Types of Volcanoes

When the magma chamber has been completely filled, the type of eruption partly depends on the amount of gases and silica in the magma. The amount of silica determines how sticky (leve ...

Mount Pleasant Caldera
![](https://en.wikipedia.org/wiki/Special:FilePath/Mount_Pleasant_Caldera_magnetic_mapping.jpg?width=300)
The Mount Pleasant Caldera is a large eroded Late Devonian volcanic caldera complex, located in the northern Appalachian Mountains of southwestern New Brunswick, Canada. It is one of few noticeable pre-Cenozoic calderas, and its formation is associated to a period of crustal thinning that followed the Acadian orogeny in the northern Appalachian Mountains.It sits relatively near to the coastline.
