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)
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
No, basalt is not a gas. Basalt is an igneous rock formed from the rapid cooling of lava, which is molten rock. It is a solid material with a fine-grained texture.
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.
Igneous rock, and specifically basalt.
Rhyolite has a more felsic composition than basalt.
Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.
Basalt pushed into the crust by subduction will likely become metamorphosed into a rock called eclogite due to the high pressure and temperature conditions experienced in the subduction zone.
Marble (metamorphosed limestone) Slate (metamorphosed shale) Gneiss (metamorphosed granite)
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
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.

Quartz, it is metamorphosed.

That rock was not Basalt, it was different. This is not a diamond, just a normal Basalt.
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.
It is the past tense of the verb metamorphose, which means 'to change into something else'. An example of its use would be "He metamorphosed into a monster."
