WebbThe rock layers on the top seem to form a valley but we can tell that Unit I (dark blue) on one side is the same as the Unit I (dark blue) on the other side. There is missing rock in between and a displacement caused by deformation. Cross-cutting relationships also helps us to understand the timing of events. WebbThe rock layers in an anticlinal trap were originally laid down horizontally and then earth movement caused it to fold into an arch-like shape called an anticline. This type of structure is visible on a seismic section, but, as seismic sections are normally ‘time sections’, the actual structure may be obscured by velocity changes above the anticline.
