Özet
A Fairy Chimney is a conical rock formation and typically found in the Cappadocia region of Turkey. It consists of a cap of hard rock resting on a cone-shaped pinnacle of softer rock. The geology of areas where Fairy Chimneys form typically comprises a thick layer of tuff (consolidated volcanic ash), covered by a thin layer of basalt or other volcanic rocks that are more resistant to erosion than the underlying tuff. Over time, cracks in the basalt allow the much softer tuff to be eroded and washed away. Fairy Chimneys are formed where a small cap or boulder of the original basalt remains, and protects a cone of tuff beneath it from erosion. Eventually, the tuff will be undercut to the extent that the cap falls off, and the remaining cone is then quickly eroded In this study, corrosion on the surface of fairy chimney, which is located in Selime district of Aksaray in Turkey, has been examined by digital close range photogrammetry. The fairy chimney has been evaluated by photogrammetric in two period. Its three dimensional (3D) model has been obtained. Its volume has been calculated from known heights. Corrosion in Fairy Chimney has been investigated.
