Harmless volcano

[Davejl]

These rocks tell a tale of explosive volcanic activity but it is rather peaceful now, well over half a billion years later. (The Bomb Rocks, Charnwood Lodge National Nature Reserve, Charnwood Forest, Leicestershire.)

Nicely composed and executed. So when how long before a volcano is no longer a volcano and just becomes a pile of rocks, a mountain, etc?

Thanks Dan, I don't know the answer to that, but certainly a very long time in the case of this one. At the time of this volcano Scotland hadn't yet become (geologically!) joined to England, and England was in the southern hemisphere. Some of the earliest fossils come from Charnwood (the first fossil in the world proved conclusively to belong to the Precambrian was found here). Fossils of the same sort have since been found at Mistaken Point in Newfoundland (which was not then geologically part of Canada).

If of interest, there is a pdf which explains the rock:
