Answer: The phrase that describes non-foliated rocks is: "have grains in parallel layers, include quartzite and marble, tend to split along the bands or form from crystallized magma."
Explanation: Non-foliated rocks, such as quartzite and marble, do not have a layered or banded appearance like foliated rocks (e.g., slate or schist). Instead, their mineral grains are not arranged in parallel layers, and they do not show a distinct alignment of minerals. These rocks often form from the recrystallization of minerals in existing rocks, such as limestone turning into marble, or from the cooling and solidification of magma, as in the case of quartzite. They tend to have a more uniform texture and lack the layering characteristic of foliated rocks.
