The structural lineaments developed in the Kulon Progo Mountains, which is mainly composed of Tertiary volcanic rocks. The direction and distribution of these lineaments density differs from one area to another. This research was conducted to reveal the geological factor of controlling the variation of existing lineaments density. Lineaments delineation is done on the whole area on the satellite image of Kulon Progo Mountain area. From the lineaments map is then made a lineaments density variation map. Lineaments density variation map that are overlaid by volcanic rock distribution, based on the results of field studies, will result in a relationship between the geological structure density and the existing rock types and facies of volcanic rocks. The result of alignments density analysis shows high density values 3-6 km/km2 especially located at proximal volcanic rock facies. Low density values of 1-3 km/km2 are mainly located in medial and distal volcanic rock facies.
