Question

A fold in which the folding continues in the direction of the axis of the fold is ___________

(a) Plunging fold

(b) Non-plunging fold

(c) Similar fold

(d) Doesn’t exist

I have been asked this question in examination.

My doubt stems from Classification of Folds in chapter Folds and Folding of Engineering Geology

Answer 1

The correct option is (b) Non-plunging fold

For explanation I would say: Any fold in which the axis of the fold is essentially horizontal, that is, the plunging continues indefinitely in the direction of the axis of the fold is specifically described as non-plunging fold.
