A foliated metamorphic rock when crystals?
A foliated metamorphic rock forms when crystals combine and form visible bands
A foliated metamorphic rock forms when crystals .?
A foliated metamorphic rock forms when crystals combine and form visible bands
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
What is the difference between foliated and non-foliated rock textures?
In subject of metamorphic rocks, to be foliated is to have their grains arranged in parallel layers or bands. Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009
What Mineral alignment in a metamorphic rock usually gives the rock a porphyritic texture?
The alignment of large porphyroblasts in a fine-grained matrix results in a porphyritic texture in metamorphic rocks. This texture is commonly seen in rocks that have undergone regional metamorphism, where minerals like garnet or staurolite form large crystals in a finer-grained background.

How does a foliated metamorphic rock form?
Foliated metamorphic rocks form through directed pressure and heat acting on existing rocks, causing minerals to align in a preferred orientation. This alignment creates distinct layers or bands within the rock, giving it a foliated texture. Examples of foliated metamorphic rocks include schist, gneiss, and slate.
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
What is the difference between a foliated a non-foliated metamorphic rock?
The Process. Both foliated and nonfoliated rocks begin their lives as either sedimentary, igneous or another metamorphic rock. Type of Pressure. If the pressure applied to the recrystallizing rock is unequal, then a foliated rock will form.
What term is used to describe metamorphic rocks with a banded texture?
The two main groups of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks show layering and parallel alignment of flat mineral crystals (ex. micas). The "banded texture in metamorphic rocks" is one of the specific kinds of foliated textures. It is referred to as gneissic banding. Essentially, this texture displays alternating layers of light and dark minerals. These rocks are called gneiss- the light bands form from quartz and feldspars, while the dark ones form from ferromagnesian minerals.
A type of metamorphic rock in which mineral grains grow and rearrange but do not form layers?
Non-foliated metamorphic rock, such as marble or quartzite, is characterized by the absence of visible layering or banding. The mineral grains in these rocks recrystallize and grow in a uniform manner, without forming distinct layers like in foliated rocks. This type of metamorphism typically occurs under conditions of high pressure and temperature without the presence of directed stress.
What is the difference between foliated and non-foliated rock textures?
In subject of metamorphic rocks, to be foliated is to have their grains arranged in parallel layers or bands. Non foliated is when the rocks' grains are made randomly in no arranged pattern.Reference:Prentice Hall Earth Science 2009
In which plate boundary do foliated metamorphic rocks form?
Usually in convergent plate boundary scenarios.
What is a type of metamorphic rock in which mineral grains recrystallize but do not form layers?
Those would be non-foliated metamorphic rocks, like quartzite and marble.
What is difference between a foliated and an unfoliated metamorphic rock.?
Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while unfoliated metamorphic rocks do not have a layered structure. Foliated rocks form under directed pressure, while unfoliated rocks form under non-directed pressure. Examples of foliated rocks include schist and gneiss, while examples of unfoliated rocks include marble and quartzite.
What Mineral alignment in a metamorphic rock usually gives the rock a porphyritic texture?
The alignment of large porphyroblasts in a fine-grained matrix results in a porphyritic texture in metamorphic rocks. This texture is commonly seen in rocks that have undergone regional metamorphism, where minerals like garnet or staurolite form large crystals in a finer-grained background.
