Syncline In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline.

The Cherahil anticline structure shows, in the subsurface, a thrust fold developed over the Cherahil thrust (Fig. 8.42). The Middle–Late Eocene horizons are presumably thinner toward the top of the Cherahil fold which indicates that this compressional structure occurred during the Middle–Late Eocene.

In structural geology, an anticline is a fold that is convex up and has its oldest beds at its core. The term is not to be confused with antiform , which is a purely descriptive term for any fold that is convex up.

A rollover anticline is a syn-depositional structure developed within the downthrown block (hanging wall) of large listric normal faults. Such faults are typically regional in nature and develop as a response to extensional collapse of a passive continental margin (i.e. Niger Delta, Mississippi Delta). Their main feature is that they flatten ... 24 Agu 2016 ...
