... Many eruptions are relatively quiet and are characterized by the calm, nonviolent extrusion of lava flows on the earth's surface. If the material is fluid in nature (solid and semi-solid) this type of flow is called Pryoclastic Flow (the typical hot lava that flows down a volcano). Other eruptions, ...

Basalt
Basalt (pronounced /bəˈsɔːlt/, /ˈbæsɒlt/, /ˈbæsɔːlt/, or /ˈbeɪsɔːlt/)is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
