Abstract

The article presents the results of detailed geological and geophysical engineering work on the Kerch-Taman shelf. These works were carried out in order to identify potentially hazardous for engineering construction areas (for example, fault zones, local gas accumulations, etc.). The paper discusses methods for the selection of such sites, based on the analysis and joint interpretation of seismic materials and materials of marine magnetic surveys. A high degree of spatial coincidence of the areas identified by these independent methods was noted, which significantly increases the degree of reliability of their allocation. A number of geological section elements unfavorable for engineering construction have been detected and identified. The analysis of residual magnetic anomalies and their confinement to areas of discontinuous disturbances is considered in detail.
