Upper Cretaceous, Aqra-.An upward fold is called an anticline, while a downward fold is called a syncline. In many areas it’s common to find a series of anticlines and synclines (as in Figure 12.5), although some sequences of rocks are folded into a single anticline or syncline. Of particular note is the overprinting of the azimuthal anisotropy in the post-Eocene overburden by the pre-Turonian (Cretaceous) faulted anticline. This is consistent with an interpretation of late uplift of this deep structure and the consequent extension of the overburden in a direction orthogonal to the structural axis. ….
