Marble and quartzite are examples of massive metamorphic rocks that lack banding. Marble is formed from the metamorphism of limestone, while quartzite is formed from the metamorphism of sandstone. Both rocks typically have a uniform composition and lack the distinct layering or banding that is characteristic of other metamorphic rocks.
Metamorphic rocks that are massive and lack banding include non-foliated types like marble and quartzite. Marble forms from the metamorphism of limestone and is typically composed of calcite or dolomite, while quartzite originates from the metamorphism of sandstone and consists primarily of quartz. These rocks exhibit a uniform texture and structure, making them distinct from foliated metamorphic rocks that show layering or banding.
Lack of banding
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.
Non-foliated metamorphic rock, like quartzite and marble.
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.
Marble and quartzite are examples of massive metamorphic rocks that lack banding. Marble is formed from the metamorphism of limestone, while quartzite is formed from the metamorphism of sandstone. Both rocks typically have a uniform composition and lack the distinct layering or banding that is characteristic of other metamorphic rocks.
nonfoliated rocks
Lack of banding
Metamorphic rocks generally are not categorized by their roughness, but instead by their degree of foliation or lack of it. The "roughness" of a metamorphic rock is unknown unless sample is in hand.
Non-foliated
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.
Quartzite is a common non-layered metamorphic rock formed from sandstone. It is characterized by its hardness and lack of foliation.
Non-foliated metamorphic rock, like quartzite and marble.
Metamorphic rock can be either foliated or non-foliated. Foliated metamorphic rocks have layered or banded textures, while non-foliated metamorphic rocks lack these layers and have a more uniform appearance. Examples of foliated metamorphic rocks include schist and gneiss, while examples of non-foliated metamorphic rocks include marble and quartzite.
Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.
Drought= lack of water Wildfire= massive fires
