Radial walls extending outward from a volcano are generally formed by dikes, which are vertical or near-vertical sheets of magma that intrude into the surrounding rock. Sills are horizontal sheets of magma, plugs are solidified magma that clogs the central vent of a volcano, veins are usually mineral-filled fractures in rock, and clay pans are flat areas of hardened clay soil.
