In this work we investigate thoroughly the mecha-
nisms that generate salt diapirs in brittle rocks
[Poliakov et al., 1996] using the fully dynamic model
of natural materials with internal structure. The over-

burden and salt are represented by sandstone and
salt blocks, capable to be separated or crushed
under exterior load. In the 2D model we equate the

Thus set are a brittle-elastic medium, which one
frequently use at physical simulation in this field. In
such model density contrast between salt and brittle
overburden leads to the salt diapir generation. By
additional causes can serve small regional sedi-
ments tensions, their erosion, local basement sub-
sidence along fault. As a result of computer 2D-
simulation and comparison with geologic datas on
salt tectonic of the Dnieper-Donets Rift basin (Ukrai-
ne) is established, that buoyancy forces are capable
to drive diapirs of salt into brittle overburdens.

Fig. 1 shows the result of computer 2D-simula-
tion of salt diapir growing. Fig. 2. shows the com-
parison of salt diapir growing in case of different thick-
ness of sediment overburden. Fig. 3. shows the
comparison of salt diapir growing with and without
erosion.
