Fold and thrust belts:
A) form where thrust faults cut through a thick sequence of layered rocks
B) contain cleavage and joints
C) displace older rocks over younger ones
D) all of these
Fold and Thrust Belts
Regions in the Earth's crust where the layers of rock have been folded and thrusted over one another due to compressional forces, often found in mountainous areas.
Thrust Faults
Types of reverse faults that have a dip of 45 degrees or less, meaning they are nearly horizontal; significant in shaping landscapes by pushing rocks upwards.
Cleavage
A geological term referring to the tendency of minerals to break along flat, parallel planes of weakness in their crystal structure.
- Describe the structural features that can form in association with faults, including folds, cleavage, and shear zones.
- Understand how metamorphism is related to geological structures such as folds, thrust belts, and mid-ocean ridges.

Final Answer :
D
Explanation :
Fold and thrust belts are geological structures that form in regions of compressional tectonics where thrust faults cut through a thick sequence of layered rocks, leading to the displacement of older rocks over younger ones. These belts often contain various structural features, including cleavage and joints, due to the intense deformation processes involved.
