STRUCTURE OF THE EARTH'S CRUST BY GEOPHYSICAL DATA (STROENIE ZEMNOI KORY PO GEOFIZICHESKIM DANNYM),
Abstract : The goal of the present work is the finding of general regularities of the crustal structure by means of comparisons of seismic data with gravity anomalies and contour intervals. The comparison of the gravimetric and seismic data was performed by two methods; graphic method and by the analysis of velocity columns of the earth's crust. There is a chapter in this work devoted to these two methods. Seismic investigations of the crustal structure in sea and ocean regions were carried out by the methods of refracted and reflected waves. Only the general features of these investigations is taken into consideration. The earth's crust is subdivided into continental and oceanic. A chapter is devoted to the study of the structural differences. All the results obtained during this investigation are the summary of the first and most general phase of works for the study of the abyssal crustal structure and the connection of deepseated and surface structures. In further study of this problem, it will be important to include a more detailed comparison of geophysical data with tectonic data and their multiple interpretation in order to find out necessary conditions of the crustal structural development.
