GEOLOGY

Detailed explanation-1: -Rocks that undergo brittle deformation tend to fracture into joints and faults.

Detailed explanation-2: -Brittle deformation mechanisms In natural rocks, the result of brittle deformation is often manifested as fractures, especially faults and joints.

Detailed explanation-3: -Brittle deformation is when rocks fail as rigid solids (Fig. 7.1A). The rocks will break, rather than bend, under these conditions to produce fractures. Brittle deformation occurs along discrete planes in the rock instead of involving the rock body as a whole.

Detailed explanation-4: -Faults are the places in the crust where brittle deformation occurs as two blocks of rocks move relative to one another. Normal and reverse faults display vertical, also known as dip-slip, motion.

Detailed explanation-5: -Faults occur when brittle rocks fracture and there is an offset along the fracture.
