D. Aeolian deflationary-accumulative relief (sandy slightly undulating plain). This relief is located on different surfaces of the denudation -accumulation cycle (Karnab, Sukaita, Amudarya) and its formation is mainly associated with wind activity. The sandy slightly undulating plain occupies a wide strip located between the proluvial undulating plain and the proluvial slightly undulating plain in the central and northwestern parts of the study area. The waviness is due to the presence of cluster sands, sand mounds, dunes and ridges with relative elevations from 1-3m to 6-8 meters. Bush sands, up to 0.5-1.0 m high, are located in the southeastern part of the plain. Along with cluster sands, there are accumulations of sandy material in the form of a continuous mantle with a horizontal occurrence. Hilly sands with individual small dunes, up to 2 m high, are developed in the central and northwestern parts of the plain. Between hillocks and barkhans there are often blowing hollows 1-3 m deep. Ridge-hilly sands up to 6-8 m high with blowing hollows 3-5 m deep are developed in the southwestern part of the plain.
Dune sands 2-3 m high are found in separate areas in the southeastern and central parts of the sandy plain. The eolian sands of the Amudarya complex are underlain everywhere by deposits of the Sukaita and undivided Karnab and Shorkuduk complexes.
Deposits of the Sukaitinsky complex are represented by sandy loams, loams and gravel-pebble deposits in the overflow with uneven-grained sand, with a total thickness of 15-25m. The deposits of the undivided Karnab complex are presented from above by gravel-pebble deposits interspersed with sand, with interlayers of sandy loam and gravelstone. Below are dense sandy loams and loams. The total thickness of the deposits of the inseparable Karnab and Shorkuduk complexes within this area is 25-30 m. Clays and siltstones of the Guzar suite ( N ₂ ^gz ).
Thus, the eolian deposits were formed as a result of the development of both Pliocene bedrocks (in the southern part of the region), and alluvium and proluvium of the deposits of the Karnab and Sukaita complexes. Accumulations of these sediments form cluster sands, sand mounds, ridges and, rarely, dunes, consisting of uniform fine-grained sands of brownish and grayish-yellow color, with a total thickness of 0.5 to 5 m. Within the sandy plain, depressions are often found, the bottom of which is sprinkled with small pebbles, fragments of fauna and gypsum crystals formed as a result of blowing sand from parent rocks.
In conclusion, we can conclude that within the study area, 4 levels of the denudation-accumulation cycle are established for the Quaternary period, which decrease in steps from high hypsometric marks to low ones.
