The Springdale Caldera is a large Early Silurian caldera in west-central Newfoundland, Canada. It is at least 60 km (37 mi) long and 35 km (22 mi) wide, covering an area of more than 2,000 km2 (770 mi2). It is one of the few calderas in Newfoundland that form a large Silurian age volcanic field. Basalt, andesite, rhyolite, pyroclastic rocks, debris flows, breccias and red sandstone are present at the Springdale Caldera.[1]
