Yes, "concretions" I think they are called?Being a geologist, but not a local (not even close, I'm in California), nor familiar with the location, the violent ejection theory is probably unlikely. Violent ejecta are usually associated with a lot of gases, which also typically results in quick cooling (quenching). Quick cooling is how you retard crystal growth and create glass (vitreous rocks like obsidian and the like). These are probably sedimentary or metamorphic rocks, but just my two cents. Very cool find! Being a rock nerd, "I dig it!"
Yes thanks vern, knew they were iron stones and history. It’s the spherical nature of them that interested me. Being that they’re so dense and durable, they must have formed/cooled that way? I reckon I’ve got about £500 worth then.@The History Man the stones your collecting are Iron stones, its what they used to mine down here,
The Iron stone mine used to pay a couple of quid each for them not sure if they still do....
