Light-colored ignimbrite deposits, eroded into mesas bounded by steep-walled valleys, cap the central part of the island of Kos. The island is dominantly non-volcanic but contains Miocene to Pleistocene volcanic centers. The Kamari caldera is of mid-Pleistocene age and contains the 1.0-0.55 million-year-old, post-caldera Zini lava dome. The widespread Kos Plateau Tuff (145,000 years old) originated from a submarine source between Kos and Nisyros islands. Several geothermal areas are found on Kos.
