This thesis attempts to seek a relationship between the joints developed in the ignimbrites and the rock settlements carved in the same units. Orientation of rooms, directions of walls and joints (both in the rooms and in the field) are input data used in the study. Two sites in Cappadocia (Eskigümüşler and Çanlikilise) are selected to investigate the relationship. Both sites are carved within the same ignimbrite (Kizilkaya) and are located on the south-southeastern slopes of the ignimbrite scarp. Measurements taken from 61 rooms of the former and 27 rooms of the latter are analyzed for the room and joint directions, joint locations in the room and joint densities both in the rooms and in the field. Conclusions derived from the analyses are: 1) The rooms are oriented oblique to joint strike to get the maximum sunlight, 2) Joint directions in the rooms strike in one single direction and greatly differ from the field joint directions, 3) Density of the room joints is less than the field joints indicating that joint spacing is an important factor in the selection of sites, 4) Joints in the Eskigümüşler sites are concentrated towards the margins of the room while an opposite observation is made for the Çanlikilise site, 5) Total length of joints in the largest rooms are relatively shorter.
