Basalt is known as an extrusive igneous rock because it was erupted by volcanoes as molten lava onto the Earth’s surface. It is usually black or dark gray in colour and weathers to dark green or brown. It tends to be dense and fine-grained and is often suitable for stone-flaking. Vesicular basalt is full of holes from air bubbles and is less useful for tools.
