AN IDEAL OUTCROP OF THE RECUMBENT FOLD

The recumbent fold is known to have an essentially horizontal axial plane. Its two limbs are essentially parallel to each other. By this consideration, the fold's two limbs are approximately parallel to the axial plane itself.

As appears in the explained sketch on the upper-right side of the photo,
A: axial plane.
B: upper limb.
C: lower limb.
D: closure of the fold, or it refers to the crest, peak, or summit of the fold where the axial plane passes through.
*: the core of the fold. The core is the area of the fold where the ancient rocks forming the fold place, or even the most recent one, according to the type of fold itself. In the current case of the recumbent fold, the core here (signed by *) refers to the ancient one.

Sincerely,
