What is Devonian rock?
The rocks formed during Devonian time are known as the Devonian System. These rocks occur on all continents both at the surface and as substrata. Extensive areas of North America, South America, Europe, and Asia are underlain by Devonian rocks. Subsequent folding has made such rocks common in many ancient fold belts.
