             recorded in the stratigraphy, which is well known from over 10,000 boreholes
             and  extensive  seismic reflection  profiling  (the main  stratigraphic  horizons
             being also good reflectors).
               Trusheim (1957, 1960) examined the growth  of  one salt dome, or stock.
             The mobilization of  the salt and the formation of a salt pillow is reflected in
             the development of  the Keuper (Fig. 15-9). During the early Cretaceous trans-
             gression, the salt pillow became a true penetrative diapir, and what Trusheim
             called the secondary rim  syncline developed. By the end of the Tertiary, the
             salt  pillow  had  been  virtually  replaced  by a mature  salt dome.  Sannemann
