That type of fault is known as Synclinal fault.
Sycline
Syncline is a type of fold that is created when the crust bends and curves downward. It is a fold that is convex up and has its oldest beds at its core.
This geological formation is called a syncline. It is a downward fold in the rock layers where the youngest layers are in the center and the oldest are on the outside.
The opposite of a syncline is an anticline. An anticline is a fold in rock layers that arches upward, whereas a syncline is a fold that bends downward.
A downward fold in a rock is called a syncline. It is a type of fold in which the rock layers are bent downward in a trough-like shape.
A syncline is a downward curving fold in a rock formation, where the strata dip toward the center of the structure. An anticline is an upwardly curving fold, with the strata rise upward toward the center of the structure.

A syncline is comprised of downward folding layers of rock.
The answer to the question is an aticline.
A syncline fold is concave downward, meaning the youngest rock layers are found in the center of the fold and the oldest rock layers are found on the outer edges of the fold.
