Abstract:The cryolithic zone is the designation for a zone of the Earth's crust having a sub-freezing point temperature; the frozen rocks are rocks which contain ice; the cold (frost) rocks are rocks whose temperature is below zero but which do not contain ice. It is reliably known that a cryolithic zone is extensively developed below the bottom of the Arctic Ocean and its fringe seas. However, the geocryological study of the sea bottom is extremely deficient. Reports about the distribution, properties and developmental principles of rocks of the sea bottom cryolithic zone have already long been necessary to support navigation through the northern maritime routes and for the construction of ports. Their requirement has sharply increased in connection with the initiated recovery of natural resources of the arctic shelf. The enormous practical significance, poorly studied nature of and poor access to the subsea cryolithic zone render its investigation one of the most interesting and pressing problems of modern cold research.
