	Hasn't voted	These "autobreccias" are pretty common in the old stratovolcanoes around here. I find very little description, but they clearly contain older pieces of the flows in a matrix of ash. I'd guess that there are some similar rocks -- though possibly at depth! -- in the Italian Penninsula and Sicily.
