ON FORMATION OF DEPRESSION-CHANNEL MIGRATION STRUCTURES
The depression-channel structures widely developed in the flat areas of sea floor and dry land are considered as a product of interaction between the global earth crust fractures of the vibra- tion-wave origin and degassing of the planet. The paper describes general peculiarities of the depression-channel structures generation and development on sea floor and dry land, the leading role of the lithified rocks fracturing and weakened zones of the overlying non-lithified rocks in the gradual transition of fracture degassing to degassing via channels, differences in subsequent epigenetic exogenous processes following the active phase of depression-channel structures formation. Revealed signs of secondary gas activation in the depression-channel structures were
