The texture of a metamorphic rock can be influenced by several factors, including the original parent rock's composition, the temperature and pressure conditions during metamorphism, and the presence of fluids. The rate of cooling and the duration of metamorphic processes can also play a significant role. Additionally, the alignment of mineral grains, which occurs under directed pressure, can create foliated textures, while non-foliated textures arise in the absence of significant directional pressure.
The temperature and pressure conditions during metamorphism can affect the texture of metamorphic rock. Higher temperatures and pressures typically lead to a more pronounced foliation and mineral alignment, resulting in a finer texture. Additionally, the presence of fluids during metamorphism can also influence the development of specific textures in metamorphic rocks.
Quartzite
The Texture term for metamorphic rock which are not banded or layered is non-foliated metamorphic rock. Good examples are marble and quartzite.

Metamorphic rock can vary in texture, with some being rough due to the presence of mineral grains and others being smooth due to recrystallization of minerals during the metamorphic process. The texture of metamorphic rock depends on factors such as the original rock type and the intensity of heat and pressure.
Limestone is a metamorphic rock. Limestone is also has non-foiled texture.

Quartzite
a foliated rock is a metamorphic rock with a texture that gives the rock a layered appearance.

The mineral composition and texture of the parent rock can influence the resulting minerals and texture of the metamorphic rock formed. Additionally, the temperature and pressure conditions experienced by the parent rock will determine the extent of metamorphism and the types of minerals formed.
