“…Widespread karstification in these areas has affected the people living here. Animal husbandry and agricultural activities carried out by people on these surfaces, which have a particularly difficult and faulty topography as karst, take place on the dolines, poljes, and paleo-valleys in these areas [50,51]. In this study, it was determined that people gradually accelerate KRD directly in karst areas.…”

Karst Rocky Desertification (KRD) is the reduction of vegetative productivity of this land with the release of bedrock as a result of the full or partial transportation of the fertile soil through natural processes and human activities in karst landscapes. The purpose of this study is to reveal the effectiveness of Remote Sensing methods in monitoring, mapping, and evaluating KRD. Landsat 8 OLI images were used to carry out these procedures. In monitoring this process, Karst Bare Rock Index (KBRI), Normalized Difference Rock Index (NDRI), Carbonate Rock Index 2 (CRI2), Normalized Difference Build-Up Index (NDBI), Normalized Difference Vegetation Index (NDVI), Dimidiate Pixel Model (DPM), Multi Endmember Spectral Mixture Analysis (MESMA) and Support Vector Machine (SVM) were used from the spectral indices. In order to evaluate the results obtained, KRD was divided into 4 basic classes such as none, mild, moderate, and severe. According to these classification levels, it was determined that SVM method had the highest accuracy. For this reason, it was concluded that the SVM method can be used effectively in determining KRD. In the study, it was concluded that the KRD strengthens as one goes from south to north and from west to east in the research area. This study points out KRD is one of the effective land problems in the Mediterranean region, Turkey.

“…The first studies on the Bolkardağı bauxites were been carried out by Wippern (1961) and Boroviczeny (1962). Different scientists have shown interest in the region (Nicolas and Özlu 1976;Özlu 1977;Karadağ et al, 2003;Temur et al, 2003;Yalçın et al, 2005;Karadağ et al, 2006;Yalcin and Ilhan 2008;Karadağ et al, 2009;Zedef and Doyen 2009;Kansun et al, 2010;Yalcin et al, 2010;Yalçın et al, 2012;Hanilçi 2013;Yalçın and Ilhan 2013;Köse et al, 2021;Şimşek et al;Atakoğlu et al, 2021;Atakoğlu and Yalçın 2021a;Atakoğlu and Yalçın 2021b).

The aim of this study is to determine the stratigraphic position of the bauxite deposits in the Ayrancı region, where the most important bauxite mineralization of the Bolkardağı region is located. In this context, the age of bauxite will be determined by determining the erosion surface associated with stratigraphic features during the formation of bauxite and the age of bauxite according to its side rocks. In the region, there are Permian-Cretaceous aged rocks belonging to the Bolkardağı Union, one of the main tectonic units forming the Central Taurus Mountains. Miocene units covering these rocks are surfaced in the study area. Karamanoglu ophiolite and older units are uncomfortably covered by Miocene aged Mazı and Divlek formations. Bauxite deposits are clearly seen in the Upper Permian aged Dedeköy formation. According to the field studies, the bauxites were formed in the Late Triassic - Early Jurassic interval, on the Upper Permian aged carbonate rocks and Lower Triassic aged shale - sandstone - limestone units and then deposited in caves and dolines within the carbonate rocks. The fact that bauxites are located above dolomites and below, within and above limestones is thought to be due to the different behavior of carbonate rocks.

“…The Taurus Mountains are the largest and most important karst terrain of Turkey and is forming a continuous karst belt across the southern part of the Anatolian Plateau. The Taurus Mountains range is highly karsti ed due to lithological, tectonic, and climatic features (Atalay, 2003;Nazik et al, 2019), and include many surface karst landforms such as poljes, paleo valleys, dolines, uvalas, ponors, and springs (Doğan et al, 2019;Öztürk et al, 2018b;Şimşek et al, 2021). Karst depressions (dolines and poljes) are of great importance in the search for tectonic and geomorphological development (Closson and Karaki, 2009;Doğan et al, 2019;Ekmekci and Nazik, 2004;Gracia et al, 2003;Mihljevic, 1994;Öztürk, 2020).The tectonic structure has a strong effect on development, density, orientation, and distribution of macro and micro karst depressions on the Taurus Mountains (Öztürk et al, 2018a, 2017).…”

The Taurus Mountains include the most important karstic terrain of Turkey and are divided into three parts the Western, Central, and Eastern Taurus. These mountains include many surface and subsurface karst landforms and the morphometric features of these landforms provide important data on the geomorphological and morphotectonic development of karst areas in the Taurus Mountains. Karstic depressions (poljes and dolines) constitute the most important surface landforms in the Western Taurus Mountains. In this study, a total of 7093 micro depressions (doline) and 74 macro depressions (polje) were detected and morphometric properties were calculated located in the Western Taurus Mountains. The poljes developed within the Beydağları Autochthon and Lycian nappes, while the dolines developed especially in the high plateaus within the Beydağları Autochthon. The morphotectonic development of both landforms is as below shortly. As a result of the northward movement of the African plate from the Early Cretaceous to the Late Miocene, the limestones accumulated in the shallow marine environment were compressed in the north direction and made a counterclockwise movement. Depending on this tectonic activity, the Lycian Nappes from the northwest and the Antalya Nappes from the east thrust over the Baydağları autochthon, and thus nappes, reverse faults and fold systems developed in the study area. The Western Taurus began to continentalization from the Oligocene and began to erode from the Miocene, and also with the erosion, the valley systems began to develop in the Western Taurus. The NE-SW and NW-SE directional normal faults have developed under the in uence of extensional tectonics since the Miocene, and this extensional tectonism has caused widespread development of the poljes in the study area. In addition, dolines and paleovalley began to develop in limestone areas at higher elevations with the lowering of the karst base level. All morphometric and morphotectonic processes reveal that the extension of both doline and polje areas in the study area are parallel to the elongation of tectonic structures in the study area.
