can you help me plz find more information thanks
What are the two categories of metamorphic rocks? What are the distinguishing characteristics between the two categories of rocks?
the answer?
Is that foilated and nonfoilated?
Scooby -- I already answered this question for you about an hour ago.

oops i didn't mean to do it again.
That's o.k.
By the way it's F O L I A T E D -- not foilated.
Yes, the two categories of metamorphic rocks are foliated and nonfoliated.
Foliated metamorphic rocks have a layered or banded appearance. They typically have visible mineral grains that are aligned parallel to each other, giving them a striped or sheet-like texture. Foliation occurs due to the physical and chemical changes that happen during the metamorphic process, such as the rearrangement of minerals under heat and pressure. Examples of foliated rocks include slate, schist, and gneiss.
On the other hand, nonfoliated metamorphic rocks do not have a layered or banded texture. They have a more uniform and granular appearance. Nonfoliated rocks typically lack mineral grains that are aligned parallel to each other. The lack of foliation is usually due to the presence of minerals that do not undergo significant rearrangement during the metamorphic process. Examples of nonfoliated rocks include marble and quartzite.
To find more information about the two categories of metamorphic rocks, you can refer to geology textbooks, online resources such as scientific websites and databases, or consult a geologist or a professional in the field. These sources will provide detailed explanations, images, and comparisons of foliated and nonfoliated metamorphic rocks, helping you gain a deeper understanding of their distinguishing characteristics.
