Abstract
The eastern Tunisian Atlas shows major subsurface faults: the Kairouan-Sousse Fault (FKS), to the north, and the El Hdadja fault (FEH), to the south. The FKS is an inherited structural trend active since Late Cretaceous times. This fault is an eastern splay of the Cherichira-Labeid fault. It separates a large northern diapiric structure (Ktifa Diapir) from a subsident domain (the Kairouan-El Hdadja rim-syncline), with a pull-apart configuration to the south. The latter area, which appears to be an inherited weakness zone at the range border, has recorded a series of tectonic events that characterizes the Alpine structural development in Tunisia.
