What are the differences between basalt and gabbro?

Gabbro and Basalt are Related. Gabbros are equivalent in composition to basalts. The difference between the two rock types is their grain size. Basalts are extrusive igneous rocks that cool quickly and have fine-grained crystals. Gabbros are intrusive igneous rocks that cool slowly and have coarse-grained crystals. read more

Basalt and Gabbro are both Mafic Igneous rocks, having same mineralogy. The main difference between them is the process through which it formed and texture. Basalt is an extrusive fine grained igneous rock formed when the molten materials (lava) rapidly cooled near earth surface or on the earth surface. read more

As nouns the difference between basalt and gabbro is that basalt is (mineral) a hard mafic igneous rock of varied mineral content; volcanic in origin, it makes up much of the earth's oceanic crust while gabbro is (rock) a name originally given to a kind of serpentine, and now generally used for a coarsely crystalline, igneous rock consisting of lamellar pyroxene and labradorite. read more

The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock. Metamorphic rocks Metamorphic rocks are classified based on foliation as foliated rocks and non-foliated rocks. read more
