Acigöl-Nevsehir caldera is located in central Turkey and is traversed by the national highway between the towns of Acigöl and Nevsehir. The elliptical 7 x 8 km wide late-Pleistocene caldera is part of a now partially buried larger caldera and contains a group of maars, lava domes, basaltic lava flows, and pyroclastic cones. Three groups of obsidian lava flows have been dated; pre-collapse flows between about 190,000 and 180,000 years before present (BP), 75,000 yrs BP lava domes (such as Taskesik Tepe on the eastern side of the caldera) post-dating formation of the Acigöl-Nevsehir caldera, and young lava domes on the western caldera floor about 20,000 to 15,000 years old. Thirteen scoria layers from local tephras erupted between about 11,000 and 4300 years ago were found in sediment cores in the late Pleistocene Eski Acigöl maar. An ash layer from the Acigöl-Nevsehir volcanic group overlies 2300-1850 BCE artifacts of Roman-Cappadocian age.
