Abstract In this study, spatial distribution characteristic of dolines and uvalas developed on plateau composed of Jurassic-Cretase neritic limestone and carbonates where found at west of Bolkar Mountains were analyzed. 30129 karstic depressions were detected in 2558 km2 area through examining of 1/25000 scaled 34 topographic maps. Dolines and uvalas comprise 85.6% and 14.4% of depressions, respectively. All depressions cover 154 km2 areas, in other words 1.17% of the investigation area. Maximum density reach up to 99 depressions/km2 based on 1x1 km grids. 1-5, 5-30, 30 depressions/km2 comprise 30%, 52%, 7% of the investigation area, respectively. Depressions disperse between 1315 m and 2525 m elevations, while 89% of them are located between 1650 and 2350 meters. Correlation between depression density and elevation was found positive (r = 0.96) up to 1900 meters, and a negative correlation (r = -0.91) was found after 1900 meter. A positive correlation (r = 0.86) was also detected between rate of elevation range and number of depression located at same elevation range. However, while rate of elevation range is more than rate of depressions up to 1850 meters and after this altitude level reverse situation is seen. Formation of depression becomes sparse when slope value increases because dolines and uvalas develop on low sloping areas at karstic plateau. For this reason, karstic plateaus covered by dolines and uvalas at The Taurus Mountains are restricted by steep slopes. Negative correlations are found between density and slope value (r= -028) and dissection index (r=-0.29). However, this correlation is not seen on plains covered by alluvium since alluvial cover inhibits superficial dissolution. Key Words: Karstic depression, correlations, spatial distribution, Bolkar Mountains, Central Taurus.
