It forms from the slow crystallization of magma below earth s surface. Basalt is a very fine grained dark coloured extrusive igneous rock which is formed due to cooling and solidification of molten lavas at the surface of the earth. Many quarries are now. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
