  • Examples of non-foliated metamorphic rocks are quartzite and marble.
  • In these metamorphic rocks, mineral grains are not aligned with their long axis.
  • Non-foliated texture occurs under high temperature and low pressure conditions.
  • As minerals are able to grow, the size can be used to show a metamorphic change.
