Geomorphological characteristics and development of the epigenic Buruk swallow hole and Gümüşdere sinkhole (Tavas, Denizli) in the Lycian Nappes region

Abstract

Buruk swallow hole, which developed in the west of the Taurus Mountains karst belt, where surface and underground karst reaches great depths, and Gümüşdere sinkhole, which is actually a collapse doline, are located within the borders of Tavas district of Denizli province. These karst forms, located in a tectonically active region, characterize the polygenic-polycyclic geomorphic development due to thrusting, faulting, grebenization, deeper migration of groundwater zones, and deepening of karst and morphological base levels. Both karst shapes contain morphological shapes and structures that characterize this polycyclic. The swallow hole and the sinkhole were studied in detail in order to reveal these features and evaluate the possibilities of use. For this purpose, strike and slope values were measured in the swallow hole and sinkhole; floor lengths, right-left widths and ceiling distances were measured with a laser meter. According to all these measurement values, the plans of the swallow hole cave and the sinkhole were drawn, and their transverse and longitudinal sections were drawn. In addition, in order to determine the climatic characteristics of the swallow hole cave, the temperature and relative humidity values and the values of different gases (O2, CO, H2S, CH4) were measured. As a result of these measurements, Buruk swallow hole has a temperate and humid weather; It does not have any suffocating and toxic gas excess or less. According to the metric measurements made inside the cave, the swallow hole cave has a total length of 281 m and an endpoint depth of -71.5 m according to the entrance. In addition, the cave consists of two floors, semi-active and fossil. 99 meters of the cave consists of a fossil layer, which ends at -58 meters from the entrance. The cave, which developed in the vadose zone, was exposed to rejuvenation at the very beginning of the development and was buried by meanders in the underground stream bed flowing through it. It characterizes it by having a keyhole morphology. Gümüşdere sinkhole, on the other hand, developed on the western slope of a fluviokarstic depression connected to the Barz Polje from the north. The sinkhole was formed by the collapse of the ceiling of a cave that started to develop at the beginning of the formation period of the polje in the very karstic limestone. This karst depression, which is called a sinkhole by the local people, is actually a bedrock collapse doline with this formation. When evaluated in terms of their morphological features, risks and natural environment characteristics, the swallow hole cave can be evaluated in terms of sinkhole tourism, although it is not suitable for tourism or other purposes.
