Abstract(#br)The Lajes Ignimbrite on Terceira Island (Azores) records the last major pyroclastic density current-forming eruption of Pico Alto Volcano that occurred ca. 21<ce:hsp sp="0.25"/>kyrs ago. This comenditic trachyte ignimbrite contains up to 30<ce:hsp sp="0.25"/>vol% of crystals, mostly ano...
