Basalt is an extrusive fine grained igneous rock formed when the molten materials lava r.
Gabbro ˈ ɡ æ b r oʊ is a phaneritic coarse grained mafic intrusive igneous rock formed from the slow cooling of magnesium rich and iron rich magma into a holocrystalline mass deep beneath the earth s surface.
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.
All rocks of igneous origin consist of magma or molten earth that finds its way up to.
Slow cooling coarse grained gabbro is chemically equivalent to rapid cooling fine grained basalt much of the earth s oceanic crust is made of gabbro formed at mid ocean.
The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.
Diabase is the preferred name in north america while dolerite is.
