Acigöl is a caldera in central Anatolia, near the town of Nevşehir, and only ~70 km from Kayseri. The approximately 7x8 km Pleistocene caldera is part of a larger, older buried caldera. The caldera walls are largely indistinct, but the caldera contains maars, lava domes, lava flows and pyroclastic cones. The lava flows range from basaltic flows, to obsidian. The youngest obsidian lava domes are found in the west, dated to about 20,000 to 15,000 years old. Numerous scoria layers are identified, with 13 from about 11,000 to 4,300 years identified in the Eski-Acigöl maar.
Five Holocene-age eruptions are recorded, between 2080 BCE and 7810 BCE.
