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. (Wiki)

What is metamorphosed granite?
gneiss
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale is a sedimentary rock that can be metamorphosed into slate by "increased pressure" and heating.
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
Is basalt a gas?
No. Basalt is solid rock.
What rock makes slate?
metamorphosed shale
What is quartzite in relation to basalt?
Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.
Which rocks are metamorphic rocks?
Marble (metamorphosed limestone) Slate (metamorphosed shale) Gneiss (metamorphosed granite)
What is a metamorphosed coal?
Metamorphosed coal is called Anthracite.
What are 3 specific types of metamorphic rocks and what was their parent rock?
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
What is the hardness of the Metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.

Limestone can be metamorphosed into?
Limestone can be metamorphosed into marble through the process of recrystallization under high pressure and temperature conditions. The calcite crystals in limestone are transformed into interlocking crystals of calcite or dolomite in marble, resulting in increased hardness and a distinctive pattern and coloration.
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale is a sedimentary rock that can be metamorphosed into slate by "increased pressure" and heating.
What is an alkali basalt?
An alkali basalt is a particularly alkaline variety of basalt.
