This study investigates the spatial distribution characteristics of karstic depressions that developed on a 2558 km 2 plateau with gently sloping in neritic (reef) limestones in the western section of the Bolkar Mountains. The 30,132 karstic depressions identified are located at elevations between 1315 and 2525 m, while 31°/km 2 slope and 5.6 km/km 2 drainage density are limited to the spatial distribution of depressions. In the central section of the study area at the anticlinal surface,

However, in the same area, the orientation of depressions also varies from ENE-WSW toward NE-SW from west to east. The left-lateral strike-slip Ecemiş Fault was effective in the formation of these orientations, with a NE-SW orientation close to the fault and ENE-WSW orientation farther away from the fault.
