Describing folds

TWT (msec) E CMP TWT (msec) 1.25 km Possible descriptive terms: Hinge ✕ Limb Axial surface Interlimb angle Things to label: Limb Interlimb angle Hinge ✕ ✕ Axial surface Upright symmetrical antiform with open rounded fold

Possible descriptive term: Monocline, a step shaped fold

Possible descriptive terms: Upright antiforms with open rounded folds, the eastern one is symmetrical, the western one is asymmetical and an upright angular symmetrical open synform.

Possible descriptive terms: Rounded inclined symmetric open antiform with several faults; two normal and one reverse. The faults indicate there has been more than one episode of deformation, and the faults are likely to have been re-activated.
