THE USE OF UAVS AND GROUND-BASED GEOPHYSICAL METHODS IN THE STUDY OF THE ANCIENT METALLURGICAL COMPLEX AT THE BARUNKHAL II SITE (WESTERN BAIKAL REGION). GEOARCHAEOLOGY AND ARCHAEOLOGICALстатья
Аннотация:Ancient iron-making complexes are in many places on the western coast of the central part of Lake Baikal. The objects are located in the folded frame of the Siberian platform, represented by deeply metamorphosed rocks of the Olkhon crystalline complex. The possibilities of terrestrial and UAV magnetic surveys and electrical resistivity tomography (ERT) are considered to optimize searches and study archaeological sites with minimizing excavating by applying. They use 3D inversions of geophysical surveys’ data to localize and estimate parameters of physical-geological models of archeological and geological near-surface objects. Comparing the modeling results on a well-known archaeological site has given a chance to estimate the effectiveness of the methods used. Inversion of magnetic fields using vector scanning and elastic net regression allows receiving a geometrical image, spatial distribution of susceptibility, and remanent of furnaces by terrestrial and UAV magnetic surveys data and distinguish object artificial and geological origins.
