!Fairy Chimneys Rock Structures Mount Erciyes, Mount Hasandag and Mount Göllüdag were active volcanoes in the geological periods. Alongside with many other volcanoes, eruptions of these volcanoes started in the Early Miocene (10 million years ago) and have continued until the present day. The lava produced by these volcanoes, under the Neogen lakes, formed a layer of tufa on the plateaus which varied in hardness and was between 100 and 150m thick. Other substances in the layer are ignimbrite, soft tufa, tufa, lahar, asy, clay, sandstone, marn, basalt and other agglomerates. Plateaus, having been essentially shaped with the lava from the bigger volcanoes, were continuously altered with the eruptions of smaller volcanoes
