Lithology and Thickness

The deposits of the suite are represented by pale, brownish-gray, light-brown loess with six paleosols of pale-light-gray and one dark-brown to black. On the plain and in the foothills, the number of paleosols decreases to two or three, and only two pedocomplexes are clearly distinguished. In the lower part of the suite, small (2-3 cm) carbonate concretions of the "crane" type, white in color, are abundant. Thickness from 20 to 50 m and more.

Previously (Mikulin et al., 1982), the suite was distinguished as the Pskent layers. The suite encompasses two complexes - the Golodnostepsky and Syrdarya.
