Morphotectonic Development of Dolines on Mt. Bozdag (Karaburun Peninsula)

Abstract: This study investigated the morphometric and morphogenetic characteristics of dolines in the Bozdağ Massif, located in the north of Karaburun Peninsula. Dissolution dolines are one of the characteristic surface features of mid-latitude high karst plateaus, and doline morphometry is one of the methods commonly used to study the morphotectonic evolution characteristics of karst plateaus. In this study, an automatic extraction technique wasused with a high-resolution digital elevation model to determine the areal distribution, density and morphometric characteristics of dolines. After the dolines were identified, several morphometric parameters such as area, perimeter,circularity index, length, width and elongation rates were calculated. According to the analyses and results obtained, a total of 564 dolines were detected in the area, with a maximum density of 74 dolines/km2. All the dolines, with anaverage elevation of 1,080 metres, are located on limestone from the Camiboğazı Formation. The dolines extendin roughly NW-SE direction, parallel to lineaments in the area, which formed in relation to tectonic processes that started with palaeotectonic evolution and influenced the Karaburun platform in the Izmir-Ankara zone during the Cretaceous period
