Abstract
The article examines the geocrylogical studies of the southern part of Western Yakutia, the territory of which is adjacent to the area of well-developed diamond deposits of Yakutia. The geocrylogical conditions of diamond deposits have been studied in detail. In most fields, the presence of a deep cryolithozone with a non-stationary temperature field was revealed. Cryolithozone thickness drastically decreases in the southern direction and passes into island and intermittent cryolithozone. In this regard, the transition zone requires additional geocrylogical study. In addition, there is currently intensive development of oil and gas fields in the south of Western Yakutia. Most of the hydrocarbon transportation and processing facilities are located at the territory representing the zone of island and intermittent spread of permafrost rocks. While the main task of engineering and geocryological research in the continuous permafrost zone is to study the morphology and temperature of cryolithozone, in the areas under study the problem of identifying ‘islands’ of permafrost rocks and assessing their cryogenic structure becomes particularly relevant.
