Attitudes of the two limbs of a non-plunging kink fold shown below are 045°, 20°SE and 045, 40°NW. The dip amount (in degrees) of the axial plane of the kink fold is (answer in one decimal place). NW SE 40 20° LIMB 2 LIMB 1
Answer: Dip amount of axial plane = 80° (towards SE)
Axial plane of the fold will be the bisector plane of two limbs.
The angle between two limbs = 180 - (20+40) = 120
Bisector...
