Here in UK, Lake District and Snowdonia, beautiful ignimbrites with the distinctive flattened pumice lumps in them. (Squashed by the overlying tuff while still semi molten). I gather that in Snowdonia the geologists puzzled out that the pyroclastic flows could keep right on down under the sea.
Yes, same term used over here. As distinct from 'flame structures' which are something quite different! I don't think flattened squashed pumice looks very like flames but early geologists had lively imaginations.
inyeresting and educational! Thanks

Cool, I learned to call those squashed pumice balls "fiamme," Italian for "flames," since they often have curly edges and tails.

Agreed, I never saw fiamme that remotely looked like flames!
