The regularities of the internal structure of salt uplifts have not been studied enough at present. Analysis of the shape of the cavities obtained by sonar in the cavities blurred in the Mozyr dome in Belarus shows that their walls in some cases have a rectilinear shape, and the shape of the cavity in horizontal sections looks like a polygon. The experience of previous studies suggests that the appearance of rectilinear walls is associated not only with the presence of insoluble interlayers, but also with the preparation of crack systems. The relative location of fractures and cavities suggests the stress field that created them. The conducted experiments on the dissolution of salt dams confirm the great role of fractures in the formation of the relief of salt walls.

According to drilling data, the internal structure of the Mozyr salt cryptodiapir has been reconstructed, the main elements of which are strongly compressed folds with radially arranged layers on the wings, complicating domes and inter-dome depressions, flexures. A high degree of interrelation between the modern relief and the cryptodiapir roof buried at a depth of several hundred meters has been established. It is explained by the continued mobility of salts at the present stage. This feature allows us to supplement the structural and geological data with the results of morphostructural analysis of the relief and to identify certain elements of order in the structure of the Mozyr dome.
