“…Because of intense karstification, a surface drainage network is quasi‐absent in the study area (e.g. Öztürk et al ., ). Only small seasonal streams develop along the main valleys fed by water originating from melting of snow.…”

We present details on the timing of glaciations during the late Quaternary in the western Taurus Mountain Range of Turkey. Twenty‐five boulders from prominent moraines in three northern glacial valleys of Mount Dedegöl (37.40°N, 31.17°E, 2992 m above sea level, ∼15 km west of Lake Beyşehir) were dated based on cosmogenic 36Cl surface exposure. The geomorphological mapping of the N‐NE‐trending Sayacak, Kisbe and Karagöl valleys and their in situ produced 36Cl glacial chronology revealed several glacial episodes during the late Quaternary from (pre‐Last Glacial Maximum (pre‐LGM) to early Holocene. Pre‐LGM glaciations are represented by a push‐hummocky moraine complex in the northern Sayacak Valley and dated to 29.7 ± 2.9 ka. The ages obtained from these hummocky moraines give substantial evidence regarding ice accumulation before the global LGM. In the same valley, glaciers reached their maximum positions at the LGM and deposited lateral moraines at 19.7 ± 1.6 ka. Lateglacial moraines were dated to between 16.4 ± 0.7 and 12.0 ± 1.0 ka in the nearby east‐facing Karagöl valley. The youngest glacial stages occurred during the Younger Dryas stadial (11.5 ± 0.8 ka) and early Holocene (9.8 ± 1.4 ka) in Mount Dedegöl.

“…Esse tipo de análise quantitativa retira o fator subjetividade nas análises comparativas entre regiões cársticas (Ferrari et al, 1998) e permite revelar dados e informações anteriormente não observadas, possibilitando novas hipóteses (Ford e Williams, 2007). Nesse sentido diversos trabalhos internacionais tratam sobre as formas clássicas ou uso de novas tecnologias de mapeamento de dolinas, análises morfométricas e interpretações ambientais correlatas (Denizman, 2003;Seale et al, 2008;Siart et al, 2009;Faulkner et al, 2013;Kovačič e Ravbar, 2013;Pardo-Igúzquiza et al, 2013;Zhu et al, 2014;Kobal et al, 2015;Aguilar et al, 2016;Gessert, 2016;Keskin e Yılmaz, 2016;Lee et al, 2016;Pardo-Igúzquiza et al, 2016;Telbisz et al, 2016;Wu et al, 2016;Zhu e Pierskalla, 2016;Čeru et al, 2017;Wall et al, 2017;Cahalan e Milewski, 2018;Chen et al, 2018;Harris et al, 2018;Hofierka et al, 2018;Öztürk et al, 2018).…”

