Quartz buckle folding geology
http://www.geologywales.co.uk/dgb/ Web3. The plunge of a fold can be described as the angle a fold axis makes with a horizontal surface. The axis of a plunging fold can therefore be described as having a certain strike (e.g. N 10 o W) and plunge (e.g. 20 o NW). Unlike dipping beds, the plunge of a fold axis is in the same direction as the strike of the axial plane. 4.
