The role of geological survey in the functioning of complex urban natural-technogenic system is constantly increasing.

Continuous growth of territories and population of large and major cities puts forward more and more complex tasks for urban planners. Among them are particularly acute the following: strict economy of scarce urban land; sharp improvement of urban transport; increasing the safety of urban traffic; ensuring the reconstruction of historically established areas and city centers, preservation of cultural monuments and all the supporting capital development and natural environment.

In recent years, in connection with the tasks of practical development of the shelf is becoming more and more massive construction not only in shallow water, but also at relatively great depths in the sea ...

The question of the relationship of manifestations of creep of clayey rocks with the conditions of formation of their physical and mechanical properties and the nature of the nature of structural bonds remains poorly studied. The most fully investigated in this respect is only the Late Glacial banded sediments of Leningrad.

Among late and postglacial deposits in the countries of Scandinavia, in some areas of Canada and the USA, blue soft-plastic and mobile floating clays are well known. Their properties are similar to the clays of the coastal belt of the White Sea and the basins of the lower reaches of rivers flowing into it (Kem, Vyg, etc.). Similar deposits are also known on the Kola Peninsula.
