ABSTRACT
This chapter provides a simple example of how a number of 2-D sections can help the interpreter in deducing the most likely evolution scenario. The complex evolution of salt structures makes a comprehensive understanding of the 3-D flow of salt through time difficult. For an exponential depth-porosity relation it is important to note that the deeper the base of the sediments, the more sensitive is the calculated surface porosity to variations in the base sediment porosity. The sediments are exposed to lateral stress by the growing overhang and are simultaneously collapsing into the enlarged rim syncline. The Tertiary sediments show some thickening towards the salt and indicate the development of tertiary rim synclines. A larger overhang was created on the NNW-side, but, through Late Cretaceous and Tertiary times, the overhang development on the SSE-side resulted in an almost symmetric present-day salt diapir.
