Basalt and obsidian are extrusive igneous rocks. Gabbro is an intrusive igneous rock.
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.
some examples of igneous rocks are granite,basalt,and rhyolite and driolite
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.
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.
Gabbro is a coarse-grained, intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. Basalt, on the other hand, is a fine-grained, extrusive igneous rock composed mainly of plagioclase feldspar and pyroxene. Basalt is typically found on the Earth's surface, while gabbro is usually found beneath the surface as intrusive rock formations.

Obsidian
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
== == Igneous rocks have formed from molten material either above (extrusive) or below (intrusive) ground level. Extrusive igneous rocks include obsidian, basalt, and rhyolite; intrusive igneous rocks include gabbro and granite.
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.
Magma is molten rock which rises from the mantle and into the crust and may solidify into igneous rock underground (e.g. granite or gabbro) or solidfy above ground (basalt, rhyolite, obsidian). === ===
