scoria cone

Small volcanic landforms formed from focused (single-vent) subaerial strombolian eruptions of basalt or basaltic-andesite magma. These features have an inverted cone-shaped profile and are generally circular in plan, although elongate scoria cones can be formed from multiple-vent volcanic eruptions (Cas and Wright, 1987, p. 371-372).
