Deformation of Rocks - Eclass

4 important questions on Deformation of Rocks - Eclass

What happens at low values of confining stress? At shallow stress?

Brittle failure or shattering (FAULTING) occurs

What happens at high values of confining stress? At deeper depth?

Ductile failure/ plastic deformation (FOLDING) is favoured

Does weak rocks experience ductile or brittle deformation?

  • Weak rocks = experience ductile deformation and tend to fold
  • It is weak .'. It is easy to manipulate
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

Do strong rocks experience ductile or brittle deformation?

  • Strong rocks = brittle fracture and more likely to fault
  • It is strong .'. It easily breaks think of wood, its like glass

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
