Springdale Caldera
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 with an area more than 2,000 km2 (770 sq mi). It is one of the few calderas in Newfoundland that form a large Silurian age volcanic field and consists of basalt, andesite, rhyolite, pyroclastic rocks, debris flows, breccias, and red sandstone.[1]
