Morphometric Properties of Solution Dolines in the Eastern Taurus
Abstract
Dolines are the characteristic landforms of karst plateaus in the middle latitudes and there are many dolines on the high karst plateaus in the Eastern Taurus Mountains. The main purpose of this study is to determine the spatial distribution and morphometric properties of dolines in the Eastern Taurus Mountains. In the study, 217 topography maps with a scale of 1/25.000 were scanned and 36.188 dolines were detected on 28 karst plateaus covering an area of 8.554 km2 in total. The elevation of dolines ranges between 640 meters and 3.335 meters. The average doline density in the study area is 4.5 dolines/km2. The maximum doline density is observed in the Malatya Mountains with 128 dolines/km2 and it exceeds 50 dolines/km2 in Aladağlar, Alandaş Mountain, Yama Mountain, and Berit Mountain. Areas with high doline density (> 50 doline/km2) occupy very little space (0.2%), while areas with very low and low doline density take up a lot of space (98.5%). While the average area of the dolines in the Eastern Taurus is 3.287 m2, the average perimeter is 170 meters. The average value of the circularity index of the dolines is 1.29, and they have lost their circular form. While the long axis length of the dolines is 62 meters on average, the short axis length is 37 meters on average. The average elongation ratio value of the dolines in the field is 1.58, and the dolines show semi-elliptical characteristics. While the dominant orientation of the dolines is in the NE-SW direction, secondary orientations were detected in the WNW-ESE and NNW-SSE directions. In order to determine the relationship between the fault and fold systems and doline extensions in the Eastern Taurus Mountains, the doline orientations of each plateau were mapped. According to the obtained orientation distributions, the northern part was shaped by the East Anatolian Fault (EAF), the western part by the EAF and the Southeast Anatolian Thrust, and the eastern part by the Southeast Anatolian Thrust.
