Devon


Devon was formerly called Devonshire, and is located in South West England between the Bristol Channel in the north and the English Channel in the south. So it covers the whole width of the peninsula, which ends with Cornwall. The county is famous for cliffs and beaches, and for the seaside resorts called British riviera. The county is divided by the Tees–Exe line gently dipping sedimentary rocks in the southeast and igneous rocks and folded sedimentary and metamorphic rocks in the northwest. The name was used by the geologists Roderick Murchison and Adam Sedgwick in the 1840s to name the Devonian era (395–345 Ma), because the rocks from this era were first identified here.
