Book excerpt: The results of correlation of large features of the earth crust stratification on the territory of the USSR obtained on the basis of inerpretetion of the complex of regional geophysical data with elements of pre-Neogene and post-Neogene tectonic structure are briefly discussed in the paper. It is found that the thickness of the earth crust as a whole and the thickness of basalt layer are clearly related to Neogene-Quarternary structure, and the thickness of granite layer furthermore reveals the connection with pre-Cenozoic structure and with the history of its development as well. The draft of density heterogenity with the upper mantle is discussed. Manifestation of isostasy for large territories are clearly evident. The authors insist on the fact that the processes of basification play an essential part in the development of the earth crust. (Author).
