Marble and quartzite are two examples of metamorphic rocks that lack banding and are massive. The lack of banding may indicate that the metamorphism may be due to a greater factor of heat than of pressure.
Metamorphic rocks are rocks that have their grains arranged in parallel layers or bands. Foliated rocks are formed under great pressure and heat, and when they cool they have a banded grain pattern.
Metamorphic rock is formed from another kind of rock under great heat and pressure. This process alters the mineral composition and texture of the original rock, creating a new type of rock. Examples of metamorphic rocks include marble, schist, and gneiss.
Metamorphic rock is formed through heat and pressure acting on existing rocks, causing them to recrystallize and change their mineral composition without melting. Examples include marble, slate, and schist.
The most common rock that makes up metamorphic rocks is shale, comprising around 75% of them.
The term is "metamorphic rock." Metamorphic rocks are formed from existing rocks that undergo changes in temperature, pressure, or chemical processes, leading to a new rock type with different characteristics.
nonfoliated rocks
Marble is a metamorphic rock that is massive and lacks banding. It forms from the recrystallization of limestone and is composed mostly of the mineral calcite. Marbles are often used in architecture and sculpture due to their aesthetic qualities.
Certain metamorphic rocks that do not exhibit foliation (banding, lamellar texture) like quartzite and marble are described as non-foliated.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
Metamorphic rocks are rocks that have their grains arranged in parallel layers or bands. Foliated rocks are formed under great pressure and heat, and when they cool they have a banded grain pattern.
Metamorphic rocks are formed from sedimentary rocks.
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks.

Gneiss is a metamorphic rock of variable composition with distinct banded layers. The layers or banding are called foliations, the result of the alignment of mineral grains in a direction perpendicular to the direction of pressure being exerted on the rock.
