1 Ductile (Plastic) Deformation Folding

2 Stress vs. Strain Rheology Deformation Force

3 Folded Structures 1.Anticlines 2.Synclines 3.Monoclines 4.Basins 5.Domes

4 Anticlines

5 Anticline - oldest rock formation in the middle.

6

7 Syncline - youngest rock formation in the middle.

8 Syncline in Eastern Tennessee

9 Plunge - the inclination of the fold axis

10 Plunge Measured from a horizontal line.

11 Monocline

12 Peru Monocline – caused by basement-block faulting
