Show Hint
- Horizontal fold
- Vertical fold
- Upright fold
- Recumbent fold
The Correct Option is C
Solution and Explanation
Step 1: Interpret the stereoplot. The diagram shows: - Fold axis is horizontal (plotted as a line across the stereonet). - Axial plane is vertical (indicated by great circle line passing N-S).
Step 2: Characteristics of folds. - Horizontal fold → axis is horizontal, axial plane may be inclined. - Vertical fold → axis is vertical. - Upright fold → axis is horizontal and axial plane is vertical. - Recumbent fold → axis is horizontal but axial plane is nearly horizontal.
Step 3: Match with diagram. Here, axis = horizontal, axial plane = vertical → this is an upright fold.
Final Answer: \[ \boxed{\text{Upright fold}} \]
