The article discusses current problems of determining the main features of soil formation on self-expanding tank wastes. For this purpose, tasks were performed to determine morphological and other properties of the soil. It is established that the main pedogenic transformations occur in the root zone. Transition horizons are difficult to determine during morphological study. This is explained, on the one hand, by the weak development of the processes, and on the other, by the high content of carbonaceous particles in the rocks that form the wastes. The distribution curve of the total organic carbon along the profile is of concave character with a sharp drop with depth (accumulative distribution type). As a result of the illimerization, the minimum content of the fraction of physical clay moves to deeper layers in soils of the subordinate elements of the landscape. At the same time, the content of the sludge fraction increases, which may indicate processes of not only physical, but also of pedogenic disintegration of the rocks composing the waste.
