What else can I help you with?
What would you call a granite that has undergone metamorphism and now exhibits foliation?
gneiss
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism?
shale and sandstone
What kind of metamorphosis has gneiss undergone with wavy or vertical bands?
Gneiss with wavy or vertical bands has undergone metamorphism known as foliation. This occurs when the minerals in the rock align to create a distinct layering or banding structure due to high pressure and temperature during metamorphism.
Are some rocks metamorphic AND sedimentary?
No. If a sedimentary rock has undergone even a low grade metamorphism, it is considered a metamorphic rock.
How does igneous rock becomes metamorphic?
Igneous rocks, such as granite, when subjected to extreme pressure and temperature will change to metamorphic rock. Evidence that an igneous rock had undergone metamorphism would include light and dark mineral banding; possibly with indications of partial melting in highly metamorphosed samples.
What horizon contains large pieces of broken up bedrock?
The regolith horizon contains large pieces of broken up bedrock. This horizon is composed of fragmented rock material that has undergone weathering processes, making it looser and more fragmented than the underlying unweathered bedrock.
What are the Levels of metamorphism?
The levels of metamorphism are low-grade, medium-grade, and high-grade. These levels are based on the temperature, pressure, and chemical changes that rocks undergo during metamorphism. Low-grade metamorphism occurs at lower temperatures and pressures, while high-grade metamorphism occurs at higher temperatures and pressures.
What aftercare does a patient who has undergone a mediastinoscopy receive?
Following mediastinoscopy, patients will be carefully monitored to watch for changes in vital signs or indications of complications of the procedure or the anesthesia.
Type of rockformed from sediments called?
A rock formed for sedimentary deposits is called a sedimentary rock. A sedimentary rock which has then undergone metamorphism is called a meta-sediment.
Is shist porous?
Yes, schist is typically porous due to its layered composition of minerals. The porosity of schist can vary depending on the specific mineral content and the degree of metamorphism it has undergone.
When a rock changes due to the surrounding pressure on all sides what has occured?
The rock has undergone metamorphism. Metamorphism is the process in which the mineral composition and texture of a rock change in response to heat, pressure, or chemical reactions. This can result in the formation of new minerals and changes in the rock's appearance and physical properties.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism between them?
Sedimentary rock and igneous rock would most likely have a zone of contact metamorphism between them. When molten magma intrudes into the surrounding rock, the heat and fluids released can alter the mineral composition of the adjacent rocks, leading to contact metamorphism.
