of this monument at a qualitatively different level. Same technology can be applied at any other archeological site.
