Define non-foliated.
Understand the Problem
The question is asking for the definition of 'non-foliated', which typically refers to a type of metamorphic rock that does not have a layered or banded appearance. This term is often used in geology to describe rocks that formed under conditions where the mineral grains are not aligned in planes or layers.
Answer
Non-foliated metamorphic rocks do not have a platy or sheet-like structure.
The final answer is Non-foliated metamorphic rocks do not have a platy or sheet-like (layered) structure and lack distinct layers or bands.
Answer for screen readers
The final answer is Non-foliated metamorphic rocks do not have a platy or sheet-like (layered) structure and lack distinct layers or bands.
More Information
Non-foliated rocks, like marble and quartzite, are typically formed under conditions where pressure is equal in all directions, preventing the formation of layers.
Tips
Some students mistakenly believe that all metamorphic rocks have layers. It's important to note that non-foliated rocks do not.
