The parent rock is exposed to varying degrees of pressure and/or heat either from depth of burial, exposure to a plutonic body of intense heat, or from pressures resulting from the collision of tectonic plates. The heat and/or pressure can transform the minerals inside the parent rock to new minerals, cause recrystallization of existing minerals, or reorganize the existing minerals into bands and layers. Exchanges of elements can also occur from hot fluids associated with plutonic intrusions. All of these processes take place without any melting of the parent rock.
What else can I help you with?
Which rock cannot be metamorphosed?
Rocks that are classified as non-crystalline or amorphous, such as obsidian, cannot be metamorphosed because they lack a defined crystalline structure. Metamorphism requires heat and pressure to rearrange the mineral structure of rocks, which cannot occur in amorphous materials.
What are some changes that occur when a sedimentary rock transforms into a metamorphic rock?
The process of metamorphism is one that changes or alters either the mineralogy or the texture, but typically both, of some pre-existing rock. Slate, marble and quartz are examples of metamorphism.
What metamorphic rock is formed from sandstone?
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
What type of metamorphic rock could be produced from mud?
If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.
CAN Metamorphic rocks occur from sedimentary and igneous rocks?
Yes, both sedimentary and igneous rock can be metamorphosed by heat and pressure.
What is metamorphic rock formed from sandstone called?
Sandstone can be metamorphosed into quartzite. Heat and pressure bake the sandstone and it becomes extremely hard.
What are 3 specific types of metamorphic rocks and what was their parent rock?
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
Name one metamorphosed rock from a sedimentary rock?
Quartzite
How metamorphosed rock is formed?
When a tectonic plate in a subduction zone, goes underneath another tectonic plate, the magma in the Earth's core causes the plate to break up and melt. This melted rock becomes magma, and when it pushes through the Earth's crust to create a volcanic eruption, the magma cools and becomes rock. This rock is Metamorphic rock.
What are some changes that occur when a sedimentary rock changes into a metamorphic rock?
To change a sedimentary rock to a metamorphic rock, you change it by time,heat, and pressure.
Granite rock subject to stress it may be metamorphosed into a rock called?
gneiss
Is marble an intrusive rock?
No, marble is a metamorphosed limestone, which itself is a sedimentary rock.
Is serpentine rock sedimentary or igneous?
Serpentine is a type of metamorphosed sedimentary rock.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
If a rock becomes a metamorphic rock no other changes in the rock cycle will occur true or false?
False. The rock may undergo further metamorphism, or it may melt and re-solidify into igneous rock, or it may be broken down into sediment at the surface and later become sedimentary rock.
If a rock becomes a metamorphic rock no other changes in the rock cycle will occur.?
False A+
