| Sumario: | Çakmaktepe Cave is located in source area of Kovalık Creek, which originates from western slopes of Kumalar Mountain in the east of Sandıklı town. The cave developed in partially altered trachytic lava. However, it is a pseudokarstic cave formed by dissolution of relatively easily soluble silicate minerals (feldspars), particularly of sanidine mineral contained by trachytic lava and transport of weathering products (kaolin) by water. Although the cave contains shafts, lateral galleries etc., which are typically found in karstic caves, it contains no stalactite formations. Çakmaktepe Cave formed according to local morphological base level, which showed a downward movement, at the sections where highly altered subvolcanic trachytes exhumed from cover rocks, crop out. Çakmaktepe Cave, which is a morphologically horizontal cave, is important due to its karst morphology; its rare and extraordinary characteristics in respect of cave formations. There are known cave formations, in which chemical dissolution plays an important role in various silicate rocks. In these rocks, chemical dissolution of particularly quartz and feldspars plays an important role in the formation of caves and galleries. However, there are some differences between the cave formation in silicate rocks and cave formations in chemically soluble rocks. The issue remains controversial. Çakmaktepe Cave is of great importance as it will be the first in the world literature to investigate the caves in trachytic lava, where dissolution processes play an important role in cave formation. This study deals with formation of Çakmaktepe Cave through the evaluation of the cave with its surrounding. |
