Metamorphic Rock Foliation. |
| Caption: |
In this animation, oceanic lithosphere is subducted under another plate at a convergent plate margin. The rocks under the ocean surface are compressed as the plates collide, deforming the strata and creating strong metamorphic conditions. An inset animation demonstrates the process of foliation. Two photos-of granite and gneiss-illustrate the before-and-after effects of foliation. |
