Foaliated rock can form in one or two ways. Extreme pressure may cause the mineral crystals in the rock to realign or regrow to form parallel bands. Foaliation also occurs as minerals that have different compositions separate to produce a series of alternation dark and light bands. Most nonfoliated metamorphic rocks share at least one or two main characteristics. First, the original rock that is metamorphosed may contain grains of only one mineral or contains very small amounts of other minerals.
Foliated metamorphic is when the rock texture is arranged in planes or bands. Nonfoliated is when the rock texture is not arranged in planes or bands.
A foliated metamorphic rock is one with a strong metamorphic layering (like slate).
foliated metamorphic describes the texture of metamorphic rock
because its just a question
non-foliated.
a banded texture
Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
A banded texture
Geologist classify metamorphic rocks according to the arrangement of the grains that make up the rocks and also it either being foliated or nonfoliated
Foliated are made of interlocking crystals, non-foliated are not.
Neither. The terms foliated and nonfoliated apply to metamorphic rocks. Andesite is igneous.

Foliated--those exhibiting layering (gneiss, slate, schists), and non-foliated--without layers (marble, quartzite).
Examples of non-foliated metamorphic rocks are quartzite and marble.
They are called foliated metamorphic rocks, and are said to exhibit foliation.
A banded texture
Foliation is an attribute of certain metamorphic rocks. Sandstone is a sedimentary rock that is not described as foliated or non-foliated.
