a Interpreted seismic section Inline 200, passing through the middle part of the study area and running NE-SW direction (Fig. 1). This section shows two cross normal step faults in the SW (dipping towards the NE) and another cross fault in the NE (dipping towards SW) in the form of graben. Like Crossline 315, it also shows the two depositional sequences and their bounding sequence boundaries (DSB2 and DSB3), while the lower sequence boundary (DSB1) is also not recorded due to poor processing. b Geologic interpretation of the seismic section Inline 200 shows the different lithologic facies of the Miocene units of the two depositional sequences. This Inline denotes also the lithofacies changes of the post-Zeit Formation from mainly sandstones and limestones at the SW to mainly sandstones, limestones and calcareous shales at the NE (for legend see Fig. 5)
