- •
Mechanical stratification causes sequential thrusting in multiple orders.
- •
Contrasting thrust progression in the weak (upper) and strong (lower) layers.
- •
Frontal thrusting at higher and lower spatial frequency in weak and strong layers.
- •
Lower-order thrusts reactivate higher-order thrust in the upper weak layer.
- •
Mechanically layered systems develop segmented topography of the wedge.
