Abstract
In this study, subsidence dolines formed in connection with gypsum karst at the east of city of Çankırı are dealt with, and their geomorphological properties, formation mechanism and process are examined.

Abstract
Çankırı şehri doğusunda, jips karstına bağlı olarak oluşan sübsidans dolinlerinin ele alındığı bu çalışmada; sübsidans dolinlerinin jeomorfolojik özellikleri, oluşum mekanizması ve süreci incelenmiştir. Bu alandaki sübsidans dolinlerinin bir kısmı dönemli akarsular tarafından açılmış, bir kısmı ise genellikle içerisinde göllerin bulunduğu kapalı dolinler hâlindedir. Jipsli seriler üzerindeki tedrici oturmalarla dolin oluşumuna yol açan sübsidans olayı, dolinlerin bulunduğu alanlarda yer altındaki jips çözünmesine bağlı olarak meydana gelmiştir. Buradaki sübsidans dolinleri büyük ölçüde fosil hâldedir. Pleistosen\'deki genel kaide seviyesi alçalmalarına bağlı olarak Acıçay\'ın yatağını derinleştirmesi, yerel su tablasında alçalmalarIn this study, subsidence dolines formed in connection with gypsum karst at the east of city of Çankırı are dealt with, and their geomorphological properties, formation mechanism and process are examined.
