Foliated.
Metamorphic rocks such as marble and quartzite are said to be non-foliated because their mineral grains are not arranged in parallel layers or bands like in foliated rocks such as slate or schist. This lack of alignment gives non-foliated rocks a more uniform texture and appearance.
Soapstone is a metamorphic rock composed of the mineral talc. Soapstone is a non-foliated metamorphic rock with a microcrystalline texture. It is very soft and can be easily scratched.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
The metamorphic rock you are referring to is called foliated rock. Foliated rocks have mineral crystals aligned in parallel layers or bands, resulting from the re-alignment of minerals due to pressure and heat during metamorphism. Examples of foliated rocks include slate, schist, and gneiss.
The rock you are referring to is talc, which is a soft metamorphic rock composed mainly of the mineral talc. Talc is known for its greasy or soapy feel and is commonly used in cosmetics and as a lubricant.
The metamorphic rock commonly found in a pencil is graphite. Graphite is a soft, black mineral that forms from the metamorphism of carbon-rich sediments. It is composed of layers of carbon atoms arranged in a hexagonal pattern.
Marble is a type of metamorphic rock, composed primarily of the mineral calcite or dolomite.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
What kind of metamorphic rock has its mineral grains arranged in planes or bands
Nonfoliated metamorphic rock would be:Quartzite - composed of the mineral quartz; metamorphosed sandstoneMarble - composed of the mineral calcite; metamorphosed limestone
Mica.
Schist is a metamorphic rock that exhibits parallel alignment of mineral grains, giving it a foliated appearance. This alignment is typically a result of regional metamorphism where intense pressure and temperature conditions cause the minerals to recrystallize in a preferred orientation.
