In the provided legend two sets of sedimentary rocks are found. The upper set which includes dolomite and conglomerates unconformably overlies a lower set of shale, marl, sandstone and limestone as shown in the legend. A part of the outcrop of the lower surface of the marl bed appears in the eastern flank of a symmetrical fold. The axis of this fold represented on the map by the line A-A. The lower surface of the dolomite bed crops out at point B, where the direction and amount of two apparent dips are recorded. The line F-F on the map represents a major fault in the area which has dropped all the northern part 100 m relative to the southern part.

It is required to: –

1- Draw and color the outcrops for all the beds.

2- Calculate the true thickness for the sandstone bed.

3- Describe in details all geological structures in the map.

4- Draw a cross section along the line X-Y. Use vertical scale 1cm = 100 m and compute the vertical exaggeration.

5- Utilizing the stratigraphic succession and geological structures, explain whether there is any oil potentiality in the mapped area. Mark the best location on the map to drill an exploratory well by a capital letter (W)
