Abstract : The translation discusses at length, and shows with graphs and charts, the comparison of results of the aeromagnetic survey with drilling data. It is indicated that aeromagnetic investigations are effective in determining the material composition of rocks of the Paleozoic basement in a geologically closed area. The conclusions drawn from this work are as indicated: (1) Determination of the basement rocks should be carried out on the basis of physical properties of rocks and peculiarities of the anomalous magnetic field above open areas, where known Paleozoic complexes of rocks are exposed on the surface. (2) While dividing the Paleozoic basement rocks in terms of material composition it is necessary to consider the depth of occurrence of magnetic rocks which cause T anomalies. (3) On a geologically closed area an analysis of the anomalous magnetic field from the point of view of determining the composition of the Paleozoic basement should be carried out in combination with the gravimetric data.
