At temperature 600 degree centigrade and 14 kb basalt metamorphism produces?
At a temperature of 600 degrees Celsius and 14 kilobars pressure, basalt metamorphism typically produces minerals such as amphibole, pyroxene, and plagioclase feldspar, resulting in the formation of greenschist or amphibolite facies metamorphic rocks. These minerals form in response to the high temperature and pressure conditions, leading to changes in the original basaltic rock composition.
which rock is only formed by regional metamorphasim?
The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, and hornfels. Regional Metamorphism occurs over a much larger area. This metamorphism produces rocks such as gneiss and schist.
What gas does acid rain on limestone produce?
When acid rain comes into contact with limestone, it produces carbon dioxide gas. This occurs due to a chemical reaction that dissolves the limestone, releasing carbon dioxide into the atmosphere.
What is a soft white limestone used for drawing?
Chalk is a soft white limestone that is commonly used for drawing on chalkboards or sidewalks. It produces a smooth and dusty line that can be easily erased or smudged.
What condition produces the distinct layers of flat and elongated minerals in the foliated metamorphic rocks?
The condition that produces distinct layers of flat and elongated minerals in foliated metamorphic rocks is directed pressure, which causes the minerals to align perpendicular to the direction of pressure. This pressure helps give the rock its characteristic layered structure, known as foliation.
What is formed by metamorphism of limestone or dolomite?
The metamorphism of limestone primarily results in the formation of marble, while the metamorphism of dolomite produces a rock known as dolomitic marble or simply dolomite. During this process, the original carbonate minerals recrystallize under heat and pressure, leading to a denser and more crystalline texture. Marble is prized for its aesthetic qualities and is commonly used in sculpture and architecture.
Is contact metamorphism likely to produce foliation?
Contact metamorphism is less likely to produce foliation compared to regional metamorphism. This is because contact metamorphism involves high temperatures and low pressures, typically resulting in more localized metamorphic changes without the development of the extensive directional alignment of minerals that produces foliation.
What happens when you mix limestone with acid?
When limestone reacts with acid, it undergoes a chemical reaction that produces carbon dioxide gas, water, and a salt. This reaction is called neutralization and can be represented by the equation: CaCO3 + 2HCl -> CO2 + H2O + CaCl2.
At temperature 600 degree centigrade and 14 kb basalt metamorphism produces?
At a temperature of 600 degrees Celsius and 14 kilobars pressure, basalt metamorphism typically produces minerals such as amphibole, pyroxene, and plagioclase feldspar, resulting in the formation of greenschist or amphibolite facies metamorphic rocks. These minerals form in response to the high temperature and pressure conditions, leading to changes in the original basaltic rock composition.
What causes metamorphic rocks?
A metaporphic rock is formed when a rock is put under extreame heat and preasure for many (often thousands or millions) of years. This changes it into a new type of rock. This new rock is called a Metamorphic rock.
Are magmatic processes a form of geological metamorphism?
No, magmatic processes involve the movement and cooling of molten rock beneath the Earth's surface, while metamorphism involves changes in mineral composition, texture, or structure of rocks due to high pressures and temperatures. Magmatic processes can lead to the formation of igneous rocks, whereas metamorphism produces metamorphic rocks.
which rock is only formed by regional metamorphasim?
The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, and hornfels. Regional Metamorphism occurs over a much larger area. This metamorphism produces rocks such as gneiss and schist.
What type of metamorphism is taking place if there is high temp and low pressure?
The type of metamorphism occurring under high temperature and low pressure conditions is known as "contact metamorphism." This process typically happens when rocks are heated by nearby molten magma or lava, leading to changes in mineral composition and texture without significant pressure effects. As a result, the surrounding rocks, or country rocks, undergo localized metamorphic alterations. This type of metamorphism often produces features such as hornfels and can create new minerals that are stable at elevated temperatures.
Which non foliated rock forms only in a zone of contact metamorphism?
The non-foliated rock that forms exclusively in a zone of contact metamorphism is marble. Marble originates from the metamorphism of limestone or dolostone, typically occurring when rocks are heated by nearby molten magma. This process results in a crystalline texture and often produces a rock that is prized for its aesthetic qualities. Unlike foliated rocks, marble does not exhibit layered or banded structures due to the absence of directed pressure during its formation.
What gas does acid rain on limestone produce?
When acid rain comes into contact with limestone, it produces carbon dioxide gas. This occurs due to a chemical reaction that dissolves the limestone, releasing carbon dioxide into the atmosphere.
What produces high-grade metamorphism?
Extreme pressure and temperatures, such as those found at the base of a thickened crust.
