Metamorphic rocks with a layered or banded look are referred to as foliated.
Well, friend, banded rocks are often made up of layers of different materials, like sedimentary rocks such as sandstone or shale. Non-banded rocks, on the other hand, can include igneous rocks like granite or basalt, which are formed from cooled magma without distinct layers. Both types of rocks have their own unique beauty and story to tell in the great tapestry of the Earth.
A metamorphic rock with definite layers is called a foliated rock. Examples include slate, schist, and gneiss, which form due to intense pressure and heat causing minerals to align in distinct layers. Foliated rocks often have a banded appearance due to this layered structure.
foliated metamorphic rocks. The alternating layers are caused by the alignment and segregation of minerals during the metamorphic process, resulting in a banded or layered appearance. Examples of foliated metamorphic rocks include gneiss, schist, and slate.
Metamorphic rocks that have a banded appearance due to the alignment of minerals are called foliated metamorphic rocks. This banding occurs when pressure causes the minerals to align perpendicular to the direction of the stress, creating distinct layers or bands. Common examples include schist and gneiss. The foliation reflects the mineral composition and the conditions under which the rock was formed.

Those are two types of metamorphic rocks. Banded metamorphic rocks are when rocks layer into layers and they look like strips or Bands. Non banded is the opposite of banded

Metamorphic rocks with a banded or striped appearance are called foliated rocks. These bands or stripes are formed due to the alignment of mineral grains or the presence of alternating layers of different minerals. Examples of foliated metamorphic rocks include gneiss, schist, and slate.

Metamorphic rocks with grains arranged randomly are said to be non-foliated. This means they do not have a layered or banded structure like foliated metamorphic rocks. Examples include marble and quartzite.
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.

Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.
