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.


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


What is metamorphosed basalt?

Metamorphism is when a rock of any particular composition get heated and put under pressure such that it partially melts and the chemical elements that make up the minerals rearrange to form new, usually high temperature and pressure versions of the original minerals since the composition is the same. The pressure is provided usually over a long period of burial or tectonic movement and the heat is either on a regional or local scale (contact metamorphism) where the rocks being metamorphosed have a magma intruded next to them. Basalt is an igneous rock (erupted from volcano) and is fine grained, ie. they cool quickly. Depending on the particular temperature and pressure it undergoes its minerals will change into particular other minerals. Metamorphic rocks of particular composition have been put into what are called 'facies'.

Metamorphosed basalts are also important hosts for a variety of hydrothermal ore deposits, including gold deposits, copper deposits, volcanogenic massive sulfide ore deposits and a few others.

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.

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.

Is basalt a solid?

Yes, basalt is a solid at standard temperature and pressure.


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.


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?

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.
