Uses of igneous rock basalt

Igneous rock basalt is an extrusive igneous rock formed when volcanic magma erupts onto the surface or into water and cools quickly. The speed of the cooling process makes mineral formation in basalt almost invisible and its composition fine-grained and consistent.Most of the roads and walkways of ancient Rome were paved with them. The large quantity of coarse, crushed rock that makes up the ballast along railroad tracks is frequently basalt, too.
