What type of fold forms in an area of intense deformation where one limb of the fold has been tilted beyond vertical?

Question

Quizplus · Accepted Answer

An overturned fold is a type of fold where one limb has been tilted beyond vertical. This typically occurs in areas of intense deformation where the rock layers have been subject to significant stress and pressure. The other limbs of the fold may be less steeply inclined or may be overturned as well. Asymmetric folds and plunging folds may also occur in areas of deformation, but they don't necessarily involve the extreme tilting seen in an overturned fold.
