Metamorphic rocks may display foliation, which is the layering, banding, or platiness that is associated with the rearrangement of mineral crystals due to directional pressure. Examples of foliated metamorphic rock include schist, slate, and gneiss.
Some minerals are typically formed due to the metamorphism of existing rock, and include those minerals that form due to the loss of water. When minerals that contain water can no longer exist due to heat and pressure, new minerals form. Garnet is a non-hydrous mineral that is often associated with metamorphic rock.
Metamorphism in rock can also manifest itself by the replacement of existing minerals by other minerals due to the invasion of the host rock by heated fluids which are created by a nearby magmatic intrusion.
Metamorphic rocks can also display a recrystallization and interlocking crystalline structure that is common when limestone or dolostone is metamorphosed into marble, or sandstone is metamorphosed into quartzite.
What else can I help you with?
How do you write a acrostic poem foe a metamorpic rock?
To write an acrostic poem about a metamorphic rock, start each line with a letter that spells out "metamorphic rock." Each line can describe a characteristic of metamorphic rocks, such as their formation through heat and pressure, unique textures, or the variety of minerals they can contain. Try to be creative and descriptive with your language to paint a vivid picture for the reader.
What five characteristics of a rock will make it a mineral?
For a rock to be considered a mineral, it must have a definite chemical composition, a crystalline structure, be naturally occurring, be inorganic, and have a solid form. Without meeting all of these characteristics, a rock cannot be classified as a mineral.
What are the five characteristics of a rock that would make it a mineral?
In order for a rock to be classified as a mineral, it must possess five characteristics: naturally occurring, inorganic, solid, have a definite chemical composition, and possess a crystalline structure.
What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation?
The oldest rock at the highest elevation is typically due to its resistance to erosion compared to surrounding rocks. This may be because the rock is more resistant to weathering and erosion processes or because it is harder and more durable compared to other rocks in the area. These physical characteristics allow the oldest rock to remain at higher elevations over long periods of time.
What three characteristics do geologists use to identify a rock sample?
Geologists typically use the rock's color, texture, and mineral composition to identify a rock sample. These characteristics help geologists categorize rocks into different types, such as sedimentary, igneous, or metamorphic, based on how the rock formed and its physical properties.
What is the metamorpic rock for sandstone?
Quartzite is the metamorphic rock for sandstone.
Is calcits a metamorpic rock sedementary rock or igneous rock?
calcite is a mineral.
When metamorpic rock is eroded deposited and cemented what does it turn into?
Sedimentary rock.
Does weathering change metamorpic rock to sediments?
yes
What are the three rocks that make the earth made of?
igneous rock, metamorpic rock and sedimentary rock
The word metamorpic means?
Rock that has undergone transformation by heat or pressure
Is a metamorpic rock formed from shale?
yes, it's slate. it goes from shale to slate to phyllite to mica schist.
How does metamorpic rocks form?
Metamorphic rocks are formed from an existing rock (of any of the three types) being subjected to a combination of heat and pressure.
What s does slate turn into if heated and squashed?
Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.
Is porphyry igneous sedimentary or metamorpic?
its igenoeus
How dos metamorpic rocks turn into chalk?
They don't.
Can metamorphic rock be changed by heat or pressure into a different kind of metamorpic rock?
Yes. Slates can be metamorphosed into phyllite, which in turn can become schist, which can finally become gneiss before melting entirely. The exact type of rock and mineral content depends on the temperature and pressure conditions of its formation.
