On the other hand, magma erupted at the surface is chilled so quickly that the individual minerals have little or no chance to grow.
WebGabbro is a phaneritic, mafic intrusive igneous rock created deep beneath the earth's surface by the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass. It cools slowly but finely and is chemically comparable to basalt. Gabbro forms near mid-ocean ridges and makes up much of the earth's marine crust.
