Quartzite
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.
Quartzite,marble, and soapstone
Slate is a foliated metamorphic rock.
The parent rock of nonfoliated metamorphic rocks can vary, but some common examples include limestone, quartzite, and marble. These rocks typically form under high temperature and pressure conditions without the development of a layered texture like foliated rocks.
Quartzite is a nonfoliated metamorphic rock that is granular and composed mainly of quartz. It forms from the metamorphism of quartz-rich sandstone.
The two groups of metamorphic rock are foliated and nonfoliated. Metamorphic rocks can also be classified as contact and regional.
Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Nonfoliated rock
Nonfoliated metamorphic rocks lack a layered or banded structure, unlike foliated rocks. Instead, they typically have a granular or crystalline texture. This texture results from the recrystallization of minerals without the development of preferred orientations, giving the rock a more uniform appearance. Examples of nonfoliated metamorphic rocks include marble and quartzite.
A banded texture
Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure).
