【 摘 要 】

Kulon Progo Mountains have very distinctive shapes, where they have form of circular structures of volcano that are still intact and the other is not been intact. This morphology is the morphology of the remaining volcanoes formed by tectonics and certain volcanisms. The study was conducted through a series of interpretations of volcanic body distribution, alignment interpretation on satellite imagery and field work. The formation of Kulon Progo Mountain morphology is strongly influenced by tectonic and volcanic processes. The process of tectonics which produces strike-slip fault structures, normal faults, and uplifts have formed the lineaments of the valleys and hills with various pattern directions. The volcanism that has occurred forms the structure of volcanic remains. Distribution of volcanic rocks form a circular or semicircle structures because of the normal fault structures that have occurred.
