Age Determination of Speleothems from Mishin Kamik Cave, NW Bulgaria

The entrance of Mishin Kamik Cave

Mishin Kamik Cave is located in the Western part of Stara Planina (Balkan) Mts, NW Bulgaria. This 695 m long maze cave is entirely phreatic, which makes the cave a geomorphological phenomenon for the country. A characteristic feature of Mishin Kamik Cave is the presence of buried speleothems, such as small stalagmites and flowstone, which implies multiphase speleogenesis. The performed U/Th dating of different speleothem samples proves that the deposits are of Late Pleistocene age.
