Rootless cone
A rootless cone , also formerly called a pseudocrater , [1] is a volcanic landform which resembles a true volcanic crater , but differs in that it is not an actual vent from which lava has erupted. They are characterised by the absence of any magma conduit which connects below the surface of a planet.

A pseudocrater is a volcanic landform which resembles a true volcanic crater , but differs in that it is not an actual vent from which lava has erupted. Pseudocraters are also known as rootless cones , since they are characterised by the absence of any magma conduit which connects below the surface of the earth. |

When hot lava is running over a wet surface, whether a swamp , a lake, or a pond, the event produces explosive gases. These break through the lava surface in an explosion (a phreatic eruption ), and the tephra builds up crater-like forms which can be very similar to real volcanic craters . These forms are also called rootless cones . They are characterised by not having a root, a magma channel which would connect them to the inner core of the earth. |
