CONCERNING THE POSITION OF HYDROCARBON NATURAL MIGRATION IN THE GEOMORPHOLOGICAL ZONING OF THE LAKE BAIKAL BOTTOM

An up-to-date geomorphological diagram of the bottom of Lake Baikal was compiled. Geological and geomorphological studies showed that denudation-tectonic processes are the leading topography-forming factor. The great influence of geomorphological zoning on the distribution of bottom manifestations of gas crystalline hydrates was found. Three types of hydrate manifestations were identified depending on the geomorphological position.
Keywords: Baikal, geomorphology, gas crystalline hydrates.
