Basalt

Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of the Earth.

Basalt is used in construction e.g. as building blocks or in the groundwork, making cobblestones (from columnar Basalt) and in making statues. Heating and extruding Basalt yields stone wool, an excellent thermal insulator.
