Abstract

The Jaskyňa Dezidera Horváta Cave is located in the inner city of the town of Nitra, south of the Kalvária Hill (227.3 m asl.). The Jaskyňa Dezidera Horváta Cave has thus become the longest cave of the karst areas in the Tribeč Mts. It currently reaches a length of 610 m, with a denivelization of 45 m. Several geological, geomorphological, and geochemical methods have been used to clarify the genesis of the cave. The cave evolved in the Jurassic limestones belonging to the Tatric Unit. NW–SE, W–E, and NNE–SSW discontinuities were significant to the genesis of the cave. The raised air and water temperatures in the cave (12.5–13.5°C) and the occurrence of various, not-so-common speleothem types, such as helictites, corraloids, and calcite crystals make this cave unique within the Western Carpathians. The morphology of the cave spaces, together with the increased temperature of the water and cave air, indicates that it could be a hypogenic cave, and even more specifically, a hypogenic-hybrid in origin. During its speleogenesis, the mixing corrosion by mixing of atmospheric waters and groundwater played an important role.

Key words: Western Slovakia, Tribeč Mts., Nitra Karst, Jaskyňa Dezidera Horváta Cave, speleogenesis
