What is an amphibolite?
An amphibolite is a class of metamorphic rock comprised mainly of amphibole with some quartz and other minerals.
Is amphibolite mineral a felsic mafic or intermidate?
Is mineral amphibolite a felsic, mafic or intermidiate in term of color
What is amphibolite made of?
Amphibolite is a type of metamorphosed mafic igneous rock. It is composed largely of minerals such as hornblende and plagioclase.
Where is amphibolite found?
Amphibolite is a metamorphic rock. It forms when basaltic rock is heated to high temperatures under pressure. Without the added pressure the basaltic rock that would be yielded is green schist.
What is the parent rock of amphibolite?
Amphibolite is typically formed from the metamorphism of basalt or gabbro, which are both mafic igneous rocks. The high temperatures and pressures during metamorphism lead to the formation of amphibole minerals, giving rise to the rock type known as amphibolite.
What is the color of amphibolite?
Amphibolite is the metamorphic form of amphibole, also known as hornblende. Amphibolite usually has a black and white, lightly foliated appearance.
What rock does basalt become after metamorphosis?
Basalt can metamorphose into a rock known as amphibolite. Amphibolite forms when basalt is subjected to high temperatures and pressure, leading to recrystallization of minerals and the development of a new texture.
What is the texture of amphibolite?
Amphibolite typically has a medium to coarse-grained texture with a foliated structure. It consists mainly of amphibole minerals such as hornblende, which gives it a dark color and a shiny appearance.
What do you do with amphibolite?
Amphibolite is often used in construction. Amphibolite is commonly used on the faces of buildings, as well as paving.
Where can amphibolite be found?
Amphibolite can be found in regions with high-grade metamorphic rocks, typically in mountain belts or areas with tectonic activity. Examples include the Appalachian Mountains in the United States, the Scottish Highlands, the Alps in Europe, and some parts of Japan and New Zealand.
Is amphibolite foliated?
Yes, amphibolite is a foliated metamorphic rock. It forms through the metamorphism of basalt or gabbro and typically exhibits a well-developed foliation called schistosity due to the alignment of its mineral grains.
Is amphibolite magnetic?
Amphibolite is generally not considered magnetic. It is primarily composed of amphibole minerals and plagioclase feldspar, which do not exhibit significant magnetic properties. However, if amphibolite contains accessory minerals with magnetic properties, such as magnetite, it may show some weak magnetic response. Overall, its magnetic characteristics depend on the specific mineral composition of the rock.