O carste se desenvolve sobretudo pela ação da dissolução em subsuperfície, na interação da água com rochas solúveis, especialmente as carbonáticas. Apesar do processo de carstificação nem sempre se apresentar em superfície, a ocorrência de dolinas, feições consideradas características, indica maior proeminência desse fenômeno. Muitos trabalhos internacionais se dedicaram ao mapeamento de dolinas com objetivos diversos, como comparar o nível de carstificação e evolução dos ambientes onde estão inseridas, relacionar o desenvolvimento destas feições com estruturas geológicas ou realizar análises hidrológicas de caráter ambiental. Por outro lado, são poucos os trabalhos com esta temática realizados no Brasil, parte concentrada em regiões cársticas tradicionais, como o Vale do Ribeira-SP, Chapada Diamantina-BA e nos carbonatos de Minas Gerais, e os demais dispersos pelo país, muitos em rochas não carbonáticas. Neste sentido o objetivo deste artigo é realizar uma revisão dos trabalhos sobre mapeamento de dolinas, com enfoque nos aspectos morfométricos e quantificação, visando especialmente elaborar um primeiro panorama sobre como o tema é abordado no Brasil. Observou-se que a maior parte dos estudos nacionais alcançou resultados de frequência (nº/km²) bastante inferiores aos identificados em estudos internacionais. Essa discrepância foi atribuída a alguns aspectos, como a adoção de fontes de dados inadequadas em escala abrangente, a escolha de áreas muito extensas para a análise ou de fato a investigação em áreas pouco propícias a ocorrência de dolinas. An Overview of Doline Mappings in Brazil, Karst's Elemental Features A B S T R A C TKarst develops mainly by the action of dissolution in subsurface, in the interaction of water with soluble rocks, especially carbonates. Although the karsification process does not always appear on the surface, the occurrence of dolines, features considered characteristic, indicates a greater prominence of this phenomenon. Many international works have been devoted to the mapping of dolines with different objectives, such as comparing the level of karsification and evolution of the environments in which they are inserted, to relate the development of these features to geological structures or to perform environmental hydrological analyzes. On the other hand, there are few studies on this subject in Brazil, concentrated part in traditional karst regions such as Vale do Ribeira-SP, Chapada Diamantina-BA and carbonates of Minas Gerais, and the others scattered around the country, many in non-carbonate rocks. In this respect, the objective of this article is to review the work on doline mapping, with a focus on morphometric aspects and quantification, aiming in particular to elaborate a first overview about how the theme is approached in Brazil. It was observed that most of the national studies reached frequency results (n°/km²) much lower than those identified in international studies. This discrepancy was attributed to some aspects, such as the adoption of inadequate data sources in a wide scale, the choice of very extensive areas for analysis or indeed the investigation in areas less favorable to the occurrence of dolines.Keywords: karst; doline; density.

“…These mountains are the largest and most important karst terrain in Turkey. While presenting different lithological and structural characteristics, the Jurassic-Cretaceous and Miocene neritic limestones also played a significant role in developing the karstic landscape of these mountains (Öztürk et al, 2018b;Nazik et al, 2019). In particular, the tectonic history of these units was a determinant factor affecting the properties and density of karst landforms in the Taurus region (Doğan et al, 2017;Öztürk et al, 2018a).…”

“…High plateaus composed of Mesozoic and Tertiary limestones are the characteristic geomorphological units of the Taurus region. The gentle slopes of these plateaus are highly karstified due to tectonic and climatic effects (Klimchouk et al, 2006;Monod et al, 2006;Bakalowicz, 2015;Doğan et al, 2017;Nazik and Poyraz, 2017;Doğan and Koçyiğit, 2018;Öztürk et al, 2015, 2018bKuzucuoğlu, 2019). The plateau surfaces include many landforms such as gorges, dry valleys, dolines, uvalas, ponors, and springs.…”

“…Dolines (enclosed depressions) and karstic dry valleys, also called relict valleys, ancient valleys, fossil valleys, solution valleys, paleovalleys, and paleokarst valleys in various studies (Fermor, 1972;Day, 1983;Doğan and Özel, 2005;Sauro, 2013) are characteristic landforms of the high karstic plateaus in the Central Taurus Mountains (Nazik, 1992;Monod et al, 2006;Doğan et al, 2017;Öztürk et al, 2018b). Karst valleys evolved as normal valleys due to fluvial erosion in the "prekarst phase" of surface development (Dreybrodt and Gabrovšek, 2003;Košutnik, 2007) and date from the Miocene to Pliocene in the Taurus mountains (Monod et al, 2006).…”

Uplift history is an important factor in the structural patterns and karstification of the Taşeli Plateau. The morphological development of the study area consists of five stages according to its sedimentation, rotation, uplift, and climatic properties. (1) Shallow carbonates accumulated during the Early Miocene. (2) An emersion and drainage network developed as a result of the compressional neotectonic regime in the Late Miocene. (3) Dense joint systems were formed due to the ~40° clockwise rotation of the eastern limb of the Isparta Angle. (4) The climate of the study area changed as a result of rapid uplift from Late Pliocene to Early Pleistocene. This caused the formation of dry valleys, underground karstification on the plateau surface, and headward erosion of rivers in the southern part of the area. (5) In the last stage, the plateau surface was densely covered by solution dolines and the dry valley network turned into relict valleys due to expanding extensional cracks during Pleistocene.
