(Abstract)

The work presents a method of geophysical investigation of the complex sulphide ore explored by core drilling.
Thus, beginning with some geochemical considerations, there are stated the necessary technical elements, on which the geophysical research method proposed is based.
The geochemical dependences studied as well as the statistic data resulting from the geophysical records, are the basic elements for the plotting of the quantitative and qualitative interpretation graphs.
Furtheron, the work presents a lot of practical applications of the method through which are exemplified the soundness of the theoretical considerations as well as the economic efficiency of the method.
