Speleogenesis of the Jankova pecina cave and karst in it's nearby vicinity

Abstract

This paper provides the insight into morpho-hydrologic characteristics and speleogenesis of the Jankova pećina cave and the evolution of karst in the nearby vicinity. Phases in cave evolution, which represents the alternation of accumulative and erosion processes, were analysed. Clogging of existed conduits during the first accumulative phase leads to displacement of the Janko's creek abyss and formation of another entrance along with new, deeper storaged conduits. The strewed parts of the cave were exposed to partial removal of sediments what resulted in exhumation of its oldest products. The opening of the quite new entrance (vigled) during the opposite process and phase of clogging the endure air circulation inside the cave has been changed. As the consequence, the asymmetric forms of stalactites and stalagmites formed. Study of the Jankova pecina cave represents a contribution to better knowledge of accumulative processes as a significant speleogenetic factor.
