At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
Sandstone and basalt are changed by heat and pressure to form?
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
What mineral is formed when shale and basalt are exposed to low-grade metamorphism?
When shale and basalt are subjected to low-grade metamorphism, the mineral formed is typically clay minerals, particularly illite or chlorite. In the case of basalt, the alteration can lead to the formation of minerals like zeolites as well. The metamorphic process involves the recrystallization of existing minerals under heat and pressure, resulting in these secondary minerals.
Basalt can change into what metamorphic rock?
When basalt undergoes metamorphism, it can change into a metamorphic rock called greenstone. Greenstone is a fine-grained metamorphic rock that forms from the alteration of basalt through metamorphic processes like recrystallization and the growth of new minerals.
What are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
How does metamorphism affect basalt?
Metamorphism can cause basalt to undergo changes in mineral composition and texture, forming new minerals like chlorite, epidote, or amphibole. The original basalt can recrystallize into a denser, harder rock known as greenstone due to metamorphic heat and pressure. The degree of metamorphism can vary, with low-grade metamorphism likely resulting in minor changes, while high-grade metamorphism can drastically alter the basalt's appearance.
What makes the eclogite rock?
Extreme metamorphism of oceanic crustal basalt.
At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
Sandstone and basalt are changed by heat and pressure to form?
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
How does metamorphism affect baslt?
Basalt when metamorphosed turns to the following rocks: (LEAST PRESSURE AND TEMPERATURE TO THE MOST) + mineralogy -Greenschist-albite, epidote, chlorite -Amphibolite-amphioble, plagioclase feldspar -Granulite-calcium-rich pyroxene and plagioclase feldspar -Eclogite-sodium-rich pyroxene and garnet

How will basalt change in the future?
Basalt will not change it the future. Basalt will always be basalt. As rocks unlike humans or animals do not evolve. As they are inanimate objects. The however can be turned back into magma or lava, They can be eroded, or undergo metamorphism. Then then will change in shape and form but basalt will always have the same chemical composure as if it had a different one it would be a different rock.
Basalt can change into what metamorphic rock?

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 are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
How does limestone change into basalt?
It doesn't. They have different chemical compositions. Limestone is CaCO3. Basalt is mainly SiO4 and Fe. There is however an igneous rock composed predominantly of carbonate minerals known as carbonatite. This tends to form at zones of continental rifting. It isn't basalt however!
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.
