What is the difference between fractures and deformation bands?
What will be an ideal response?
Ans: Deformation bands (tabular discontinuities) are thicker than fractures with comparable offsets (sharp discontinuities). Bands do not accumulate more than cm-scale offsets while fractures can show meter-scale offsets or more. Fractures show a loss of cohesion, while most deformation bands preserve cohesion or are mechanically stronger than the host rock.
