Description :
Karstification-based land subsidence was found in the Upper Tigris Basin with dimensions not seen anywhere else in Turkey. The subsidence was formed as a result of subsurface gypsum dissolution in Lower Miocene formation. This study describes the land subsidence and the caprock dolines in relation to formation mechanism and style. In addition, the effects of the land subsidence upon the evolution of the Tigris River valley are also discussed. The study was completed by the use of air photographs, topographic maps,a geology map,an hydrogeology map, and stratigraphic sections of drilled wells.
