Abstract:
In northern Germany there are more than 200 known salt stocks which are composed of Zechstein salt. Because of favorable geologic conditions, it was possible to reconstruct the historical development of the salt stocks with the aid of reflection seismic surveys. The development of a single salt stock appears to have started with an accumulation of salt, the so-called salt-pillow. At a later stage, the overlying strata broke, allowing the diapir to form. In northern Germany, genetic connections between salt stocks are recognizable. Some of the larger groups of salt stocks are classified as "salt stock families." Such salt stock families consist of a number of salt stocks grouped around the genetically oldest which is said to be the "mother salt stock." The rim synclines of the adjacent salt stocks become younger as their distances from the center increase.
The geological impulse causing the formation of mother salt stocks is supposed to be partly due to tectonics whereas the subsequent wave-front-like growth of the salt stock families took place in a purely halokinetic way, i.e., by the movements of salt under the influence of gravity. The absolute rate of the horizontal wave-front-like flow of the salt over large distances averages about 0.3 mm./year.
