Erosional caves can be found in almost any kind of rock, from hard granite to soft claystones, and even including limestone. In fact erosion can be a very active process in caves originally formed by solution caves as well, but usually occurs after the cave has drained and surface streams are pirated into the cave. Erosion tends to produce tall, canyon-like passages. Running water on glaciers may sink into crevasses and melt a path through the glacier to form glacier caves. These often show pronounced scalloping on the walls and ceilings, and are often decorated with ice formations.

However, this geologic term is used in speleology in a slightly different meaning, which has historic reasons. The first cave explorers saw cave rivers, which were rather similar to subsurface rivers, gorges and erosions as known before. So they interpreted the caves as a result of the erosion of underground streams.
