In the results of investigations, fulfilled with ELFP profiling method at joint application with VLF profiling method, on Vuoksa massif is discovered a new zone with geoelectric features, similar for well studied part of the massif with apatite. The received materials gives the foundation for continuation of the works on the apatite perspective estimation of Vuoksa massif. The materials of the article shows high informativity of ELFP method on industrial frequency 50 Hz at search and mapping investigation in the transient zone between Baltic shield and Russian platform.
