Plunge of a fold
WebbFolds with inclined fold axis are called plunging folds. Determining the plunge and plunge direction can be a quite tricky task, if the exposure is 2-D. The photograph below shows plunging folds developed in glacial ice ("Pasterze", the largest glacier in Austria; 2.5cm diameter coin for scale). WebbWe can classify folds by hinge-line plunge as follows: Trains of folds in profile and 3-D The above terms apply to single folds. Commonly, multiple folds are observed in the same …

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. Figure 10.12 ... property record search sarasota county
