Kur depression covering a considerable part of the territory of Aazerbaijan an is a standard for atudy of buried palaeorelief of depressed territories. The huge thickness (about 15 km) of sedimente here buried in themselves many atoried heterogenous and heterochronoc palaeorelief. In order to reestablish it there are great numbers of data of different kinds of wells and geophysi cal materials allowing to use successfully the methods of analysis of facies and thickness of lower pliocenepleistocene sedoments (prepliocene revelations ns are isolated) for reestablishing the buried ry in given interval. There is no need to speak about the obviousness of the method actualism. The logical construction in the work of reestablishment of palaeoreliet is simply necessary, without them it is impossible to use any methods. The palaeomorphological investigations related to Kur depression allowing to reestablish enough in detail the pliocenepleistocene relief of basins have been carried out by us. There investigations at the same time beared an applied significance, as the entrails of this basin are rich with the fields of oil, gas, underground fresh waters, building materials, etc.

The guintessence of there investigations is the maps of Kur depression complied by us where it is shown the genetic types of relief both in land and in the bottom of sea, separate forms of relief, lithology of rocks, age,boundaries of sea basins and others. Compiled stagely, they illustrate the origin and development of separate morphstructures, beginning of appearance and development of mudvolcanism, rupturing tectonics,etc.

These maps have also a great applied significance. So, for example,the areas and forms of relief (bed and delta of rivers, alluvial cone, bars, spits, etc.) given there are perspective for searching there the oil, gas, underground fresh waters,building materials,etc.
