Basalt and obsidian are extrusive igneous rocks. Gabbro is an intrusive igneous rock.
Gabbro and basalt are both igneous rocks. However, gabbro is an intrusive rock, and basalt is an extrusive rock.
Gabbro is an intrusive rock, which means it formed underground. Basalt is an extrusive rock, which means it formed above ground .
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.

Obsidian
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
