Volcanic Neck

 

a round or ellipsoidal cylindrical magmatic body composed of effusive rock or pyroclastic materials, or a combination of both. These materials originally filled the volcanic channel (vent) through which lava rose to the surface. When erosion occurs, the volcanic neck stands out sharply on the surface of the earth.
