Basalt is an extrusive volcanic rock formed from the decompression melting of Earth’s mantle. It is expelled through volcanic eruption and it produced grey to black and fine grained rock. It may contain minerals and elements. Basalt is also formed in other planets and asteroids.

∙ 6y agoThe rock basalt forms from the cooling and solidification of basaltic magma which is relatively high in iron and magnesium and relatively low in aluminum and silica when compared to andesitic and granitic magma.

∙ 14y agoThey are both formed by the crystallisation of magma.
Basalt is formed when basic (i.e. high iron and magnesium, low silica) magma freezes above ground as a lava flow, resulting in the very fine crystals.
Granite is the crystallised form of more felsic (silica-rich) magma, which has crystallised at depth within the Earth, resulting in a large crystal size.

What is the difference between gabbro and basalt?
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Where is basalt and gabbro formed?
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
What kind of rocks that are formed by volcanic activity?
Igneous Rocks: Basalt and Granite
What is basalt sedimentary ignous or metamorphic?
actually, it truly depends on the type of rock the metamorphic rock formed from. in other words, if it formed from a rock that held basalt in it, the rock has basalt in it. remember that a metamorphic rock can be formed by more than two different types of rock (such as metamorphic quartz, slate, "fool's gold", plus granite). it does not matter which class the metamorphic rock formed from (but if a m. rock such as m. quartz, there is more likely a chance of finding a trace of basalt), as long as it formed from two different class of rock (this does not always apply, for there can be a metamorphic rock made from two or more metamorphic rocks). i would get into geodes...... but that's another answer. :)
Is basalt formed by lava?
yes.... it cant +++ Strictly speaking no because lava is magma erupted from a volcano whereas a pluton is frommagma solidifying below ground. That doesn't exclude volcanoes accompanying plutons.
Is basalt formed from slow or rapidly cooling magma?
Basalt is formed from relatively rapid cooling magma.
What was the basalt and igneous rock formed by?
Basalt and igneous rocks were formed by what we would call magma/lava
What does basalt have to do with volcanoes?
Basalt is an igneous rock that is formed after a volcano erupts.
What is the meaning ofBASALTIC?
Pertaining to basalt; formed of, or containing, basalt; as basaltic lava.
Where is basalt born?
Basalt is formed when low-silica lava erupts from a volcano and later cools.
Metamorphic rock formed from basalt?
Schist
What is the difference between gabbro and basalt?
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Where is basalt and gabbro formed?
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
What sedimentary rock turns into the igneous rock basalt?
None. Basalt is formed by the rapid cooling of mafic (silica-poor) magma. It is not formed from sedimentary rock.
Why does basalt rocks cool slowly?
Basalt cools off quickly because it is formed under water.
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
How was MtStHelens formed?
YES Basalt is a soft rock
