“…In Turkey, nearly one third of which is composed of karst terrains, most attention is focused on sinkholes formed in recent years on lacustrine limestone and consolidated non-karst caprocks overlying the limestones near Karapınar in the Konya Closed Basin (KCB) (Fig. 1), rather than on sinkhole hazards in evaporite karst, which are seen across a large area (Dogan and Yes ßilyurt, 2004;Dogan and Özel, 2005). The KCB is comprised of the Konya Plain sub-basin in the south, the Tuz Lake sub-basins in the north and the Obruk Plateau, which is located between these two sub-basins ( Fig.…”

“…Gypsum and gypsum karst has been observed in many regions of the world such as; France (Chardon and Nicod 1996) England (Paukstys et al 1999;Cooper and Waltham 1999;Cooper 1998Cooper , 2002Cooper and Saunders 2002;Lamont-Black et al 2002), Spain (Benito et al 1998;Pulido-Bosch 1999, 2003;Gutierrez et al 2008), Lithuania (Paukstys et al 1999), Ukraine-Russia (Culshaw and Waltham 1987;Andrejchuk 1996;Klimchouk and Andrejchuk 2002), Iraq (Jassim et al 1997), Saudi Arabia (Amin and Bankher 1997), Italy (Belloni et al 1972), Germany (Pfeiffer and Hahn 1972), Romenia (Bleahu 1972), USA (White 1988;Johnson 2005Johnson , 2008 and Turkey (Alagöz 1967;Garipagaoglu 1993;Karacan and Yılmaz 1997;Waltham 2002;Dogan and Ö zel 2005). As stated by Yilmaz (2012), the gypsum karst areas of the Sivas basin, especially the northeast region, are observed as a natural laboratory where researchers interested in this subject will find a source of admiration.…”

“…Dogan and Yesilyurt (2004) investigated the properties of the gypsum karst in the south of İmranlı. In their study conducted in the east of Hafik, which is located in the east of the study area, Dogan and Ö zel (2005) stated that the area was rich in karstic structures such as carrens, dissolution doline, subsidence doline, cave, karstic spring and polje and that karstification began in early Pliocene era. Yilmaz (2007) prepared the GIS-based regional karst subsidence sensitivity map of the area between Zara and Sivas and claimed that karstic sediments could harm engineering structures; he also emphasized the benefits of preparing such maps.…”

Gypsum covers an area of approximately 5 % in Turkey and is mainly found in Sivas basin. Gypsum in the Sivas basin includes many karst structures with various sizes and has a variety of forms that present different conditions offering different morphometric features. Two basic shapes of karstic terrain are reflected in this area offering a wide variety of gypsum karst. The first of these are dissolution dolines which constitute the polygonal karst areas, and the second one is collapse dolines which is deeper karst depressions formed by roof collapse and the accompanying of solutions. The aim of this study was to determine and identify general characteristics of doline in the study area using morphometric measurements and calculations. Density of dolin is very high in study area. The source of the dolines data included 1/25,000 scale digital maps containing elevation and several cartographic attribute interpretations, a very demanding field work and satellite images. The parameters calculated for the study area include depression length, width, orientation, area, perimeter, depth, circularity index, depression density, circularity index, length/width ratio and major axis orientation. This study describes an application of geographic information systems to examine the morphometric and geological features of gypsum karst in Sivas basin. The effect of geologic, structural, and hydrogeologic variables on the morphometry and spatial distribution of depressions are discussed in the study.

“…There is a large number of publications on general karst (e.g., Sweeting 1973;Bögli 1980;Esteban & Klappa 1983;James & Choquette 1984;Ford & Williams 1989), palaeokarst (e.g., Walkden 1974;Wright 1982;Vanstone 1998;Molina et al 1999;Miller & Mitchell 2003;Yılmaz & Altıner 2006;Evans & Reed 2007) and related subjects (e.g., Wray 1997;Crowther 1998;Fiol et al 1996;Di Stefano & Mindszenty 2000;Doğan & Özel 2005;Lepirica 2008;Lipar 2009). But there is little information available concerning karstification in caliches (Vanstone 1996).…”

“…But there is little information available concerning karstification in caliches (Vanstone 1996). Karst or palaeokarst studies related to Turkey are also very limited such as Öztaş (1992), Doğan & Özel (2005), Yılmaz & Altıner (2006).…”

IzvlečekUDK 551.435.8(560) Mushin Eren & Zubeyde Hatipoglu-Bagci: Kraške površinske oblike trdih laminiranih skorij (kalkret) na območju province Mersin v južni Turčiji V članku obravnavamo kalkrete v provinci Mersin v južni Turčiji, ki so tam razširjene v številnih pojavnih oblikah. Na kalkretah se pojavljajo različne skalne oblike, kot so škavnice, dežni žlebiči, korozijske vdolbinice in korozijsko razširjene razpoke. Škavnice in dežni žlebiči so povezani z tipično morfologijo »kupol in grebenov«, imenovani kalkretni tepiji (angl. tepee structure) ali psevdo antiklinale. Škavnice so korozijske oblike skledastih oblik z ravnim dnom in ostrimi previsnimi robovi, ki so nastale z zastajanjem vode na vrhu kalkretnih tepijev. Dežni žlebiči so korozijski žlebovi ločeni z ostrimi grebeni, dolžine do 15 cm. Nastali so z raztapljanjem vodnega filma na nagnjenih površinah, večino blizu vrha kalkretnih tepijev. Korozijske vdolbinice so ozke cilindrični skalne oblike, nastale s korozijo raztopin iz drevesnih debel. Poklinaste škraplje (kluftkarren) so nastale z raztapljanjem vode, ki teče vzdolž razpok. Soobstoj kalkretov in kraških oblik je zanimiv pojav, ki kaže na prehajanje suhe klime v manj suho in vlažno klimo. Ključne besede: zakrasevanje, škraplje, kalkreti, trde laminirane skorje, kvartar, Turčija. The study area is located in the Mersin province where caliches are widespread and occur in a variety of forms such as powdery, nodular, tubular, fracture-infill, laminar crust, hard laminated crust (caliche hardpan), pisolithic crust. The hard laminated crust shows distinctive karst surface features of karren. These include kamenitza, rillenkarren, solution pit and solution enlarged fracture (kluftkarren). First two karst features are common and closely associated with dome-and ridge-like morphologies termed caliche tepees or pseudo-anticlines. Kamenitzas or solution basins are dish-shaped depressions with flat bottom and sharp and overhanging sides which resulted from ponding water mostly at the top of caliche tepees. Rillenkarren are solutional flutes separated by sharp angular ridges, with length of less than 15 cm. They are well developed on the inclined surfaces of surface irregularities at or near the top of caliche tepees and form from sheet flow. Solution pits are narrow, cylindrical shaped karst troughs formed by stemflow drainage beneath trees. The kluftkarrens are products of dissolution by channelised surface water flowing along a fracture. The coexistence of caliche and karst features is important to indicate a climatic change from semiarid to humid conditions.
