Where is basalt and gabbro formed?
Basalt is formed from volcanic lava flows that cool quickly on the Earth's surface, while gabbro is formed from the slow cooling of magma deep underground. Both rocks contain similar mineral compositions, with basalt having fine-grained crystals and gabbro having coarse-grained crystals.
In what way is gabbro different from basalt?
Gabbro and basalt are both igneous rocks, but gabbro is a coarse-grained rock formed from slow cooling magma deep underground, while basalt is a fine-grained rock formed from rapid cooling lava on the Earth's surface. Gabbro typically contains more mafic minerals like pyroxene and olivine compared to basalt.
How does a basalt differ from gabbro?
Basalt is a fine-grained volcanic rock, usually dark in color, while gabbro is a coarse-grained intrusive rock that is also dark in color. Basalt tends to cool and solidify quickly on the Earth's surface, resulting in a fine-grained texture, whereas gabbro cools slowly beneath the surface, allowing larger mineral crystals to form.
Which igneous rock has the same chemical composition as basalt but a different grain size?
Gabbro has the same chemical composition as basalt (both are mafic rocks) but differs in grain size. Basalt has fine-grained crystals due to rapid cooling at the Earth's surface, while gabbro has coarse-grained crystals as it cools slowly beneath the surface.
How is basalt different from gabbro?
Basalt and gabbro are both igneous rocks, with major differences in grain size and where they form. Basalt has fine-grained crystals and forms from lava flows on the Earth's surface, while gabbro has coarse-grained crystals and forms from magma cooling beneath the Earth's surface.
What is the fine grained equivalent of gabbro?
The fine-grained equivalent of gabbro is basalt. Basalt is an igneous rock that forms from the rapid cooling of lava on the Earth's surface, resulting in smaller mineral crystals compared to gabbro.

Gabbro and basalt are both igneous rocks, but gabbro is a coarse-grained rock formed from slow cooling magma deep underground, while basalt is a fine-grained rock formed from rapid cooling lava on the Earth's surface. Gabbro typically contains more mafic minerals like pyroxene and olivine compared to basalt.
Can the minerals which form an intrusive rock also form the same rock but is an extrusive rock?
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
How does a basalt differ from gabbro?
Basalt is a fine-grained volcanic rock, usually dark in color, while gabbro is a coarse-grained intrusive rock that is also dark in color. Basalt tends to cool and solidify quickly on the Earth's surface, resulting in a fine-grained texture, whereas gabbro cools slowly beneath the surface, allowing larger mineral crystals to form.
What material is most abundant in oceanic crust?
Mafic igneous rock, predominately gabbro and its fine-grained equivalent, basalt.
What do granite and basalt in common?
They are both lithospheric igneous rocks formed by the cooling and solidification of magma/lava and both of them contains silicon.
Which igneous rock has the same chemical composition as basalt but a different grain size?
Gabbro has the same chemical composition as basalt (both are mafic rocks) but differs in grain size. Basalt has fine-grained crystals due to rapid cooling at the Earth's surface, while gabbro has coarse-grained crystals as it cools slowly beneath the surface.

Basalt and gabbro are both igneous rocks, with major differences in grain size and where they form. Basalt has fine-grained crystals and forms from lava flows on the Earth's surface, while gabbro has coarse-grained crystals and forms from magma cooling beneath the Earth's surface.
Which minerals are found in the igneous rocks gabbro and basalt?
Gabbro and basalt are both mafic igneous rocks and contain minerals such as pyroxene, plagioclase feldspar, and olivine. Gabbro typically has a coarser grain size compared to basalt, which has a fine-grained texture due to its rapid cooling at the Earth's surface.
Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
What is a dark coarse-grained intrusive igneous rock similar to basalt in mineral make up called?
The answer is Gabbro.
