Why do we not see diapirs in the upper part of a gravity-driven décollement setting such as shown in Figure 19.24?
What will be an ideal response?
Answer: There is no or too little loading that can drive diapirism. The load increases down dip due to gravity and the tapering of the sedimentary wedge overlying the salt.
