5. Major fold Minor fold Parasitic fold

6. The difference between homogeneous and Inhomogeneous strain can be illustrated simply by the fold layer of the Figure.

7. Major fold Minor fold Drag fold The formation of parasitic fold.

8. First order media surface Second order median surface

9. In a single folded layer it is sometimes found that various orders of fold size exist(figure7-11). Infolded deposits the determination and correct extrapolation of These orders of periodicity may have great economic consequence.

10. Drag Fold And Parasitic Fold 1. The formation of drag fold. 2.The formation of parasitic fold. 3.The significance of drag and parasitic fold.

11. (1) Direct the direction of motion.

12. (2) Recover major fold

14. In normal strata, we can recover the major fold exactly according to minor fold.

15. θ2 θ1 θ According to Pumpelly’s Rule , θ =(θ1+θ2+……+ θn)/n
